Method of Evaluating the Quality of Masking Noise

Effective protection of confidential information by using masking noise generators is quite an important task for most government and commercial institutions. However, there is currently no common approach to the assessment of the quality of voice information noise masking and the existing techniques require major improvements. The article presents a modified method of evaluating the quality of noise used for masking voice information. This methodology based on the entered uniformity parameter of amplitude spectrum allows one to consider and calculate the degree of failure in the frequency domain of the noise signal.
