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 basically a graph of the intensity of the sound in decibels against the reaction frequency in hertz. This graph is drawn with the aid of a computer. The graph will then be analyzed carefully by a medical specialist to determine at what range the patient is able to react to the sound frequencies. This will guide the specialist in administering treatment to the patient.
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.
During hearing loss diagnosis, the audiometer presents a sound to a patient which is then subjected to different frequencies. The reaction of the patient to this sound will be displayed in the computer. The doctor will vary this sound continually until they are satisfied that a complete hearing loss analysis is conducted. They will then construct an audiogram based ion these readings. The graph will then be analyzed to determine the range of frequencies where the patient is reacting to the sound. A headphone is provided to the patient to shield them from external disturbances.
If the patient under test is an adult, then the hearing loss analysis is very easy. They will be instructed to press the feedback button whenever they hear the audio. For children, it is very different. Only their reaction in whatever manner is required. The kid can be instructed to press a toy whenever they hear the audio. The frequency is then noted down.
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.
