What types of ALD and accessories are available?
There are several types of systems depending on the environment, the need for privacy, and how the user will interface with the system. There is not one system that is good for all environments, and for each system, there are pros and cons regarding its uses and features. Assistive listening device technology can be integrated into an existing standard public address (PA) or sound amplification system to transmit the sound signals directly to a person. There are four general types of systems: induction loop (IL), FM (frequency modulation), infrared (IR), and soundfield amplification systems.
