Listen Technologies understands the need to be able to hear clearly in any environment. We design and manufacture Assistive Listening Devices, leveraging several technologies to provide clear, focused, and personalized listening experiences for anyone, even in the most noisy and difficult environments. Assistive Listening Devices are to be made available by law in public spaces where sound is amplified. Many other public facilities incorporate Assistive Listening Devices as a service to their patrons. Assistive Listening Devices are designed using the appropriate technology to provide the listener with the best experience possible. Whether it be our tried and true RF technologies being used for tour groups or for entire stadiums, or a complex loop system integrated in a theatre, Listen Technologies has the right product to fit your needs.
What is Assistive Listening?
Assistive listening involves using an Assisted Listening Device (ALD) to amplify sound and bring it directy to the ear. These devices are able to filter out the desired sound from background noise—enhancing the sound the user hears.
How Assistive Listening Devices Work
Assistive listening devices (ALDs) are small amplifiers that bring sound directly to the ear of ther user. They separate the sounds, particularly speech, that a person wants to hear from background noise—improving the “speech to noise ratio”. They can be used with or without hearing aids or a cochlear implant. These devices help improve hearing during phone conversations, in theatres or a lecture hall, during tv shows or movies, in places of worship, and have many other everyday uses. There are four main assistive listening devices.
An FM System is a wireless assistive hearing device that transmits sounds directly from the source of the receiver. This type of ALD can be used to improve the use of hearing aids, a ochlear implant, or on its own without either device. They work to reduce background noise in particularly noisy places.
A hearing loop, or induction loop, uses telecoils to magnetically transmit sound directly to hearing aids and cochlear implants through a magnetic field. They work to reduce background noise and other competing sounds in loud environments. These systems use a wire, or flat copper tape of loop(s) that are typically installed on the floor of a venue.
An infrared hearing system is a is a popular alternative to an induction loop system. A typical system consists of an audio source, an infrared radiator (transmitter) and infrared listening receivers.
