How does it work?

Using the latest Digital Signal Processing (DSP) technology the bhi range of noise elimination products, will remove unwanted background noise and interference to leave only the speech.

The DSP processes the signal and differentiates the noise from the speech. This unwanted noise and interference is then attenuated to leave only the speech. The DSP technology is fully adaptive and no adjustments are necessary.

The signal is constantly monitored, and the DSP automatically adapts to any changes in the signal conditions.

What can it remove?

Noise can come from two areas
  • Transmitting end
  • Transmission process (interference) and Transmitting noise source.

This type of noise is picked up by the transmitting microphone and passed along with the speech signal to the destination, for example:

  • Road noise
  • Engine noise
  • Wind noise
  • Crowded environments
  • Machinery and equipment
  • Transmission noise (Interference)
  • This type of noise is added to the transmitted signal on route to the destination, for example:
  • Poor reception conditions
  • Weather
  • Other transmitted signals
  • Distance.

The bhi range of noise elimination products can remove both of these types of noise without significantly altering the speech signal.
