Hearing tests provide an individual with information about his or her hearing ability and is usually performed by an audiologist with audiometry. An audiogram is used to determine a person’s hearing ability at various frequencies accurately. There are other more straightforward hearing tests available, e.g., the Rose testing and the Rothinger test. Other hearing tests include the AAT, the C Audiogram, and the MTF.
One type of hearing test Adelaide is called audiometry, and it consists of placing the patient in a soundproof room and having them listen to various sounds in sequence, to determine which sound is louder. The patient then has their ears examined by the audiologist, which checks for hearing loss by listening to the sequence of noises. If the person finds that they cannot perceive the sounds clearly, they may have an inner ear imbalance, called sensorineural hearing loss. This type of hearing test is usually performed on children and adults who do not respond to audiometry tests correctly.
Another type of hearing test Adelaide is called neuropsychological testing and is usually used to explore people’s mental processes and thinking. During this type of exam, the person is asked to perform a series of tasks. Sometimes, the person will be given a list of things to do, and sometimes they will be given a list of colours. When they do each task, they will be asked to make sure they heard each sound clearly, and then they will be asked to recall as many of the items as possible. People who have Alzheimer’s disease often require this type of exam to determine their cognitive function level.
An otoscopic exam is often combined with an audiogram to detect people’s earwax buildup. Sometimes, buildup is visible on the outer ear; in other cases, it is invisible. For people who suspect earwax buildup, they can request a special camera is used during their hearing test Adelaide so that they can view it in its entirety. People who are hearing loss often have a buildup of earwax inside their ear canal.
Another form of a hearing test is called tympanometry, which uses tones of different volumes to create an auditory artifact. Different tones produce different sounds. When the audiologist plays back the other sounds, they can determine which sound produces pitches and frequencies. When an audiologist detects tympanometry errors, they often change the frequency of the bleep to compensate. Other types of audiometry tests include electrophysiology or the study of hearing through the nose. With this method, a tiny amount of fluid is injected into the ear; once the fluid comes out, the person feels different tones.
