Under experimental conditions, the masking effect of three types of music and of "white" masking noise was studied using a special speech-audiometric test (L. Tsaneva 1978, 1993). The signal-to-noise relation was found to be the most significant factor affecting spoken information perception, regardless of the type of music used as masking agent (level of correlation coefficients, jR = 0.89). The types of music used (modern, classical, playback) showed no appreciable differences in masking, remaining at the same time stronger masking factors compared to "white" noise. Conclusions were made as to hygienic-ergonomic aspects to be considered for intensity of musical programs in conforming with pertinent standards.
在实验条件下，使用一种特殊的言语听力测试（L. 察内娃，1978年，1993年）研究了三种类型的音乐以及“白”掩蔽噪声的掩蔽效果。结果发现，无论用作掩蔽剂的音乐类型如何，信噪比都是影响语音信息感知的最重要因素（相关系数水平，jR = 0.89）。所使用的音乐类型（现代音乐、古典音乐、重放音乐）在掩蔽方面没有明显差异，同时与“白”噪声相比仍是更强的掩蔽因素。得出了关于在符合相关标准的情况下音乐节目强度应考虑的卫生工效学方面的结论。
