PWN1 Personal White Noise Generator
The Model PWN1 Personal White Noise Generator produces an adjustable audible random sound with an equal amount of energy per Hertz (Hz) of bandwidth, normally referred to as “White Noise”. This sound can be used to acoustically mask a selected environment. The Model PWN1 has a built in speaker which allows the user to put background noise wherever he/she wants. Place the Noise Generator right next to you on a desk or table or on the other side of the room. The volume control permits the injection of only as much noise as is needed. The idea is not to overpower the offending noise or conversation but to inject just enough random sound to make it less distracting. The noise signal can also be patched into a sound system through the ¼” output jack. This would allow for a broader reaching noise pattern.
l Make other noise coming into an area less distracting
l Reduce the chance of overhearing adjacent conversations
l Reduce the chance of having your conversation overheard by someone else
l To aid in alleviating the effects of tinnitus by providing a low-level broad-band noise to help achieve the "habituation" of tinnitus
