Usually dichotic listening tests show a right-ear advantage for speech sounds. Right-ear/left-hemisphere advantage is expected, because of evidence from Broca's area and Wernicke's area, which are both located in the left hemisphere. In contrast, the left ear (and therefore the right hemisphere) is often better at processing nonlinguistic ...
These are the Randomized Dichotic Digits Test [33] and the Dichotic Words Test. [34] Older dichotic listening tests that provide normative information for the right and left ears can be used to supplement these two tests for support of the diagnosis ([1]). If performance across two or more dichotic listening tests is normal in the dominant ear ...
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.
Both come with a complete hearing aid set for the right and left ear and a charging case. The premium package also includes three years of audiology support, a better warranty, and damage and loss ...
HRTF filtering effect. A head-related transfer function (HRTF) is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others.
The automatic response involves the MOC efferents inhibiting the output of the cochlear of the left ear. The output of the right ear is therefore dominant and only the right hemispace streams (with their direct connection to the speech processing areas of the left hemisphere) travel up the auditory pathway.

In 1885, Arthur Hartmann designed an "Auditory Chart" which included left and right ear tuning fork representation on the x -axis and percent of hearing on the y-axis. In 1899, Carl E. Seashore Prof. of Psychology at U. Iowa, United States, introduced the audiometer as an instrument to measure the "keenness of hearing" whether in the laboratory ...
