Sound is the perceptual result of mechanical vibrations traveling through a medium such as air or water. Through the mechanisms of compression and rarefaction, sound waves travel through the air, bounce off the pinna and concha of the exterior ear, and enter the ear canal.
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
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.
The hearing ability of a dog is dependent on breed and age, though the range of hearing is usually around 67 Hz to 45 kHz. [22] [23] As with humans, some dog breeds' hearing ranges narrow with age, [24] such as the German shepherd and miniature poodle. When dogs hear a sound, they will move their ears towards it in order to maximize reception.

A hearing loop consists of one or more physical loops of cable which are placed around a designated area, usually a room or a building. The cable generates an electromagnetic field throughout the looped space which can be picked up by a telecoil-equipped hearing aid, a cochlear implant (CI) processor, or a specialized hand-held hearing loop receiver for individuals without telecoil-compatible ...
The accuracy of tempo within an auditory image usually suffers when recalled; however, the consistency of a person's perception of tempo is preserved. When surveying subject's auditory imagery, their sense of tempo usually stays within 8% of the original tempo heard in a song that the subject heard at some point in the past. [1]
