The paper discusses the characteristics of spatial electromagnetic noise generators, as well as the formation of a broadband noise signal. A number of well-known methods for assessing the quality of masking noise interference and the approaches used in them have been described. Approaches to the measurement of masking noise were also determined in assessing their quality. In conclusion, additional methods are proposed for assessing the quality of masking noises, such as searching for correlation of noise in different frequency sub-bands and using statistical and (or) graphical methods (tests) for randomness.

People with hearing impairments experience a reduction in speech intelligibility in noisy surroundings. The extent of this reduction depends on the degree of impairment in the temporal resolution of the patient's ear, too. The change of the speech intelligibility of hearing-impaired people was investigated in the presence of different masking noises, especially when using hearing aids with adjustable attack (AT) and release (RT) times within same frequency bands.
