There are many different types of an audiometer, ranging from the most basic to the most sophisticated. The difference between these types is primarily in their level of sophistication, which increases from the screening type to the clinical type. While the distinctions between the different types of audiometers are often blurred in practice, there are certain factors that define each type.
For example, the frequency accuracy of an audiometer and the range of hearing levels it is capable of measuring are key factors that affect its classification. ANSI and ISO have published guidelines for minimum features of audiometers, and these are usually in close agreement. Nowadays, the most popular type of audiometer used by doctors is a portable audiometer. As the name goes, these systems are portable. You can get more information about these systems on the Advent Ear website.
When choosing an audiometer, you should consider the type of hearing test you'll be undergoing. Most audiometers are manual and do not connect to patient information management systems. To connect these devices, a tablet and screenless audiometric testing device must be used. This is generally a more expensive option. However, there are a number of touchscreen audiometers on the market, including the Audixi 10. The Audixi 10 offers a combination of portability and internet connectivity as well as an instant metrological calibration system, which eliminates downtime and reduces maintenance costs.
Another type of audiometer uses pure tone to test people's ability to detect different pitches. The test subjects will be asked to wear headphones and sit in a booth specially designed for hearing testing. A series of tones will be played through the audiometer, which they are instructed to listen for and repeat back. This information will be recorded on a chart called an audiogram. A comprehensive test like this is required for accurate diagnosis.
Bekesy audiometry is another type of audiometer. This type of audiometer relies on the listener's ability to control the intensity of sound waves as they change frequency. The Bekesy type is fast, reliable, and widely used in industrial and military contexts. Objective audiometry, on the other hand, is based on electrophysiologic and physical measurements and does not rely on the subjective responses of the subject.
Comprehensive audiometry includes different types of tests. The most basic type, known as behavioral audiometry, involves listening to various kinds of sounds and watching the behavior of the listener. It involves hearing sounds at various intensities, including low bass tones and high-pitched tones. The test may be routine screening or a response to a noticeable loss of hearing. If the test is completed correctly, the result will show whether you can recover the hearing you've lost.
