	AAA: Hearing Aid FAQs
		If you have a hearing aid on only one ear, say the left one, and the person you wish to hear is speaking to you from the right side, the consonants may be decreased by nearly 20 decibels by the time it gets to your aided ear.
		When there is a large difference in hearing between two ears (as might occur when a person with similar hearing in both ears only wears one hearing aid) the brain cannot make use of these subtle relative differences and their ability to locate sounds may suffer.
		Hearing aid researchers have been investigating the use of true digital technology for over a decade but were held back because the increased power consumption needed to operate such instruments required the instruments to either be very large, or to be connected to a separate power source worn on the body.

	Hearing Aids [NIDCD Health Information]
		Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells.
		For this reason, open-fit hearing aids may be a good choice for people who experience a buildup of earwax, since this type of aid is less likely to be damaged by such substances.
		ITE aids usually are not worn by young children because the casings need to be replaced often as the ear grows.

	Hearing Aid Research
		Although they were all describing digital hearing aids, what struck me was how much the aids seemed to differ from each other, both in features, design, and the nature of the speech processing algorithms they employed.
		All of the hearing aids include some form of wide dynamic range compression, but vary widely in the nature and rapidity of the time constants, threshold of compression (with and without expansion circuits) as well as other parameters relevant to compression amplification (input and/or output compression, compression ratio, etc.).
		This hearing aid incorporates only nine individualized amplification choices, with the claim that one of them will be appropriate for approximately 80% of people with mild to moderate losses (McCandless, Sjursen and Preves, 2000; Preves and Dempsey, 2000; Staab and Preves, 2000).

		Considering also his findings that over 16 percent of people receiving hearing aids have completely rejected them, and that only 60 percent of hearing aid recipients are satisfied with their aids, quite evidently there are shortcomings in current model of hearing aid dispensing that have to be addressed.
