Description

Catenaccio BRMSK — Boardroom Audio Masking & Microphone Suppression System

Protect sensitive conversations from unauthorized audio recording with directional audio masking and microphone suppression.

Catenaccio BRMSK is a professional Boardroom Audio Masking & Microphone Suppression System designed to reduce the ability of nearby microphones to capture protected speech.

Unlike TSCM detection equipment, which is designed to investigate potential surveillance threats, BRMSK provides an active speech-protection layer for the conversation itself.

It is designed for environments where sensitive information must be protected while a meeting, consultation, negotiation or discussion is taking place.

The manufacturer describes BRMSK as a mono-directional audio masking system designed for smartphones, voice recorders, recording pens and similar audio-capture devices, with a current stated effective range of up to approximately 4 metres. Actual performance depends on device type, positioning, microphone orientation, room conditions and protection geometry.

What Is Catenaccio BRMSK?

Catenaccio BRMSK is a directional microphone suppression and audio masking system designed to help protect sensitive speech from unauthorized audio recording.

The system belongs to the broader technology category of:

• Microphone suppression systems
• Audio masking systems
• Speech privacy systems
• Eavesdropping protection technology
• Unauthorized recording prevention
• Boardroom privacy systems
• Corporate information-leakage protection

The core security objective is straightforward:

Reduce the ability of nearby microphones to capture usable speech.

This makes BRMSK fundamentally different from equipment designed to detect or locate surveillance devices.

What Problem Does Catenaccio BRMSK Solve?

Modern recording threats do not always involve a dedicated surveillance device.

A microphone may already exist inside an ordinary:

• Smartphone
• Smartwatch
• Laptop
• Tablet
• Digital voice recorder
• Recording pen
• USB recording device
• Other microphone-equipped electronics

A person entering a confidential meeting may therefore bring a recording-capable device without introducing an obvious RF transmitter or specialized surveillance system.

This creates a different security question:

How can a sensitive conversation be protected when microphone-equipped devices may already be present?

Catenaccio BRMSK addresses this problem at the audio-capture layer.

How Does Microphone Suppression Work?

BRMSK uses directional acoustic interference designed to disrupt microphone recording.

The current manufacturer describes the system as mono-directional interference. Earlier manufacturer technical information describes a combination of ultrasonic emission and acoustic interference, including eight ultrasonic transducers and one acoustic speaker.

The technology therefore operates differently from an RF jammer.

An RF jammer attempts to interfere with radio communications.

BRMSK is designed to interfere with the microphone’s acoustic capture pathway.

The objective is not to disconnect the device.

The objective is to reduce the microphone’s ability to capture the protected conversation.

Directional Audio Protection

Directional protection is one of the defining characteristics of BRMSK.

The manufacturer specifies mono-directional operation and describes the system as suitable for targeted protection in meeting rooms and boardrooms.

This allows the system to be considered for environments where the security requirement is focused on a particular conversation area or potential recording direction.

Potential applications include:

• Boardrooms
• Executive meeting rooms
• Legal consultation rooms
• HR meeting rooms
• Government offices
• Corporate investigation rooms
• Confidential negotiation rooms
• Security-controlled environments

Protection requirements should be assessed against the room geometry, expected device positions and required coverage.

Audio Masking vs. TSCM Detection

Audio protection and TSCM detection address different stages of the security problem.

TSCM Detection

TSCM equipment is intended to investigate potential surveillance threats.

The typical objective is:

Detect → Locate → Identify → Verify

Audio Masking

BRMSK provides an active protective layer during the conversation.

The objective is:

Protect → Reduce Capture → Maintain Speech Privacy

The two technologies can therefore complement one another.

A broader security architecture may use:

TSCM Detection + Device Controls + Audio Protection

Protecting Against Modern Recording Devices

The manufacturer specifically identifies smartphones, voice recorders, recording pens and similar audio-capture devices as target device categories.

This matters because a modern recording threat may look completely ordinary.

