噪声利用,不知道大家有没有考虑这个问题?
通常情况下大家都是考虑如何介绍噪声的问题?不知道大家是否考虑过噪声利用的问题?不知道这方面有没有什么实质的利用?
有没有什么新的想法。 近几年出了本新书《振动利用工程》,我想噪声利用也是有的吧,只不过我们习惯视噪声为贬义的了。噪声正是因为已经被我们的耳朵接收,而且已经产生了不愉悦感,我们才说它是噪声的。如果要谈应用,也应该是声利用,而不是噪声利用。 噪声利用方面的文章,还真的没见到。下面这个大概能算一个:
“Sound induced vibration and duct noise control” (PhD Thesis, Hong Kong Polytechnic University). 该论文基本的思想是利用噪声诱发的结构振动抵消噪声。听起来有点像噪声主动控制,其实完全是被动控制,不需要任何外加的能量。所以,或许可以算作是声音利用的一个例子。
有一系列与该研究相关的论文可供查阅:
