A hearing aid is composed of a microphone, an amplifier, a speaker, and a power supply, which have been miniaturized into a device that can be worn on or in the ear.
The hearing aid evaluation usually takes about an hour. In addition to evaluating your hearing, the professional should help you understand hearing devices and what you might need for the best hearing results. We categorize hearing aid type primarily by where the device is worn. Conventional hearing aids include: Behind-The-Ear (BTE), In-The-Ear (ITE), Completely-In-the-Canal (CIC), and CROS Hearing Aids (contralateral routing of offside signal).
An Extended Wear Hearing Aid is a type of hearing aid that is placed deep in the ear canal and can be worn for several months at a time without removal (e.g., Lyric). This type of hearing aid is primarily suited for people who have mild to moderately severe hearing loss.
Most hearing aids are used by people with sensorineural hearing loss, but there are cases of conductive hearing loss in which use of a conventional hearing aid isn’t possible, such as “aural atresia”. This can sometimes be surgically repaired when a child is older. But in the mean time, it’s important for the child to receive sound. A special type of hearing aid, called a bone conduction hearing aid, serves this purpose.
To overcome some of the disadvantages of bone conduction aids, such as uncomfortable fit and poor sound quality, a new type of device, called bone anchored hearing system or bone conduction implant, has been developed. These are primarily for people with conductive or mixed loss hearing impairment or unilateral deafness. They consist of a surgically implanted titanium post, an external abutment or base that connects directly to the post, and a sound processor.
With a conventional hearing aid, sound is delivered to the ear canal by a speaker or earmold. But for some people, this process isn’t effective or isn’t practical. There are now some implantable hearing aids (middle ear implants) available either commercially or in clinical trials which work through the mechanical function of the middle ear, just like conventional aids ultimately do.
At House Clinic, we offer all technologies of hearing aids to help you achieve the best hearing results possible.
