A Look Into The Features Of An Audiometer

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.

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.

The hardware type is a bit complex. It requires an experienced person to use it. It comes with an embedded control unit and a feedback button as well. It requires a special type of a computer application to display its results. This device is relatively expensive. It is found in referral hospitals and research labs.

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.

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.
