In search of the silent tone, today we are at brooks-acoustics.com, an acoustics engineering firm. Brooks Acoustics, a acoustics engineering firm that has been around since 1956, has examined NASA data that evaluates structural vibration and resulting sound pressure waves The slides presented indicate that many can detect low-level house vibrations and the associated low pressure sound waves.
For those that have a silent tone as their unwanted house guest, that no one else hears, you may want to investigate sound pressure meters. If you know an audiophile, you may want to ask them questions or even ask them if they have a precision sound meter they could use to measure sound pressure waves. Better yet, talk to an audio engineer. The Audio Engineering Society may just have a chapter that meets regularly in your neighborhood.
About the Silent Tone
The silent tone is a tone that has been associated with smart power meters and the smart power grid. Often only those that are audio sensitive can hear it. Its is believed to be a low-energy audio tone, between 5 Hz and 300 Hz. Cross-breezes from open windows have been reported as a method to reduce silent tone amplification.
The Silent Tone also refers to high frequency electromagnetic waves that are generated from cell phones, wifi and other wireless communication equipment.
