The most common hearing test used, pure tone audiometry, is generally used to test one or two frequencies within an octave, from 0.5-8 kHz. More sensitized

An audiogram represents an individual’s hearing ability by frequency (pitch) and intensity (volume). The softest sounds that a person can hear at a particular frequency is called their hearing threshold. This is usually represented by markings on their graph; red represents the right ear and blue represents the left.

For more information or Degrees of hearing loss means the severity of the hearing loss that the individual experiences. The levels of hearing loss are generally classified as mild, moderate, severe or profound. Hearing loss that borders between two categories is typically described as a combination of the two categories (for example, thresholds at 60 dB HL might be called moderate-to-severe).

An audiogram is an important part of your comprehensive hearing test - and a key to our understanding of the health of your ears. Essentially, it can be best understood as a visual representation of your hearing. It graphs how it may (or may not) differ from the normal hearing range, by showing your hearing threshold levels at different

The pictures and letters in the chart above represent a normal hearing range at different volume and pitch levels. These range from very soft, like a whisper, to very loud, like a plane. When you look at an audiogram, you’ll see a graph with various lines and symbols. Each one represents a measurement of hearing:

After that point, people will usually begin to display some communication When all hearing levels or the hearing levels at some pitches fall outside the normal range, particular speech sounds can be difficult to hear, which can affect the hearing test that measures a person's ability to hear different Normal hearing range is.

The audiogram illustrates your hearing by representing your hearing threshold levels at different frequencies. The hearing threshold levels show the point at which a tone can be perceived. A hearing threshold level of between 0 and 25 dB is normal. This means 0 dB for a …
