Audiometers are devices used to evaluate hearing loss. These are standard equipments found in audiology centers. Such devices typically consist of hardware connected to a pair of headphones and a button for the test subject. With advances in technology today, some of these devices are controlled by computers. There are certain standards set for the test procedures.
There has been a lot of developments in the field over the years. Different devices are now used for certain purposes. One type that can be used at home is called a screening PC based which people can use to test their own hearing. A more accurate type is the clinical PC based which is used in hospitals, clinics, as well as research facilities.
These equipments must be calibrated routinely to make sure that levels on display are equal to the stimulus the patient is subjected to. Proper calibration ensures that measurements are always consistent and results are accurate. The devices are calibrated using audiometric calibration system. When it comes to diagnostic tools, accuracy is very important.
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.
On the other hand, bone conduction hearing is tested using an artificial mastoid. Such device calibrates the bond conduction channels of audiometers. Bone conduction mechanisms can be used to test hearing. This device has a dome shaped part which emulates a human mastoid. The force applied is measured by a force transducer. A sound meter also measures the output.
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 should always be fully functional and working efficiently. Accuracy is a very important quality of these devices to make sure they provide reliable measurements. Accurate results are necessary to create a correct diagnosis of one's hearing problems. Specialists would need to know the extent of the patient's hearing loss to determine what type of management would be effective.
Hearing specialists know the importance of having audiometers in their facilities. Physicians must have the kind of equipment needed for them to perform their duties. Proper equipments are necessary to they can provide quality treatments and better services. Patients can be given appropriate management if they are accurately diagnosed. This gives them a better chance at recovery.
