Hearing AID Trial and Fitting
Audiometry tests can be used to diagnose various types of hearing loss, including conductive, sensorineural, and mixed hearing loss. They are also used to monitor the progression of hearing loss over time, and to determine the effectiveness of hearing aids or other treatments
Auditory brainstem response (ABR) and Otoacoustic emission OAE ABR (Auditory Brainstem Response) and OAE (Otoacoustic Emissions) tests are two types of diagnostic tests that are commonly used in audiology to evaluate hearing. ABR test measures the electrical activity of the auditory nerve and brainstem in response to sound stimuli. The test involves placing electrodes on the scalp and recording the electrical responses generated by the nerve and brainstem in response to sounds presented through headphones. ABR test can help determine the degree and type of hearing loss, especially in newborns, young children, and individuals who cannot provide reliable responses to conventional hearing tests. OAE test, on the other hand, measures the sounds produced by the inner ear in response to sound stimuli. A small probe is placed in the ear canal, and a sound stimulus is presented. The test measures the sounds that are reflected back from the inner ear, called otoacoustic emissions. OAE testing can help detect hearing loss caused by damage to the outer hair cells in the inner ear, which is often the first site of damage in noise-induced hearing loss. It has been also a screening device used in screening hearing loss in new born.
