A Summary On Hearing Evaluations

By Ann Myers


In the broad course of audiology, specialists with the specialty in assessing a person hearing ability are referred to as audiologist. Before evaluation, screening is done so as to separate individuals free of listening loss from those affected. The procedure of screening those problems is a quick and cost effective compared to that of evaluation as it involves few questions by the specialist mainly on medical and hearing history. Those that fail the screening test repeatedly are subject to hearing evaluations.

The main purposes of evaluations are determining nature and extent of hearing loss that the patient is suffering from. Listening loss is dependent on type, degree, and configuration of impairment. Also, it is done so as to know the cause and the extent of the listening impairment and the major reason being to know the ideal treatment options that are to be applied so as to relieve and eradicate the problem. The audiologist will use an autoscope along with other different tests to evaluate the patient.

Adults and children are subjected to different means of testing. This is because the test is dependent on many factors and mainly the age. Self-assessment is recommended before making an appointment with a specialist so as to be able to give comprehensive details on the problem. Some simple techniques are used to know whether infants and toddlers are okay by observing on how they respond to loud noises using body motions. Various tests are used in the evaluation.

Pure-tone examination method works effectively on all individual. Its mode of action is simple, and it works by recording the extent of the highness or lowness of the sound that an individual will hear. Devices that resemble normal earphones are worn so as to pass the impulse and transfer the sound. Interpretation of an audio is by an audiogram depending on whether experiments on sight or it is conditioned to respond to sound accordingly.

Examination of speech and keenly listening is a method widely used. The minimum and maximum limits of voice are noted. This can be achieved in a silent or noisy place so as the get accurate but varying results. Those symptomatic for hearing loss will have a hard time listening intended message, and they are acted upon accordingly by the specialist.

Tests on middle ear functioning is also an ideal test. It is carried mainly in preschool children. Measurement of the test includes detection of fluid in the ear, the air and the appearance of an eardrum, tympanometry. Static and reflex measurements also examine the possible location of impairment and the physical air volume. Auditory brain response system assesses information on the inner ear and brain nerves and connections for listening.

Treatment of this impairment is achieved after different levels of assessment, and the patients have advised accordingly. Regular checkup and audiological rehabilitation are applied. Technology in listening aids is helpful for continuous training as one can personally use them by self-adjustments. Noise and listening loss prevention is essential. Environments with noises should be avoided and those working there should have the required protective measures.

Evaluations are more than just perceiving and general screening it is a process that requires a specialist with much training on the subject.
