Do you have someone spying on you and you can't figure out how?
Give them something listen to with one of our Acoustic Noise Generators. Most people don't have time to sit and listen to you 24 hours a day so they attach a voice activated recording device and retrieve it later.
These noise generators create an awful white noise that will cause digital voice recorders to run out of memory. And if you turn them up loud enough they will drown out your conversation so it can't be heard or recorded.
