Accessories let you get the most from your hearing aid.
Assisted listening devices help improve sound transmission in both large facilities (such as a classroom or a theater) and in small settings with one-on-one conversations
A telecoil (also called t-coil) is an important component of hearing aids that enables assisted listening devices to work. A telecoil is a coil of wire that is already installed into many hearing aids; the coil acts as a miniature wireless receiver. The telecoil is able to pick up electromagnetic signals from various systems and turns that signal into sound inside the hearing aid. This direct connection eliminates the background noise that is distracting to the user and is able to be customized to the user’s needs. For those without a telecoil-enabled hearing aid, other devices such as a headset with loop receivers can be purchased.
A hearing loop system uses electromagnetic energy to transmit sound. The system is made up of four parts: a sound source, an amplifier, a thin loop of wire that surrounds the room and a hearing aid or headset enabled with a telecoil. As long as the user is within or near the room, their telecoil-enabled device is able to directly pick up the sound, eliminating background noise. Hearing loops can be found in places such as theaters and conference centers.
FM systems use radio signals to transmit sound. The speaker will wear a small microphone connected to a transmitter and the hearing impaired individual wears the receiver turned to a specific channel. Those with telecoil-enabled devices do not need a separate receiver; they can wear a wire around their neck to convert the radio signal into an electromagnetic signal that can be picked up by the telecoil. This system is typically used in a classroom setting.
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. This makes this method of transmission ideal for locations where confidential information is being discussed, such as a courtroom.
Bluetooth enabled hearing aids open the door for you to connect with an endless number of devices. Bluetooth works like a telecoil, by connecting you with a device and streaming the sound directly to your hearing aid, eliminating the background noise. Cellular telephones, computers, televisions and MP3 players are only a small list of the Bluetooth enabled devices that exist.
Small, individual microphones can help with one-on-one and small group conversations. The clip on microphone is ideal for a one-on-one conversation. It can be easily clipped onto clothing and everything picked up by the microphone is sent directly to the hearing aid. The pen style is a larger microphone in the shape and size of a pen. It can be worn by one individual, like the clip on microphone, or held out and used to pick up the sound from a group.
Remote controls offer you the ability to adjust your hearing aid without fiddling with small buttons or dials. You can turn your hearing aid on and off, adjust the volume, turn on the Bluetooth connection and even answer your phone, all with a click of a small pocket-sized remote control.
