What Does an Audiometer Do?
If you've ever wondered what an audiometer does, you're not alone. The audiometer is an instrument used to measure your hearing ability. Hearing loss is a major cause of hearing loss, but there are many other health issues that may be contributing to your inability to hear. Whether you suffer from tinnitus or ringing in the ears, an audiometer can help you determine if you're at risk for hearing loss. These tests are conducted in a quiet room. You can use any kind of audiometer you're comfortable with and purchase, such as handheld screening audiometers or full diagnostic audiometers. These tests measure the frequency range between 500 and 4,000 Hz. To know more about audiometers, visit the Advent Ear website.
A typical audiometer consists of an embedded hardware unit that connects to headphones and a computer. It also features a feedback button for the test subject. Some audiometers also include bone vibrators, which are used to test conductive hearing mechanisms. A qualified audiometrist can use these devices to determine the patient's hearing impairment. A comprehensive evaluation of hearing is necessary to identify potential problems. A medical-grade audiometer uses pure tones to measure threshold sensitivity.
Audiograms measure the ability of a patient to hear tones between 250Hz and 8000Hz. Human speech falls in this range, so an audiogram tests a patient's ability to hear tones. An audiometer also performs other tests. Conditional play audiometry is used for children two to five years old, and conventional pure tone audiometry is used for adults. Conditional play audiometry is a more detailed test that assesses laterality.
Another useful feature of an audiometer is the frequency axis. The lowest frequency tested is 250 Hertz, while the highest frequency is 8000 Hertz. The range of pitch and loudness is similar to a piano keyboard. Most speech falls in this range, and the lowest frequencies are consonants and vowel sounds. A distorted audiogram can give an idea of how a person's hearing is affected.
In addition to the sensitivity test, an audiogram also measures auditory acuity. This measure is crucial for industrial workers. It allows the examiner to measure the level of sound a person can hear and then classify it as mild, moderate, or severe. This information is used to determine if the hearing conservation program a person is participating in is preventing the loss. If the results are positive, the audiogram will indicate whether the employer has adopted a hearing conservation program.
