About Fdit Wall Mounted Decibel Meter, Digital Sound

【 Why do we need a decibel meter】 What can we do to take precautions against noise when we start to renovate our apartment? Of course, we are worried it will noise our neighbors. To be a civilized citizen, a precise sound decibel meter should be put to use and wall mounted by us. It has 4 mounting holes on the rear for wall mounting. It fixed well on wall. No need to be handheld everywhere. When the community council complained, you only have to show them that the noise meter had not exceeded the decibel level. The sound level meter is a professional noise decibel that it can be counted on, though it comes directly from Chinese factory.
