Audiometers are tools primarily used to evaluate hearing problems. These equipments are commonly found in audiology clinics. These devices usually consist of hardware that is connected to a set of headphones. There is also a button intended for the subject. Now that technology is advanced, these devices can be operated with computers. Standards are set for these test procedures.
As this field has developed over the years, different variations of the devices have been made. One type of the device is clinical PC based. These are more accurate when testing hearing problems. These types are generally used in hospitals, diagnostic centers, and research studies. Another type is the screening PC based which can be used by anyone in their own homes to test hearing.
With their important function, the devices should be calibrated routinely. This is necessary to make sure the levels on the display are always equivalent to the stimulus that the patient is exposed to. With proper calibration, the measurements will be consistent and the results will be accurate. An audiometric calibration system used to do the calibration.
To test air conduction hearing, a system that includes an ear simulator is used. For this system, an artificial ear calibrates air conduction. Headphones will be applied to the open side of the coupler. There is an internal microphone that detects sound pressure level within the cavity. Outputs will be measured by a sound level meter.
Bone conduction hearing can be tested with an artificial mastoid. The device can calibrate bone conduction channel of audiometers. This is used to test hearing as response to bone conduction mechanisms. The tool has a dome which represents the human mastoid. A transducer measures the force applied and the output is measured by a sound meter.
Various models of these equipments are now used. These models have certain specifications that make them suited for specific applications. Now that these equipments are available, it is easier for physicians to diagnose hearing problems. Special equipments would be needed to perform some diagnostic procedures. This field in medicine has greatly benefited from these tools.
Since various types are now available, hearing specialists will be able to find their choice of equipment. There are stand alone types which are often used for screening. Some are also computer based which are commonly used for diagnostic purposes. Each of these equipments have different intensities and frequencies depending on the exact application these are designed for.
Diagnostic equipments must be fully operational and efficient all the time. Accuracy is one important factor that these devices must have in order to provide reliable measurements. Results must be accurate to establish proper diagnosis of one's hearing loss. Specialists need to determine the extent of hearing damage so they can also recommend appropriate management.
Hearing specialists already know the significance of audiometers in their field. Physicians should have appropriate equipment in their clinics in order for them to do their job correctly. They must have the right equipment to provide quality services and better treatment to patients. A hearing condition can be managed effectively if the patient is correctly diagnosed.
