In music, ear training is the study and practice in which musicians learn various aural skills to detect and identify pitches, intervals, melody, chords, rhythms, solfeges, and other basic elements of music, solely by hearing.
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.
The second phase used the test to run and evaluate in a computer simulation analysis. [10] Lastly, in the third phase the test was field-tested on the PLATO computer system, and showed that it required an average tonal memory test scores of 6.05, 8.55, and 11.60 items to reach reliabilities of .80, .85, and .90 (4).

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.
It is also used in various kinds of audiometry, including pure tone audiometry, and the standard hearing test to test each ear unilaterally and to test speech recognition in the presence of partially masking noise. Auditory masking is exploited to perform data compression for sound signals .
A pure tone audiometry hearing test is the gold standard for evaluation of hearing loss or disability. [medical citation needed] Other types of hearing tests also generate graphs or tables of results that may be loosely called 'audiograms', but the term is universally used to refer to the result of a pure tone audiometry hearing test.

The first research on the topic of how the ear hears different frequencies at different levels was conducted by Fletcher and Munson in 1933. Until recently, it was common to see the term Fletcher–Munson used to refer to equal-loudness contours generally, even though a re-determination was carried out by Robinson and Dadson in 1956, which became the basis for an ISO 226 standard.
