Hearing test. A hearing test provides an evaluation of the sensitivity of a person's sense of hearing and is most often performed by an audiologist using an audiometer. An audiometer is used to determine a person's hearing sensitivity at different frequencies. There are other hearing tests as well, e.g., Weber test and Rinne test .
Absolute threshold of hearing. The absolute threshold of hearing ( ATH ), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the ...
Sensorineural hearing loss ( SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ ( cochlea and associated structures), or the vestibulocochlear nerve ( cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss. [citation needed] SNHL is usually permanent and can be mild, moderate, severe ...
1.33 billion / 18.5% (2015) [ 4] Hearing loss is a partial or total inability to hear. [ 5] Hearing loss may be present at birth or acquired at any time afterwards. [ 6][ 7] Hearing loss may occur in one or both ears. [ 2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties ...
95.41. MeSH. D001301. Pure-tone audiometry is the main hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss [1] [2] and thus providing a basis for diagnosis and management. Pure-tone audiometry is a subjective, behavioural measurement of a hearing ...
The observed vibrations were then converted into sound and the frequency was sped up so the noise would be audible to human ears. Listen to the ear-shattering noise in the video above, and feel ...
Psychoacoustic (or psychophysical) tuning curve test. Speech audiometry is a diagnostic hearing test designed to test word or speech recognition. It has become a fundamental tool in hearing-loss assessment. In conjunction with pure-tone audiometry, it can aid in determining the degree and type of hearing loss.
Audiogram. 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] The threshold of hearing is plotted relative to a standardised curve that represents 'normal ...
