   The auditory brainstem response ( ABR ), also called brainstem evoked response audiometry ( BERA) or brainstem auditory evoked potentials ( BAEPs) or brainstem auditory evoked responses ( BAERs) [ 1][ 2] is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp.

3. Lip reading - Wikipedia

   en.wikipedia.org/wiki/Lip_reading

   Lip reading, also known as speechreading, is a technique of understanding a limited range of speech by visually interpreting the movements of the lips, face and tongue without sound. Estimates of the range of lip reading vary, with some figures as low as 30% because lip reading relies on context, language knowledge, and any residual hearing. [1]

4. Rinne test - Wikipedia

   en.wikipedia.org/wiki/Rinne_test

   The Rinne test ( / ˈrɪnə / RIN-ə) is used primarily to evaluate loss of hearing in one ear. [ 1] It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid. Thus, one can quickly screen for the presence of conductive hearing loss. [ 2]

5. Visual reinforcement audiometry - Wikipedia

   Visual reinforcement audiometry ( VRA) is a key behavioural test for evaluating hearing in young children. [1] [2] First introduced by Liden and Kankkunen in 1969, VRA is a good indicator of how responsive a child is to sound and speech and whether the child is developing awareness to sound as expected. Performed by an audiologist, VRA is the ...

6. Absolute threshold of hearing - Wikipedia

   en.wikipedia.org/wiki/Absolute_threshold_of_hearing

   Firstly, the test defines the stimulus and specifies the manner in which the subject should respond. The test presents the sound to the listener and manipulates the stimulus level in a predetermined pattern. The absolute threshold is defined statistically, often as an average of all obtained hearing thresholds. [4]

8. Perception of infrasound - Wikipedia

   en.wikipedia.org/wiki/Perception_of_infrasound

   Perception of infrasound. Infrasound is sound at frequencies lower than the low frequency end of human hearing threshold at 20 Hz. It is known, however, that humans can perceive sounds below this frequency at very high pressure levels. [ 1] Infrasound can come from many natural as well as man-made sources, including weather patterns ...
