ASSISTIVE LISTENING DEVICES
An assistive listening device (ALD) is type of device that can help you function better in your day-to-day communication situations. An ALD can be used with or without hearing aids to overcome the negative effects of distance, background noise, or poor room acoustics. So even though you have a hearing aid, ALDs can offer greater ease of hearing (and therefore reduced stress and fatigue) in many day-to-day communication situations.
Types of ALDs?
- 1. Personal frequency modulation (FM) systems The personal FM system consists of a transmitter microphone used by the speaker and a receiver used by you, the listener. The receiver transmits the sound to your hearing aid either through direct audio input or through a looped cord worn around your neck. FM systems can also be hooked up to a TV or a stereo
- 2. Induction Loop Systemsare most common in large group areas. They can also be purchased for individual use. When you switch your hearing aid to the "T" (telecoil/telephone) setting, your hearing aid telecoil picks up the electromagnetic signal, and you can adjust its volume through your hearing aid.
- 3. Acoustic Telephone - Designed and Manufactured as per the needs of the hearing impaired individuals. Provides higher intensity of sound output during telephonic conversation.
