Patients who suffer from a tumor in or around the ear may undergo audiometry testing to decide whether a hearing loss has occurred or to monitor their hearing before and after surgery.
The most widely recognized sort of hearing test is known as Pure Tone Audiometry (PTA). The point of this test is to build up the quietest sounds you can hear at various frequencies or pitches. But the question asked by a patient is how long audiograms hearing tests takes around and the answer is, the test takes around 20 minutes.
The amount of hearing loss (or degree) is based on hearing sensitivity of a person’s experience. To determine the loss of hearing of a person, their hearing limits should be set. An auditory threshold is defined as a minimum level of sound that can be heard 50% of the time. Decibel (or DB) is a unit of intensity that is used to describe hearing sensitivity. During the diagnostic hearing evaluation, the threshold is measured at different frequencies (or Hertz, Hz) in each ear.
Procedure for Audiogram Tests
- The audiologist will bring you into a unique soundproof booth or a quiet room in which the test will happen.
- You will have a couple of earphones, put over your ears and also you will be given a unique handset with a reaction catch on it.
- Your audiologist will play you a progression of sounds through these earphones. The sounds will be played into one ear at any given moment as it were.
- Your audiologist will educate you to press the reaction catch at whatever point you feel that you hear a sound in your earphones, and to hold the conservative for whatever length of time that you can hear the sound – just relinquish the catch when you think the sound has halted.
- Each time you accurately hear the sound, the audiologist will decrease the volume marginally, until the point says that you are never again ready to hear it. The audiologist will then make a note of the quietest volume at which you could hear the sound.
Your listening ability test results will be recorded on an audiogram outline.
The audiogram is a diagram that tells clinicians precisely how well you can hear tones of various frequencies.
There will be a progression of images over the diagram. The situation of these images on the graph shows the quietest sounds you can hear at various frequencies. And show the degree of hearing loss.

What happens during the test?
Generally, Audiometry tests are organized in a quiet soundproofing room. Earphones will be placed on your head. You will be asked to talk and not sit down. Earphones are attached to a machine that will distribute your ears, and different sounds in one ear at a time. When you hear the sound, the audiologist will ask you to raise your hand.
For example, if you hear a sound from your left ear, lift your left hand up; If you hear a voice with your right ear, then lift your right hand. In some features, you may be asked to push a button or make some other signals that you have recognized the sound. An audiologist will record each tone in the least possible amount that you were able to hear it. Before or after the normal audiometry test, tuning forks are also used to conduct Rinne and Weber tests. Each test evaluates the ability of various types of hearing loss.
To assess speech discrimination, you will be instructed to repeat the words that you listen to. You will hear a series of two-syllable words on a volume which gradually decreases with the increase of the test. However, In the second phase of the test, you will hear and repeat a series of one-syllable in a quantity which does not change.
During the tympanometry and acoustic reflex test, a soft plug is placed in your ear. The plug will change the pressure and it will make a loud sound, and track its reactions to sound and various pressures. The movements of the eardrum are measured and at the same time, it is associated with the reflexes of small muscles.
Learning to read lips may assist you to realize what people are saying better. This test gives the audiologist information as to what can be accomplished with growth and what level of improvement could be made to your hearing.