A smartphone can function normally while its microphone is used for recording.

A recording pen can appear to be an ordinary writing instrument.

A digital recorder can store audio locally without transmitting it.

BRMSK addresses the microphone-capture component of this threat rather than attempting to identify the physical device.

AI Threat Protection

Protecting Sensitive Speech in the Age of AI

Modern recording systems can do more than simply store audio.

Captured speech can potentially be:

• Transcribed
• Summarized
• Translated
• Classified
• Analyzed
• Converted into structured information
• Distributed digitally

This creates a new dimension of information-leakage risk.

The threat is no longer simply:

“Someone recorded the conversation.”

It can become:

“Someone captured the conversation and converted it into usable intelligence.”

Catenaccio BRMSK incorporates an AI Threat Protection capability within its product positioning.

The manufacturer specifically describes AI Threat Protection as addressing the rise of AI-enabled listening devices and advanced eavesdropping systems capable of unauthorized data capture from intelligent devices.

BRMSK addresses this risk at the microphone-capture layer.

Why AI Changes the Recording Threat

Traditional recording can follow:

Capture → Store → Review

AI-enabled recording can potentially become:

Capture → Transcribe → Analyze → Summarize → Distribute

That can reduce the time between a conversation and the creation of actionable information.

For organizations protecting commercially or operationally sensitive information, reducing unauthorized audio capture can therefore become part of a broader information-security strategy.

AI Threat Protection Does Not Mean AI Detection

Catenaccio BRMSK does not identify whether a device contains artificial intelligence.

It does not identify an AI model.

It does not disable AI software.

It does not guarantee protection against every AI-enabled sensing or recording system.

Its role is narrower:

Reduce microphone-based audio capture from modern recording devices, including devices that may use AI-based transcription or analysis.

Actual performance remains dependent on the recording device, microphone architecture, distance, orientation and acoustic environment.

Is Catenaccio BRMSK an RF Jammer?

No.

BRMSK is an acoustic microphone-suppression system, not an RF communication jammer.

The manufacturer explicitly states that BRMSK does not block:

• Cellular signals
• Wi-Fi
• Bluetooth
• Calls
• Messages
• Applications

Instead, it is designed to disrupt microphone recording performance while allowing the device to remain active and connected.

This distinction is important when selecting security technology.

If the requirement is:

“Block radio communication.”

BRMSK is not the appropriate technology category.

If the requirement is:

“Reduce microphone-based capture of a protected conversation.”

BRMSK is designed for that requirement.

Does BRMSK Block Cellular, Wi-Fi or Bluetooth?

No.

BRMSK does not function as a cellular, Wi-Fi or Bluetooth jammer.

A protected smartphone may remain connected to:

• Cellular networks
• Wi-Fi
• Bluetooth
• Applications
• Messaging services

while the microphone-capture pathway is being targeted.

The manufacturer explicitly states that communication and applications are not blocked.

Can BRMSK Protect Against Smartphones?

Yes.

The manufacturer specifically positions BRMSK for modern smartphones, including current Apple and Android devices.

However, smartphone performance should not be interpreted as identical across every model.

Modern smartphones may use:

• Multiple microphones
• Beamforming
• Noise cancellation
• Computational audio
• Digital signal processing

Actual suppression therefore depends on the individual device and environment.

Can BRMSK Protect Against Recording Pens?

Yes.

Recording pens are specifically identified by the manufacturer as a target device category.

This is particularly relevant because recording pens can operate independently of wireless communications and may use local storage.

BRMSK addresses the microphone-capture pathway rather than relying on wireless transmission detection.

Can BRMSK Protect Against Digital Voice Recorders?

The manufacturer identifies voice recorders among the audio-capture devices the system is designed to disrupt.

Actual performance depends on:

• Microphone architecture
• Distance
• Orientation
• Recorder design
• Acoustic conditions
• Environmental interference

Can BRMSK Detect Hidden Microphones?

No.

