The results are represented by an audiogram, and are usually interpreted by an audiologist, or a registered Medical Officer, [4] unless the audiometrist is also an audiologist, with the aim of diagnosing hearing loss. There are currently some misconceptions regarding the definition of Audiometrist and Audiologist, which vary from country to ...
Pure-tone audiometry provides ear specific thresholds, and uses frequency specific pure tones to give place specific responses, so that the configuration of a hearing loss can be identified. As pure-tone audiometry uses both air and bone conduction audiometry, the type of loss can also be identified via the air-bone gap.
A basic measure of hearing is afforded by an audiogram, a graph of the absolute threshold of hearing (minimum discernible sound level) at various frequencies throughout an organism's nominal hearing range. [4] Behavioural hearing tests or physiological tests can be used to find the hearing thresholds of humans and other animals.
Key Takeaways: An audiogram shows the softest sounds (volume: soft to loud) you hear at each frequency (low to high pitches). The lower the line on the graph, the worse your hearing is at that ...
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 ...
To take this into account, hearing sensitivity can be measured for a range of frequencies and plotted on an audiogram. Other method for quantifying hearing loss is a hearing test using a mobile application or hearing aid application, which includes a hearing test. [1] [2] Hearing diagnosis using mobile application is similar to the audiometry ...
An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer. The Y axis represents intensity measured in decibels (dB) and the X axis represents frequency measured in hertz (Hz). [ 1 ]
Portable audiometer Maico, circa 1960s. An audiometer typically transmits recorded sounds such as pure tones or speech to the headphones of the test subject at varying frequencies and intensities, and records the subject's responses to produce an audiogram of threshold sensitivity, or speech understanding profile.
