Assisted Listening Devices

Assisted listening devices are tools that have been designed to improve the ability to hear in specific listening situations. While some devices amplify sound most target a set sound and make it easier to hear by blocking out all other sounds. These listening devices are not hearing aids, though they do have similar components. A listening device has a microphone that can be placed directly on or hear a sound source. The microphone then picks up the sound that is closes to it; rather it be a voice or a noise. The sound is then transmitted back to the user through speakers, headphones or even their pre-existing hearing aid. Some listening devices are designed for use with a hearing aid while others are designed to be used alone. To eliminate feedback individuals wearing a hearing aid who intend to use a listening device must have a hearing aid with a built in T coil that will eliminate feedback.

Assisted listening devices are typically used by people who have experienced minor hearing loss. People who have difficulty hearing in open settings or have trouble concentrating on certain sounds in large areas also benefit from the use of a listening device. These devices are essentially used for minimizing background noise, reducing the effect of distance between the sound source and person with hearing loss, and overriding poor acoustics such as echo. Additionally in large classroom settings listening devices have been used to enhance all students ability to hear the one professor. By projecting sound throughout a room listening devices are like smaller versions of microphone theater systems.

There are several types of assisted listening device systems depending on the environment, the need for privacy, and how the user will interface with the system. There is not one system that is good for all environments, and for each system, there are pros and cons regarding its uses and features. Assistive listening device technology can be integrated into an existing standard public address (PA) or sound amplification system to transmit the sound signals directly to a person. There are four general types of systems: induction loop (IL), FM (frequency modulation), infrared (IR), and sound field amplification systems.
