Those additional tests will be discussed in the brochures that deal with each of those topics. Most of these tests are done in a sound treated room or booth, but testing may be done in other areas if proper precautions are taken to reduce the room noise. Tone Tests 2. Speech Tests 3. We will now explain each of these areas in more detail, however we will continue to use understandable terms if at all possible.
Low frequencies are lower numbers and high frequencies are higher numbers.
Tone tests have 2 parts, air conduction and bone conduction. This level is called the threshold. Bone-conduction tone tests evaluate only the inner ear and the hearing nerve and are done if the air conduction tests revealed a hearing loss. The patient has a small bone-conduction vibrator placed on the bone directly behind the ear and the sound from the audiometer is sent through the bone vibrator instead of the headphones. The patient is tested for threshold at each of the frequencies again.
