Product Description

HamiltonBuhl Assistive Listening System

Most of us take hearing for granted. Sound, such as speech, occurs somewhere in the environment around us, and we, quite simply, “hear” it. And, It is well-recognized that hearing is critical to speech and language development, communication, learning and social interactions.

Breakdown learning, communication and social barriers with the HamiltonBuhl ALS700 Assistive Listening System. Separate the sound that your audience wants to hear from the background noise, and deliver it at the right amplification level, directly into the individual’s ear.
