The dos and don'ts when implementing ampetronic hearing loops at your venue

Ampetronic hearing loops are a great facility for any venue. They transmit an audio signal directly into a hearing aid being worn by a person with impaired hearing via a magnetic field. The result is that background noise and other competing sounds are reduced and the clarity of what is being heard is improved. If you’re about to install ampetronic hearing loops at your venue then there are a few dos and don’ts to bear in mind.

The don’ts

  • Avoid installing a perimeter loop on a wall at ear height. If you do that then anyone wearing a hearing aid and standing near the wall will have their hearing aid overloaded and it can also mean general field strength is uneven.
  • Don’t use omnidirectional ceiling or wall mounted microphones. These will pick up all the sound in the room and transmit it into the hearing aid, which only makes the noise ratio issue worse.
  • You’ll need to make sure that the system is working. If you simply install it and then assume it’s functioning fine without testing it because you don’t personally need it then you could quickly run into issues.

The dos

  • Carry out some research at the site before installing anything. In particular you’ll need to assess the electromagnetic background noise and the amount of metal in the construction of the building. Metal loss, in particular, can have a negative impact on the system.
  • Look at what else is going to be in, or near, the proposed loop area. For example, raised steel deck floor tiles or electrical equipment could detract from, or destroy, the intended impact of installing hearing loops in the first place.
  • If you’re using different component parts for your hearing loop system, check with the manufacturers before installing anything to ensure that they are all compatible with one another.
  • Take the time to find the right microphone. Ideally you’re looking for a microphone that captures only the sounds you want to be fed back into the hearing loop and not general or background noise too.
  • If you’re using flat copper tape to install your ampetronic hearing loops at your venue then look out for the obstacles that could interfere with it. These include sharp debris that could ground the loop if it gets through the protective outer layer to the copper underneath.
  • Take steps to try to avoid damage by carpet fitters. For example, installing the loop cable a few centimeters away from the wall and using printed warning tape to indicate the position of the loop cable.
  • Make sure your venue staff have been trained in how to operate the system, as well as how to deal with any of the more basic issues that could arise.
  • Test the system and ensure that it conforms to the relevant safety and performance standards.
