The article deals with results of experimental study comparing effects of 4 types of acoustic load--noise (constant and impulse) and music (electronic symphonic one and rap)--on hearing sensitivity, processes in nervous system and subjective evaluation. All types of acoustic load were equal in energy (on evaluation according to equivalent level during the experiment). The study included 2 levels of load--90 and 95 dB. The differences revealed demonstrate importance of impulse parameters of noise and musical load for reactions of acoustic analyzer and central nervous system. The experiments show that evaluation of harm caused by temporary and impulse noises should be based not only on assessment of specific (hearing) function, but also on parameters of central nervous system state. The authors found that music of certain acoustic and informational parameters may harm hearing function.
本文探讨了比较4种类型的声学负荷——噪声（恒定噪声和脉冲噪声）以及音乐（电子交响乐和说唱音乐）——对听力敏感度、神经系统过程和主观评价影响的实验研究结果。在能量方面（根据实验期间的等效水平评估），所有类型的声学负荷均相等。该研究包括90分贝和95分贝两个负荷水平。所揭示的差异表明，噪声和音乐负荷的脉冲参数对听觉分析仪和中枢神经系统的反应具有重要意义。实验表明，对暂时性和脉冲性噪声造成的危害进行评估时，不应仅基于特定（听力）功能的评估，还应基于中枢神经系统状态的参数。作者发现，具有某些声学和信息参数的音乐可能会损害听力功能。
