Hearing test are accurate and painless and they are used to measure what sound you can and cannot hear. The results are marked on an audiogram – a device that shows how loud are the sounds so you can hear them. The loss of hearing is measured with dB (decibels) which measure the intensity and pitch in Hz (hertz) which measure the frequency. According to these measurements, the hearing loss will be described as mild, moderate, severe or profound.
There are different hearing test that can be used to tested the hearing loss in adults and children.
- The simplest and most common way to test the loss of hearing is known as pure tone audiometry. This procedure includes listening to a wide range of pure tones such as whistles and beeps.
- The process when the hearing is measured by listening pure tones through headphone is known as air conduction. The sounds are transmitted via the air down the canal of the ear, then going through the middle ear and the last station is the delicate cochlea in the inner ear.
- Bone conduction test is made by using a small vibrator which is placed behind the ear. This way sound to travel through the bones to the cochlea and hearing nerves to the middle ear.
