人们越来越关注保护安静和宁静的地区免受侵入性噪音的影响。减少噪音来源和设置屏障以防止噪音传播是经常考虑的缓解措施。另一种方法是试图掩盖或分散注意力远离噪音源。掩蔽或分散注意力的声源应该是令人愉快的，这样它就不会增加单独由噪声源引起的任何刺激。本文所述的实验室测量包括在受控条件下捕获水落在水、砾石、砖块和小石块以及各种组合上的第三倍频程谱。然后将这些频谱与典型的交通噪声频谱进行匹配，以评估每个选项的掩蔽程度。在每次测量过程中也进行了录音，这些录音后来被用来对声音的平静度进行主观评估。研究发现，水声在掩蔽和对平静的主观影响方面都存在差异。
There is increasing concern with protecting quiet and tranquil areas from intrusive noise. Noise reduction at source and barriers to transmission are mitigation measures often considered. An alternative is to attempt to mask or distract attention away from the noise source. The masking or distracting sound source should be pleasant so that it does not add to any irritation caused by the noise source alone. The laboratory measurements described in this paper consisted of capturing under controlled conditions the third octave band spectra of water falling onto water, gravel, bricks and small boulders and various combinations. These spectra were then matched with typical traffic noise spectra to assess the degree of masking that could be expected for each option. Recordings were also taken during each measurement and these were used later to enable the subjective assessment of the tranquillity of the sounds. It was found that there were differences between water sounds both in terms of masking and their subjective impact on tranquillity.
