How does the new device prevent recordings?

By emitting high-frequency sound waves.

What impact does the device have on speech-to-text apps?

Renders them unable to transcribe speech.

Corporate meeting room and various settings.

Some microphones are more resistant than others.

Potential health risks due to loud output.

The newly introduced device disrupts sound recordings by emitting high-frequency waves that interfere with microphone diaphragms, effectively blocking human speech frequencies and speech-to-text apps but may pose health risks due to its loud output.
Various tests reveal that the device's effectiveness varies based on the type of microphone used, with lav mics like the Sanken COS-11D proving more resistant, while larger diaphragm condenser and dynamic microphones are less affected, highlighting limitations in achieving universal protection against hidden recordings.

A device is introduced that prevents conversations from being recorded on hidden microphones or voice recorders.
The device claims to disrupt sound recording by emitting high-frequency sound waves that interfere with microphone diaphragms.
The device's effectiveness is demonstrated through a spectrogram analysis showing how it blocks out human speech frequencies.
The device's impact on speech-to-text apps is shown, rendering them unable to transcribe speech when the device is active.
The device is tested in various scenarios, including a corporate meeting room, where it effectively disrupts recordings but poses potential health risks due to its loud output.
The device's effectiveness is affected by the positioning of the recording device and the presence of clothing layers that block high-frequency noises.
Different types of microphones are tested against the device, with some, like the Sanken COS-11D lav mic, proving more resistant due to unique design features.
Larger diaphragm condenser and dynamic microphones are found to be less affected by the device, indicating that the device is not a foolproof solution for all recording scenarios.
