Abstract

Recently in Japan, noise from wind turbines and domestic heat sources have caused an increase in noise annoyance due to their low-frequency tonal components. The purpose of this study is to investigate the effects of tonal components on the loudness of environmental noise. An auditory test was conducted to evaluate the loudness of the tonal noise using an adjustment method. The stimuli were composed of a broadband noise and a low-frequency tonal component. For the tonal noises, a pure tone was added to the noise. The frequency of the tone was either 40, 50, 100, or 200 Hz. The tonal audibility was either 0, 5, or 15 dB. Loudness was evaluated using the A-weighted sound pressure level (L_A) and the loudness levels according to the Zwicker loudness model and the Moore and Glasberg loudness model. The results show that the increase in loudness depends on the spectrum of the background noise and tonal frequency. When tone was added to low-frequency dominant noise, the L_A may not fit the psychological loudness of the stimuli used in our experiment.

对含有低频音调成分的噪音响度的主观评价

最近，在日本，风力涡轮机和家用热源的噪声因其低频音调成分而导致噪声烦恼增加。本研究旨在调查音调成分对环境噪声响度的影响。我们采用调整法进行了听觉测试，以评估音调噪声的响度。刺激物由宽带噪声和低频音调成分组成。对于音调噪声，噪声中加入了一个纯音。音调的频率为 40、50、100 或 200 赫兹。音调可听度为 0、5 或 15 分贝。响度使用 A 计权声压级（LA）进行评估，并根据 Zwicker 响度模型和 Moore 与 Glasberg 响度模型评估响度级别。结果表明，响度的增加取决于背景噪声的频谱和音调频率。当在低频主要噪声中加入音调时，LA 可能与我们实验中使用的刺激物的心理响度不符。

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
