Purpose

Road traffic noise is the most common source of noise in modern cities. The noise indicators used to manage noise do not take into account its temporal structure. However, in cities the traffic flow varies during the day, peaking due to congestion and more fluent periods. In this research we sought to analyze how people (giving answers on a numerical ICBEN scale) perceive noise stimuli with the same LAeqT values but different time structures (more/less noise events, different amplitude envelopes).

Methods

31 people with normal hearing took part in an experiment conducted in an anechoic chamber. Participants listened to 18 different noise recordings and rated each of them using the numerical ICBEN scale regarding noise annoyance.

Results

The results showed that only sound level was a statistically significant factor. However, based on people’s remarks about noise, we can also say that the more intermittent the noise is, the more negative feelings it evokes in people.

Conclusions

Time structure does not have a significant influence on people’s judgments about noise annoyance. However, people tend to have a preference for a steady noise rather than an intermittent one.

信号的时间结构对道路交通噪声感知噪声的影响

目的

道路交通噪声是现代城市中最常见的噪声源。用于管理噪声的噪声指标未考虑其时间结构。但是,在城市中,白天的交通流量会有所变化,由于交通拥堵和交通更加顺畅,交通流量达到顶峰。在这项研究中,我们试图分析人们(以数字ICBEN量表给出答案)如何感知具有相同L AeqT值但具有不同时间结构(更多/更少的噪声事件,不同的幅度包络)的噪声刺激。

方法

31名听力正常的人参加了在消声室内进行的实验。与会者聆听了18种不同的噪音记录,并使用有关噪音烦恼的ICBEN数字量表对每个录音进行了评分。

结果

结果表明,只有声级才是统计学上显着的因素。但是,根据人们对噪音的看法,我们也可以说,噪音越断断续续,就会给人带来更多的负面感觉。

结论

时间结构对人们对噪声烦恼的判断没有重大影响。但是,人们往往更喜欢稳定的声音,而不是间歇性的声音。
