1075-70 Noisy Location Handset for Avaya T7000/M3900/i2000

The 1075-70 Noisy Location Specialty Handset is for Avaya (heritage Nortel) T7000/M3900/i2000 series telephones. Using original manufacture’s equipment, this specialty handset offers a reliable and effective solution for improving voice transmission in noisy locations. The 1075-70 makes it easier for the remote party to hear what is said.

Algo Noisy Location handsets operate by reducing audio transmit levels, thereby reducing sidetone and the impact of background noise on speech transmission.

Common application environments include:

  • Factory/Plant/Utility
  • Nightclub
  • Financial services (e.g. banking, stock broker)
  • Dispatch


Algo specialty handsets meet stringent electrostatic discharge (ESD) requirements.

Digital telephones include electronic circuitry that provides an effect called “sidetone”. This has the effect of allowing a caller to be able to hear their own voice through the telephone earpiece. For example, by blowing into the mouthpiece of a telephone handset sidetone is heard as the sound transmitted through the earpiece.

Sidetone is beneficial as it provides audible feedback to the caller that the telephone is working. In loud environments, however, sidetone can become excessive as the handset microphone picks up background noise and transmits it through to the earpiece. Not only does this make it more difficult to hear the remote party, it also makes it unpleasant to use the telephone.

By operating with lowered audio transmit levels, the 1075-70 reduces the pickup of background noise and, in turn, sidetone. This allows the near-end caller to hear the remote caller more clearly. It also reduces the background noise transmitted to the remote caller making it easier for them to hear what is said.
