An audiometer is a medical device found in most clinics, hospitals and audiology centers. Its use is to determine the hearing loss intensity of patients. Generally, the device can be used by E. N. T specialist in diagnosing various problems. The standard measurement unit for this device is the decibel. It is a unit which is universally accepted to measure the intensity of sound.
The audiometer resembles a pair of headphones. It is connected to a computer which controls its operation. A special button, which gives feedback signals as received from the patient, is also embedded in the device. During operation, the response of a patient to different frequencies is displayed in the computer which is subsequently used to plot an audiogram. The audiogram is keenly analyzed to determine the range which a patient can react to different sound frequencies.
An audiogram is simple graph showing the intensity of the sound in decibels versus the frequency in hertz. It gives a representation of the audible threshold of a patient under test exactly as it is being measured by the audiometer. When constructing an audiogram, the specialist takes into consideration the fundamental frequencies, as they must be included the audiometer readings. Normally, a range of 100HZ to 8000Hz is considered to be the range in which an audiogram can be constructed.
There are two types of audiometers found in the market. These are the hardware and the software types. The two types are closely related though they vary in cost and efficiency. The software type is not very sophisticated. It is the one found in several homes as it is easier to use. It only requires a computer program to display its results.
Hardware devices on the other contain an embedded unit which is connected next to the headphones. This unit is linked with a special button which gives feedback signal to the device during operation. This device is relatively expensive than the software type as it gives results of higher accuracy. They are very efficient in hearing loss tests.
The hearing loss procedure is diagnosed by presenting a patient with a sound from the audiometer but being varied in frequency. Their reactions to this sound of different frequencies will be noted down. It is these frequencies which are used to plot the audiogram. The medical specialist will then study the audiogram to determine the intensity of hearing loss of the patient.
An adult person will show a reaction to certain frequencies by pressing a button which is usually embedded to the device. For small children, their reaction is normally different. Their response can be a head turn or by pressing a toy which is usually provided during the test.
Hearing loss problems are not suffered by human beings. Animals do also suffer from this problem. An audiometer is still the device veterinary doctors determining the hearing capabilities of animals. The animals are trained to respond to the sound through several practices like providing them with food, water e. T. C whenever they react to such audio frequencies.
