- Covers up to 150 sq ft per unit
- Noise changes in pitch and volume, so it is hard to filter
- Volume knob sets the level
- Works against microphone-based recording
The AJ-34 is an audio noise generator for private conversations. Its speaker plays white noise that keeps changing in pitch and volume. Microphones nearby record the noise instead of clear words, and that kind of noise is hard to filter out later.
Turn the knob to start it and raise the volume until it is loud enough. Speak to test that you can still hear each other comfortably.
One unit covers up to 150 square feet. For a larger room, add one unit for each extra 150 square feet. It runs on one 9V battery, included.
Use it to keep your own conversations private in your office, meeting room, car or home. It is a sound masker, not a radio device, so it does not affect phones or wireless signals.
