Noise Cancelling Intercom System for improving the speech quality in noisy medical treatment environments

The bhi noise eliminating intercom system uses unique fully adaptive Digital Signal Processing (DSP) technology to enable clear voice communications from within noisy environments.  Unwanted background noise and interference is removed or reduced to leave clear intelligible speech. 

The NEIS-RM intercom system is suitable for use in a wide range of noisy environments where the sounds of fans, motors, engines, air-conditioning, traffic etc give rise to poor voice communications at the far end where someone in an office or gatehouse is trying to understand the caller.

The system was designed to improve the voice quality in medical treatment rooms where radiotherapy and CT scanners are installed.  Voice communications between the treatment room and control room will be greatly improved.  This is very important if a patient under treatment becomes stressed and tries to communicate with the control room.  If a normal intercom is used there is a good chance that the patient may not be heard or understood.

The bhi NEIS system consists of a robust, stylish desktop control unit with a “push-to-talk" (ptt) button, connected to a remote “hands free” speaker unit with a connections for a 25ft microphone assembly that can be located to suit the patients position. Operation of the bhi intercom system is simple with connections between the control room and treatment room being made via a single straight cat 5 data cable connection with power being supplied by a medical power supply fitted in the control room side.

Suitable applications include hospital radiotherapy and CT scanner treatment rooms, Mining comms, Help Points, Transport, Refineries, Factories and buildings, drive thru’s, weigh bridges, car park entry systems, toll booths, door entry etc.
