摘要
一般的噪声测量都需要专业声级计,普通消费者一般不会购买声级计,为了能让普通人都能够了解周围的噪声情况,提出了一种利用手机进行噪声测量的方法,从手机测量噪声的原理分析了智能手机测量噪声的可行性,在测量有代表性手机的频率响应和级线性范围等基本性能的基础上,分析了手机测量噪声存在的问题。
Generally, noise measurement should use professional sound level meter, and ordinary customer would not buy it. In order that ordinary people have knowledge of noise level around, a measuring method by using smart phone is proposed, and the feasibility from the principle of measuring noise by smart phone is studied.Also, the existing problem based on the basic specifications of frequency response and level linearity range is analyzed.
