An Audiometer is a special device which is used in evaluating hearing loss problems. Moreover, this device is used in in the general diagnosis of ENT problems. The instrument is uniquely calibrated to capture the exact data during hearing loss evaluation. The calibration is done in decibels as they are the standard units for measuring the intensity of sound. Calibration of this device needs to be done on regular basis. Doing this ensures that it gives error free results. Moreover, a good calibrated device will always give consistent results which can be trusted in analyzing hearing loss intensity of a patient.
The device does resemble a pair of headphones. However, it has several connections which include a special personal computer. Also embedded in this device is feedback control button. This button gives feedback signals to the PC whenever pressed. During operation, a patient is subjected to different audio frequencies which are from the audiometer. The patient then presses the button whenever they hear the sound. These different frequencies through which the patient is able to hear are than compiled to a data which is used to plot an audiogram.
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.
If you decide to shop for an audiometer, you will either go for the software or the hardware type. The software type is most common in homes and educational institutions. It uses special developed software which is installed in a computer. Data fed into this software gives the hearing range of the patient under test.
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 overall procedure of identifying a hearing loss problem is not complex as you might think. With this device, it is very easy.it only entails the patient being subjected to an audio from the device then their reaction at different frequencies being noted. These different frequencies give a range of the hearing capabilities of the patient. The range aid the medical specialist in treating such a 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.
An audiometer can also be used to diagnosis hearing problems in animals. Veterinary doctors do train the animals to react to these sound frequencies through different ways. They can train the animals to eat, raise special sound or behave anomaly whenever they hear such audio.