BRMSK is primarily a protective microphone-suppression system.

It does not automatically:

• Detect hidden microphones
• Locate surveillance devices
• Identify a recording device
• Determine who is recording

If the requirement is:

“Find the device.”

Use appropriate TSCM detection technology.

If the requirement is:

“Protect the conversation.”

BRMSK is the relevant technology layer.

Can BRMSK Replace a TSCM Sweep?

No.

A TSCM sweep and microphone suppression serve different purposes.

TSCM inspection may investigate:

• RF activity
• Wireless devices
• Concealed electronics
• Hidden cameras
• Non-linear electronic responses
• Suspicious installations

BRMSK provides an active acoustic protection layer.

The two can therefore be complementary:

Detect the environment → Protect the conversation

Why Use Audio Protection After a TSCM Sweep?

A TSCM inspection represents an assessment of an environment at a particular point in time.

The threat can change when people enter the room.

A participant may bring:

• Smartphone
• Smartwatch
• Voice recorder
• Recording pen
• Laptop
• Tablet
• Other microphone-equipped device

An environment that was clear during an earlier inspection can therefore contain new recording-capable devices later.

Active audio protection provides a second security layer during the live conversation.

How to Protect a Confidential Meeting

A professional speech-privacy architecture can combine:

Threat Assessment

Identify what information requires protection and what the consequences of unauthorized disclosure would be.

Physical Controls

Control access to the protected environment.

Device Controls

Define what recording-capable devices are permitted.

TSCM Inspection

Investigate the environment for potential surveillance technology.

Acoustic Protection

Use microphone suppression and audio masking during sensitive conversations.

Operational Controls

Establish meeting, recording and information-handling procedures.

Review

Evaluate incidents, exceptions and security improvements.

BRMSK primarily provides the:

Acoustic Protection

layer.

Boardroom Privacy Protection

Boardrooms can contain highly sensitive information involving:

• Mergers and acquisitions
• Corporate strategy
• Financial decisions
• Investment information
• Pricing
• Intellectual property
• Legal strategy
• Personnel decisions
• Negotiation positions

The threat does not necessarily require a dedicated surveillance device.

An ordinary smartphone can contain multiple microphones.

An ordinary smartwatch can contain a microphone.

A digital recorder can store audio locally without transmitting.

Catenaccio BRMSK is designed to address this microphone-based capture risk.

Executive Office Privacy

Executive offices can contain sensitive discussions involving:

• CEOs
• Board members
• Senior executives
• Legal teams
• Security teams
• Corporate investigators

BRMSK can provide an additional technical speech-privacy layer where the consequences of unauthorized recording are significant.

Legal Consultation Rooms

Legal consultation rooms may involve confidential discussions and sensitive information.

BRMSK can provide an additional technical privacy layer within authorized professional environments.

It does not itself create:

• Legal privilege
• Attorney-client privilege
• Confidentiality
• Regulatory compliance

Those matters depend on the applicable legal and professional framework.

Government and Sensitive Facilities

Government and other sensitive environments may require stronger controls around confidential conversations.

Potential applications include:

• Government meeting rooms
• Restricted conference rooms
• Sensitive administrative offices
• Diplomatic environments
• Security-related meeting spaces

Deployment should be evaluated against applicable organizational and regulatory requirements.

Corporate Investigations

Sensitive internal investigations may involve:

• Employee interviews
• Internal disputes
• Compliance matters
• Fraud investigations
• Security investigations
• Sensitive personnel discussions

Speech privacy can therefore form part of a broader investigation-security architecture.

Confidential Negotiations

Commercial negotiations may expose information with substantial financial value.

Examples include:

• Acquisitions
• Joint ventures
• Strategic partnerships
• Supplier negotiations
• Investment discussions
• Pricing negotiations
• Contract negotiations

Protecting the conversation can therefore form part of protecting the commercial value of the information being discussed.

One BRMSK or Multiple Units?

BRMSK is a directional system.

