论文摘要
在野生动植物摄影中，接近鸟类是一个巨大的挑战。如果设计正确，则鸟类摄影百叶窗可能是最有效，最不侵入性的方法。但是，到目前为止，百叶窗的声学设计已被忽略。在本文中，我们提出了降噪百叶窗，允许在近距离拍摄鸟类。首先，我们在中国云南的生态旅游中心进行问卷。因此，我们确定了观鸟者对室内声音环境的期望。然后，我们确定不同的变量，以检查建筑和声学决策对噪声传播的影响。最后，我们通过考虑鸟类的听力阈值来检查百叶窗的声学性能。数值模拟是在comsol多物理学的声学模块中进行的。我们的研究表明，摄影百叶窗需要针对人和鸟类健康的强烈而彻底的声学设计。
Getting close to birds is a great challenge in wildlife photography. Bird photography blinds may be the most effective and least intrusive way if properly designed. However, the acoustic design of the blinds has been overlooked so far. Herein, we present noise-cancelling blinds which allow photographing birds at close range. Firstly, we conduct a questionnaire in the eco-tourism centre located in Yunnan, China. Thus, we determine the birders' expectations of the indoor sound environment. We then identify diverse variables to examine the impact of architectural and acoustic decisions on noise propagation. Finally, we examine the acoustic performance of the blinds by considering the birds' hearing threshold. The numerical simulations are performed in the acoustics module of Comsol MultiPhysics. Our study demonstrated that photography blinds require a strong and thorough acoustic design for both human and bird well-being.
