![]() ![]() Macrae dealt with this issue in a rigorous fashion (Macrae, 1991 1995). Essentially the idea is that hearing aids make noises louder, and it is well known that loud noise can cause hearing loss. This is a complex question that has been debated since the 30's. Could a hearing aid or hearing assistive device make hearing worse ? This patient does not need anything louder at lower frequencies, so benefit is minimal. Making things louder at higher frequencies will cause distortion and feedback. The problem here is that there is only a small range of frequencies where making sound louder will help (between 1-2K). There is a very steep drop between 1-2K, and at higher frequencies, hearing is severely impaired. Hearing aids and cognitive decline are correlated with each other, but getting a hearing aid is not very likely to improve thinking, unless you are missing a lot and don't read either.Ī hearing aid will likely go "in the drawer" for a person like this. Hearing aids do very little for balance, and certainly do not prevent vertigo. Most states have a 30 day return policy, some even longer. It is said that 2/3 hearing aids go unworn.

To avoid problems, it is best not to have the same business operation test your hearing and also sell you your hearing aid as well. Generally speaking, a person is not "aidable" if they break the 50-50 rule on their hearing test- if their PTA is > 50, or their WRS is < 50. It is good to have some general rules in mind when you are shopping. Hearing aids may cost about as much as a used car. Hearing aids are high priced devices that are generally sold by small business people (audiologists) who are to some extent, salespeople. Words, hearing aids are usually most appreciated in people with mild to moderate Hearing aids are not indicated for an ear with minor hearing loss,Īnd are also not very useful in an ear with profound hearing loss. On one side can adjust reasonably well to any degree of hearing loss on the Is someone with a mild-moderate bilateral hearing loss, and who has experiencedĪ noticeable communication handicap. In essence, you need a hearing aid if theĬost/benefit ratio is reasonable. We think that life is too short to have a suboptimally functioning sense. We are generally in favor of hearing aids in persons with significant hearing loss. ![]() Hearing aids are electrical devices that assist perception of speech or other ![]()