The manufacturer states that multiple units can be used for larger spaces and multiple potential recording directions.

The appropriate number depends on:

• Room dimensions
• Seating arrangement
• Protected directions
• Potential device positions
• Acoustic characteristics
• Required protection level

The current manufacturer page specifies an effective range of up to approximately 4 metres, while its FAQ provides device-specific figures under particular conditions. These figures should not be interpreted as one universal protection radius.

Professional procurement should therefore be based on the actual room and threat model rather than maximum advertised distance alone.

BRMSK vs. RF Jamming

Requirement	Catenaccio BRMSK	RF Jammer
Protect spoken conversation	Primary purpose	Not primary
Microphone suppression	Designed for this	Not primary
Cellular blocking	No	Different technology
Wi-Fi blocking	No	Different technology
Bluetooth blocking	No	Different technology
Acoustic interference	Yes	No
Speech privacy	Primary application	Indirect
TSCM detection	No	No

The distinction is simple:

BRMSK targets the audio-capture pathway.

RF jamming targets radio communications.

They are not interchangeable technologies.

BRMSK vs. TSCM Detection

Requirement	TSCM Detection	Catenaccio BRMSK
Find suspicious RF devices	Yes	No
Investigate concealed electronics	Model-dependent	No
Detect potential hidden microphones	Method-dependent	No
Protect a live conversation	Not primary	Yes
Suppress microphone capture	No	Yes
Detect hidden cameras	Model-dependent	No
Speech privacy	Indirect	Primary
Replace the other technology	No	No

A mature security architecture may use both.

Detect the environment. Protect the conversation.

BRMSK vs. Physical Device Restrictions

Some organizations prohibit smartphones and recording devices in sensitive meetings.

This can remove many recording sources.

However, physical device restrictions and acoustic protection solve different problems.

Device restrictions attempt to remove recording-capable hardware.

Acoustic protection attempts to reduce microphone capture when microphone-equipped devices remain present.

For high-value meetings, organizations may use both.

BRMSK vs. Software Microphone Controls

Software-based microphone controls can restrict microphones on managed devices.

They may not address:

• Unmanaged personal devices
• Dedicated voice recorders
• Recording pens
• Unknown electronics
• Devices outside organizational control

BRMSK provides a separate environmental protection layer that does not depend exclusively on software configuration.

Technical Architecture

The current manufacturer describes BRMSK as a mono-directional audio masking system. Earlier manufacturer technical information identifies two suppression approaches:

• Ultrasonic emission
• Acoustic / white-noise interference

Earlier documentation also identifies eight ultrasonic transducers and one acoustic speaker.

The current commercial specification should take precedence where current and historical information differ.

Ultrasonic Microphone Suppression

Ultrasonic emission is intended to create acoustic interference that affects microphone recording performance.

The manufacturer describes this as a silent form of protection because the ultrasonic component is outside normal human hearing.

However, microphone response varies between devices.

Performance may depend on:

• Microphone architecture
• Frequency response
• Digital signal processing
• Distance
• Orientation
• Acoustic environment
• Physical obstructions

Ultrasonic protection should therefore not be represented as universally effective against every microphone.

Acoustic / White-Noise Protection

BRMSK also incorporates an acoustic interference component.

This provides an additional suppression mechanism alongside ultrasonic emission. Earlier manufacturer documentation describes combining silent ultrasonic emission with audible acoustic interference for stronger speech protection.

The operational trade-off is straightforward:

More acoustic interference can provide additional protection while potentially affecting participant comfort and meeting usability.

AI-Enabled Recording and Real-Time Transcription

The rise of AI-enabled recording changes the consequences of unauthorized audio capture.

A device may potentially transform:

Capture → Transcribe → Analyze → Summarize → Distribute

rather than simply:

Capture → Store

This makes microphone protection increasingly relevant to information-security strategy.

