Linus Tech Tips・2 minutes read
A device disrupts sound recordings through high-frequency waves, blocking speech frequencies and impacting speech-to-text apps, with varying effectiveness against different microphones and potential health risks.
Insights
- 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.
