Thebhi NEIS NoiseEliminatingIntercom Systemenables clearvoice
communicationsfromwithinnoisy environments.Using uniqueDigital
Signal Processing (DSP) technology, unwanted noise and
interferencepicked up by the microphone in the communication can
beremovedfromthesignaltoleaveclearintelligible speech.
The NEIS is suitable in a wide range of noisy applications, where
the sounds of fans, motors, engines, air-conditioning, traffic etc.,
give rise to poor voice communications. The system is particularly
useful for improving the voice quality in medical and industrial
environments, where noisy machines can make voice
communicationdifficult.
Usingminimal hardware components, the installationand operation
of the bhi intercom system is very easy, connections being made
viaa single cat 5datacable.The NEIS ispre-configuredfor optimum
noise cancelling, and is fully adaptive to changing environmental
conditions. Itis suited to a varietyofapplications,where clear “noise
