Assistive Listening Devices

Hearing Aid Accessories

After working with the top audiologist in Manchester, you have the peace of mind that you are using the best hearing aids for your type and degree of hearing loss. Your hearing is now as good as it can be, right? Wrong. Much like the right accent piece can bring your outfit from a 10 to an 11 so can the right hearing aid accessory.

The most popular hearing aid accessories are assistive listening devices (ALDs). These listening devices enable you to hear and understand voices better than you could with just your hearing aids. Within all modern hearing aids is a small copper coil that acts as a wireless receiver, called a telecoil (also known as t-coil). This telecoil is essential for any assistive listening device.

Common Assistive Listening Devices

The three most common assistive listening devices are below:

A hearing loop (or induction loop) uses electromagnetic energy to transmit sound. The hearing loop consists of four parts: a sound source, an amplifier, a thin wire loop and a receiver. Sound is amplified and converted into an electromagnetic signal. It then travels through the loop and is picked up by the receiver; in most cases this is a telecoil-enabled hearing aid. Since the sound is picked up directly by the hearing aid, the sound is clearer and contains much less background noise. Hearing loops can be found in places such as popular Manchester theaters and conference centers.

An FM system uses radio signals to transmit sound. This system is typically used in a classroom setting. The speaker (usually a teacher or lecturer) will wear a small microphone connected to a transmitter. The hearing impaired individual wears the receiver tuned to a specific channel. Those with telecoil-enabled devices do not need a separate receiver; they simply need to wear a wire around their neck to convert the radio signal into an electromagnetic signal that can be picked up by the telecoil.

An infrared system uses infrared light to transmit sound. A transmitter converts sound into light and sends that light to the receiver worn by the hearing impaired individual. As with the FM system, a telecoil-enabled hearing aid can become a receiver with the help of a wire, worn around the neck. Unlike the FM and hearing loop systems, infrared cannot pass through walls, making this method of transmission ideal for locations where confidential information is being discussed, such as a Manchester courtroom.

Besides for assistive listening devices, there are a number of other hearing aid accessories.

Remote controls are able to wirelessly connect to your hearing aid to let you change the program or volume without having to fiddle with small buttons.

Personal microphones can help assist with one-on-one conversations. They are worn around the neck of your conversation partner and the microphones directly broadcast their voice into your hearing aid without distracting background noise getting in the way. These microphones can also be used in larger group settings by placing them in the middle of the conversation, such as on a table.
