dB meter - noise measure

Did just one measurement, then stopped working. Waist of money this one!

Seems good. I appreciate the option to calibrate the noise level (provided that you have a good instrument to calibrate it against). I suggest that the blue background is substituted with another colour; the visual impression is quite overwhelming. Maybe plain white would be a good alternative? In any case the contrast between the background color and the words written on this background is so poor that it is almost impossible to read the text.

界面很简洁，挺灵敏的

靠近麦克风吹气都有115db

比较准确的，而且还是免费的。

还不错，先试试！

体积小 无广告。

简洁大方实用，没有国产软件乱七八糟的功能，也没打垃圾广告，截至目前，仍是良心的app😂😂😂

没用任何用处。什么垃圾玩意儿？

试试看吧。
