Audiometry
WHAT IS AN AUDIOMETRY?
An audiometry is the study that is carried out to determine the hearing level of people. That is, to know their ability to hear sounds.
Audiometry measures the frequency of intensity (or volume) in dB and also measures the speed of vibration of sound waves (or tone) in Hz.
The results of this test can identify whether the ears are suffering from hearing loss and the level at which they are suffering from it. Normal hearing values are always below 27 dB of intensity. Any value above 27 dB is considered abnormal. However, there are different levels of hypoacusis, being particularly severe from 75 dB.
Hearing loss is a fairly common problem among the population. It is usually the result of:
- Birth defects
- Chronic ear infections
- Exposure to loud noises on a regular basis
- Suffer damage to the eardrum or middle ear
- Diseases of the inner ear
- Genetic diseases
