Get to Know Assistive Listening Devices

Your everyday life just got a lot easier – when you’re hearing impaired or hard of hearing there are a variety of options available to you to make listening easier. Assistive listening devices (ALDs) are made to help aid you in hearing and comprehension of conversation.

As a general rule, an ALD will have three basic components:

  • Microphone
  • Transmitter
  • Receiver

As it turns out, most ALDs also fall into three general categories, outlined below.

Infrared

Infrared devices make use of visual, light-based technology and are commonly utilized on occasions when privacy and confidentiality are prized, which include court proceedings or business meetings. Due to the fact that light can’t pass through walls, infrared devices ensure privacy. They’re also seen frequently in entertainment venues and in the use of TVs and video players.

Inductive loop

Inductive-loop devices make use of electromagnetic technology and are commonly utilized in multi-person settings in which more than one person with hearing loss is involved. Inductive-loop devices ensure that reception elements do not need to be worn on the body. They also do not require use of hearing aids – inductive-loop devices can be used with simply headphones and a receiver.

FM

FM devices make use of radio broadcast technology and are commonly utilized in classrooms. Varying degrees of mobility are offered with these types of devices, namely when the transmitter is being worn on the user’s person. Additionally, newer ALDs can have a hearing aid attached.
