摘　　要：鸟鸣声作为城市绿色空间中生物声景的主导成分之一,对减缓城市居民压力起到关键的作用。本研究目的在于探究城市公园中鸟鸣声持续时间对交通声造成心理压力的恢复作用以及鸟鸣声驱动因素与交通噪声烦恼度的内在联系。以加拿大温哥华市的3个城市公园为例,对41个观测点进行实验研究。通过让受试者先后倾听交通噪声和鸟鸣声,比较受试者交通噪声烦恼度的数值变化。研究结果表明:1~4 kHz的倍频带频率与鸟鸣声持续时间以及交通噪声烦恼度具有较强的相关性;持续时间超过20秒的鸟鸣声均可降低交通噪声烦恼度,但超过120秒后效果将减弱;鸟鸣声持续时间达到60秒和80秒时效果最优,交通噪声烦恼度减缓率可达26.67%和22.22%。在实际应用中可增加浆果类植物吸引鸣禽,并增设可调控时长的鸟鸣声播放设备,以期有效降低城市公园交通噪声烦恼度。As an important part of the sensory soundscape of urban parks,birdsong plays a key role in reducing the stress of urban residents.The purpose of this study is to explore the influence of the duration of birdsong on traffic noise annoyance in urban parks and the relationship between the traffic annoyance and the birdsong.Taking three urban parks in Vancouver of Canada as an example,questionnaire investigation and acoustic measurement were conducted at 41 observation points.Let the participants listen to traffic noise and birdsong in sequence,then the variation of the traffic annoyance were compared and analyzed.Result show that there is a strong correlation among the sound frequency of 1 to 4 kHz,the traffic annoyance and the duration of birdsong soundscape.Birdsong can reduce traffic annoyance when the duration of birdsong is between 20 seconds and 120 seconds.When the duration of birdsong reaches 60 seconds and 80 seconds,the effect of the annoyance reduction is optimal,and the decline rates of traffic annoyance can reach 26.67%and 22.22%respectively.However,when the duration of birdsong exceeds 120 seconds,the effect of annoyance reduction will decrease.In practical applications,more berry plants can be applied to attract songbirds.In addition,birdsong players can be used to adjust the duration and frequency of the birdsong,so as to reduce the traffic annoyance in urban parks.
