ystem enables clear voice
communications from within noisy environments. Using unique Digital
Signal Processing (DSP) technology, unwanted noise and
interference picked up by the microphone in the communication can
be removed from the signal to leave clear intelligible 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
communication difficult.
Using minimal hardware components, the installation and operation
of the bhi intercom system is very easy, connections being made
via a single cat 5 data cable. The
NEIS
is pre-configured for optimum
noise cancelling, and is fully adaptive to changing environmental
conditions. It is suited to a variety of applications, where clear “noise
free” two-way voice communications are important, including:
Hospital radiotherapy/radiology treatment rooms, mines, railway and
transport depots, customer help points, factories & office
communications. In fact the
NEIS
provides a simple effective solution
for anyone trying to communicate from within a noisy environment.
Simply plug in the power and the system is ready to go.
The
NEIS
consists of a stylish, robust, desktop speaker control unit,
with a “push-to-talk” button, connected to a remote “hands free”
speaker unit, with a remote microphone attached. This allows the
noisy location to be constantly monitored, an important feature for
safety critical environments.
