Some people have hearing problems caused by ear wax, which can be removed by the professional. In other cases, middle ear infections cause a temporary hearing loss which can be eliminated after medical treatment. Auditory processing disorders also can contribute to hearing problems.
If any of these situations (or others) are present, your hearing care professional will be able to recognize and diagnose the problem and can manage or refer you to best handle these situations. Before purchasing hearing aids, a hearing evaluation should be obtained by a licensed audiologist or hearing instrument specialist.