Potential concerns include:

• AI meeting recorders
• Voice-to-text systems
• Automated meeting summaries
• Smartphone transcription
• Intelligent voice assistants
• AI-enabled recording devices

BRMSK should nevertheless be evaluated against the actual microphone technology involved.

AI Threat Protection Is Not AI Detection

AI Threat Protection does not mean that BRMSK identifies artificial intelligence.

It does not:

• Detect an AI model
• Identify an AI application
• Disable AI software
• Analyze whether a device is using machine learning

Its role is:

Protect the microphone-capture pathway used by modern intelligent recording systems.

That distinction is important for accurate product positioning.

Can BRMSK Stop AI Transcription?

BRMSK is not a software-level transcription blocker.

Its role is to reduce microphone capture.

If a recording device cannot capture sufficiently usable speech, downstream transcription may also be affected.

However, the outcome depends on:

• Recording device
• Microphone architecture
• Signal processing
• Distance
• Orientation
• Acoustic conditions
• Transcription system

Therefore, BRMSK should not be described as a guaranteed AI-transcription blocker.

Can BRMSK Protect Against AI Listening Devices?

The manufacturer explicitly positions BRMSK’s AI Threat Protection around AI-enabled listening devices and advanced eavesdropping systems.

The technically accurate interpretation is:

BRMSK is designed to reduce microphone-based audio capture from modern intelligent recording devices.

It is not a universal blocker for every AI-enabled sensing system.

What Catenaccio BRMSK Does Not Do

Catenaccio BRMSK does not automatically:

• Detect hidden microphones
• Locate surveillance devices
• Identify who is recording
• Determine hostile intent
• Block cellular communications
• Block Wi-Fi
• Block Bluetooth
• Disable recording applications
• Guarantee that every recording becomes unusable
• Guarantee that every microphone is suppressed
• Replace a professional TSCM inspection
• Guarantee complete room confidentiality

Its purpose is narrower:

Reduce the ability of nearby microphones to capture protected speech.

Performance Considerations

Actual performance can depend on:

• Device type
• Microphone architecture
• Distance
• Microphone orientation
• Room acoustics
• Physical obstructions
• Background noise
• Signal processing
• Noise cancellation
• Protection direction
• Number of units
• Room geometry

The current manufacturer states an effective range of up to approximately 4 metres and separately provides device-specific figures under particular conditions. These figures should be treated as manufacturer specifications rather than universal guarantees.

• Device-control policies
• Required protection level

Why Choose Catenaccio BRMSK?

Catenaccio BRMSK is designed around a specific security problem:

Protect sensitive speech against microphone-based recording.

Its value is not simply that it is another security device.

It provides a technical layer between:

TSCM Detection

and

Meeting-Level Information Protection

The broader architecture becomes:

Detect → Control → Protect → Verify

For organizations where spoken information can have significant commercial, legal, governmental or operational value, protecting the conversation itself can be an important part of the security strategy.

Final Takeaway

Catenaccio BRMSK is a professional Boardroom Audio Masking & Microphone Suppression System designed to reduce the ability of nearby microphones to capture protected speech.

It is:

Not an RF jammer.

Not a TSCM detector.

Not a hidden-microphone locator.

Not a universal recording blocker.

It is an active acoustic protection layer.

Its role is to reduce microphone-based audio capture during sensitive conversations.

With its AI Threat Protection positioning, BRMSK also addresses the growing concern that captured speech can be immediately transformed into transcripts, summaries and actionable information by intelligent recording and AI-enabled systems.

The correct security architecture is therefore not:

“Buy one device and the problem disappears.”

It is:

Detect → Control → Protect → Verify

Catenaccio BRMSK provides the Protect layer.

For organizations protecting boardroom discussions, executive meetings, legal consultations, government conversations, corporate investigations and other high-sensitivity communications, that distinction is the reason the technology exists.

Notes : The noise you can hear during the test video is ultrasonic noise being captured by the video recorder being used to record the event.

• The whole demonstration was performed in silent emission mode.
• No noise can actually be heard in the room whilst testing was commencing.
