Goldline PWN1
Personal White Noise Generator

Goldline's 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.  Acoustic masking is where a low-level background sound is added to an area in order to:

• Make other noise coming into an area less distracting or
• Reduce the chance of overhearing adjacent conversations or
• Reduce the chance of having your conversation overheard by someone else.
• Aid in alleviating the effects of tinnitus by providing a low-level broad-band noise to help achieve the "habituation" of tinnitus.

The 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 1/4” output jack.  This would allow for a broader reaching noise pattern.

Care should be taken when doing this as too high a noise signal input could result in damage to the sound system.  White noise produces much more high frequency noise than low frequency noise and could damage tweeter speakers at elevated levels.  Many people mistakenly believe that their 1000W speakers can't be damaged with their 250W amplifiers - until they find the tweeters were rated for 100W.  Always start with the gain control of the PWN1 at its lowest position when powering up a sound system.

The PWN1 can be powered with a standard 9 Volt battery or can be powered with the battery eliminator provided.  Plugging the BE1 battery eliminator into the PWN1 disconnects the battery (if installed) from the circuit so that only the BE1 is actively powering the PWN1.

NOTE: There is no provision for the recharging of batteries in the PWN1.
