Here's how to read an audiogram and a doctor's explanation of the most common results including sloping hearing loss, notched hearing loss, cookie-bite hearing loss and reverse-sloping hearing loss.
The results of pure-tone audiometry are however a very good indicator of hearing impairment. Hearing disability is defined by the WHO as a reduction in the ability to hear sounds in both quiet and noisy environments (compared to people with normal hearing), which is caused by a hearing impairment. [ 17 ]
For example, aging typically leads to hearing thresholds which get poorer as test frequencies get higher. [10] Noise induced hearing loss is typically characterized by a "notch" in the audiogram, with the poorest threshold occurring between 3000 and 6000 Hz (most often 4000 Hz) and better thresholds at lower and higher frequencies. [11]
The result of the test is an audiogram diagram which plots a person's hearing sensitivity at the tested frequencies. On an audiogram an "x" plot represents the softest threshold heard at each specific frequency in the left ear, and an "o" plot represents the softest threshold heard at each specific frequency in the right ear.
Minimum audibility curve is a standardized graph of the threshold of hearing frequency for an average human, and is used as the reference level when measuring hearing loss with an audiometer as shown on an audiogram.
The result of most audiometry is an audiogram plotting some measured dimension of hearing, either graphically or tabularly. The most common type of audiogram is the result of a pure tone audiometry hearing test which plots frequency versus amplitude sensitivity thresholds for each ear along with bone conduction thresholds at 8 standard ...
The speech banana is a banana-shaped region where the sounds of human languages appear on an audiogram. (An audiogram is a graphical representation of someone's ability to hear over a range of frequencies and loudness levels. Hearing on an audiogram is displayed as frequency in Hertz on the x-axis and loudness in decibels on the y-axis.)
For example, A S (a shallow tympanogram) will show a stiff middle ear system or A D (a deep tympanogram) consistent with ossicular discontinuity or a monomeric membrane. Only measures of static acoustic admittance, ear canal volume, and tympanometric width/gradient compared to sex, age, and race specific normative data can be used to somewhat ...
