What types of hearing tests are performed?

There are five main tests for children and adults that professionals use to identify hearing loss. None of the tests are painful. Once done audiologists will be able to tell what type of hearing loss the patient has and whether it affects both ears. A case history is taken that looks at past medical problems. This is very important to help with the determining the treatment, so patients are advised to come prepared. 
Pure-Tone Testing – With the use of headphones, this test finds the quietest sound that can be heard at different frequencies or pitches. All information is recorded on an audiogram to help with proper patient diagnosis. The accuracy of this test depends heavily on the participation of the patient.

Speech Testing – Speech testing checks how well patients hear and repeat words. The speech reception threshold is a part of speech testing, and one of the many subtests used in identifying hearing loss. With the results from the pure-tone test, audiologists can compare the two and come to a better conclusion.

Tests of the Middle Ear – Middle ear tests include Tympanometry, Acoustic Reflex Measures and Static Acoustic Impedance. All three of these tests check how well the middle ear responds to sound. In younger children, failing the middle ear test means that they are susceptible to ear infections. 

Auditory Brainstem Response – ABR is all about finding how well the cochlea (inner ear) works with the brain pathway when receiving sound. For patients that can’t complete normal hearing screenings, this also serves as another way to gauge their hearing loss. No patient participation is needed for this test. Once the electrodes are placed on their head, the system will automate the results. 

Otoacoustic Emissions – The OAE test is similar to ABR with how it tests the cochlea. But the big difference is that it measures otoacoustic emissions. Just like ABR, no patient participation is needed. 

Patients will get different tests based on their current hearing problems. The information from the hearing aid evaluation goes a long way in deciding health goals for individuals. It will also help decide the type of hearing aid that will work best on a daily basis. 

There are many brands to choose from

Multiple styles, sizes, brands and compatible accessories allow for an incredible amount of options when choosing a hearing aid. Audiologists will make recommendations, but the final decision is in the hands of the patient. When available, hearing devices may have trial periods of up to two months. This is the perfect way for new users to test out the many features of a product that they’re the most interested in.
