HEARING TESTING AND HEARING AIDS
Hearing tests generally consist of two parts: middle ear measurements and booth testing. Middle ear measurements while booth testing indicates how well a patient can hear normal conversational speech sounds.
Traditional Hearing Aids
A hearing aid is an electronic device worn in or behind the ear of a hearing-impaired person for the purpose of amplifying sound, of handling, volume control, and availability of special features. The best hearing aid for you depends on your hearing loss, your listening and communicative needs, and your lifestyle.
Implantable Hearing Aid Technology
Cochlear Implants – an electronic device that is surgically implanted under the skin with electrodes positioned in the cochlea (organ of hearing) to stimulate the auditory nerve. This device has both internal and external parts and should give the patient sound perception by stimulation of the auditory nerve via the implanted electrode array; usually indicated for patients with severe to profound bilateral (in both ears) sensorineural hearing loss who Bone-Anchored Hearing Aid (BAHA) – a percutaneous device primarily used for patients with conductive hearing loss or single- surgically placed behind the patient’s ear and an external sound processor that can be attached externally at will; this device works by transmitting sound directly to the inner ear via bone conduction.
Assistive Listening Devices (ALDs)
ALDs are devices that can help you function better in your day-to-day communications. They can be used with or without hearing aids or cochlear implants to make hearing easier. Most ALDs can be used with a personal hearing aid that has wireless function or a telecoil to help overcome background noises, minimize the negative impact and sound distortions of distance from the sound source, and to reduce room reverberations. The basic function of an ALD is to improve the “signal-to-noise ratio” for the listener. the undesired sounds (noises) are minimized. The most common types of ALDs for children are Sound Field Systems, FM systems, Infrared systems, and loop systems, and, for adults, the most common type of ALD used is TV Ears.

VIDEONYSTAGMOGRAPHY (VNG) TESTING
VNG testing consists of a series of tests that evaluate how well your eyes, inner ears, and brain work together to coordinate your balance. It will provide information about whether or not a
GANS SENSORY ORGANIZATION PERFORMANCE (GANS SOP) TEST
Gans SOP testing provides qualitative information regarding patterns of equilibrium maintenance by evaluating the use of various sensory inputs (vision, somatosensory, and vestibular) to postural stability.
The Dix-Hallpike test is a diagnostic maneuver used to identify benign paroxysmal positional vertigo (BPPV).
