Assistive Listening Devices (ALDs)

ALDs can increase the loudness of desired sounds, such as a radio, television, or a public speaker, without increasing the loudness of the background noises.

Candidates for ALDs

People with all degrees and types of hearing loss — even people with normal hearing can benefit from assistive listening devices.

Types of ALDs

There are many assistive listening devices available today, from sophisticated systems used in theaters and auditoriums to small personal systems.

The Prevalence of Tinnitus

Tinnitus is the term for the perception of sound when no external sound is present. It is often referred to as “ringing in the ears,” although some people hear hissing, roaring, whistling, chirping, or clicking.

Cause of Tinnitus

Tinnitus may originate from various lesions and from different sites. The auditory system involves highly complicated inner ear structures, many afferent and efferent nerve pathways and a great amount of nuclei that form a complex meshwork.

Tinnitus Treatment and Management

Generally, most patients will not need any medical treatment for their tinnitus. For patients who are greatly bothered by tinnitus, they may use some masking techniques such as listening to a fan or radio which would mask some of their tinnitus.

Cochlear Implants

Cochlear implants are a means of surgical amplification for patients with severe-to-profound sensorineural hearing loss. There is an internal and external device as part of the implant. Appropriately-identified adults and children with severe to profound hearing loss can be implanted starting as early as 12 months of age.
