The Rabbler is a device that produces random noise or “babble” to mask speech and other sounds in a given environment. It was originally developed for military and intelligence applications to protect classified conversations from eavesdropping.
- Frequency Range: 300 Hz-3600 Hz
- Wired, Signals, Recorders Etc.
- 9V Battery Powered
- Size: 2″ x 3.25″ x .75″
It works by creating a sound field of random frequencies and levels that are similar to human speech but not recognizable as actual words. This sound field effectively masks any nearby conversations or noises, making it difficult for anyone to listen in or record the conversation.
The Rabbler Noise Generator can be useful in a variety of settings, such as secure government facilities, boardrooms, and medical offices where patient privacy is important. It can also be used in homes to protect personal conversations from outside listeners or to provide a sound masking effect for better sleep or concentration.
