What is Cookie Bite Hearing Loss?
A person with sensorineural hearing loss can have an audiogram curve that looks like a cookie that has a bite taken out of it. This loss pattern is called “cookie bite hearing loss”.
Other names for cookie bite hearing loss are pool hearing loss, soup plate hearing loss or U-shaped hearing loss. A person with this pattern is unable to hear mid-frequency sounds while still being able to hear high and low frequency sounds. Fortunately, this hearing loss pattern is relatively rare
With this condition, a person might be able to hear something like a door slamming, but have a hard time following a conversation.
For the majority of people with cookie bite hearing loss, the reason is genetic rather than from aging, being exposed to loud noises, or illnesses/injuries. Although a person is born with this predisposition, he may not notice a problem for many years.
The symptoms are often slow to appear, with the more serious problems occurring after a person reaches 30 years of age. Many times people are not even aware of the problem until they are between 30 and 40.
Because this is a type of sensorineaural hearing loss, it can’t be cured or avoided. Anyone with this type of problem would require a hearing aid. For this type of condition a specific type of hearing aid is needed. Users need a hearing aid that focuses on amplifying mid-frequency range sounds.
Hearing aids will not be able to restore normal hearing but they will help manage the condition. Cookie bite hearing loss can get worse over time, so the sooner one begins using a hearing aid, the better. It will take a little while to get used to, but proper use of hearing aids will lead someone with cookie bite hearing loss to a better quality of life in the long run.
