Learning How Audiometers Work To Asses Hearing

By Mamie Conrad


Innovations in technology has realized breakthrough in many areas of life. Consider the medical field for instance processes in this area of practice continue to gain immensely with newer and more complex diagnosis for conditions that can now be effectively treated. The use of equipments like the audiometers has made auditory evaluation more effective and enabled patients to get adequate medical advice.

Generally a working ear is an important functional unit for the body. As such when hearing is impaired it is likely to affect the way a person carries out their life activities. In fact hearing is among the five senses that a person relies on to work normally within their environment. Therefore a defect in this area is always an anxious moment and trouble for the patient requiring a quick solution.

Generally the ear is created in such a way as to clearly distinguish between different sounds with the help of a decoding process carried out within the brain. Sometimes a part of the ear is damaged because of trauma or disease. Therefore a person can lose usage of such an ear with the level of deafness depending on degree of the damage.

Generally this condition cannot be changed and so only hearing aids can be used in some cases to ease the condition. It becomes more critical for people who mainly depend on their ears to carry out the life activities around them. Therefore the hearing aids will be used to capture sound from the environment and artificially deliver it to the nerves into the brain for interpretation. In this way the patient may gain some use for such an ear.

Primarily the computer is used here to evaluate hearing loss. This system typically consists of special hardware and software whereby it is configured to record a particular level of accuracy during diagnosis. Part of this system captures the sound from the environment and transfers it to the special software program that performs the analysis in order to determine the sensitivity levels.

This computer assisted system is capable of giving reliable tests and results. Generally the other components of the system include an artificial ear also called an acoustic coupler that responds to stimulus. This is used to measure the audio intensity after which every patient being evaluated can get assigned to their corresponding audio intensity level. Once the specialist has accomplished this they can then choose and fit the best set hearing aids on the patient.

Moreover included within this system is a microphone and head phones. These components enable the incoming sound to be captured and transmitted to the computer running special software. This computer can interpret this data appropriately. Generally this copies the working of a normal ear. Some cases may incorporate the use of an artificial mastoid that will generate stimulus in the same way the natural one does.

Ultimately an assessment of how much technology has contributed especially in the medical field shows very positive and considerable contributions. With devices like the audiometers patients can be evaluated to ascertain their hearing needs. After such a process these patients will be given effective solution that commonly involves the use of hearing aids.
