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 resembles a pair of headphones but is fitted with a feedback button which is controlled by a computer. The computer helps the specialist conducting the hearing loss analysis to display the data which is eventually used to form an audiogram. This audiogram is the one used to analyze the range through which a patient can react to given sound frequency.
The audiogram is plotted with the intensity of sound as the y axis in decibel units and the frequency of sound in the x- axis in hertz. The measured reading of the patient will be noted down and used to plot such a graph. Usually, the specialist uses computer software to aid them in drawing a perfect graph. They feed the reading to the computer software which automatically plots the audiogram graph. An important frequency known as the fundamental is included in the data as it is being fed to software to ensure the resulting audiogram captures all the details of the patient.
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.
This hearing loss test using an audiometer can also be extended to animals. Vet doctors have devised unique ways to make sure that animals do respond to various frequencies. For instance they can provide food to the animal as way of rewarding it for responding to a certain frequency. The animal will be trained to understand that its response to a given frequency usually means food and therefore the doctor will be able to record down the range through which the animal can respond to different frequencies.
