soundproofing for urban people

 Frequency matters When you're dealing with a noise issue, the frequency of that noise is just as important as the decibel level. A decibel is the loudness of the sound, and measuring decibels can alert you when a sound is more than just a nuisance, but dangerous to your health. However, decibel levels on their own don't tell the whole story. The frequency of the sound is also very important. The frequency is a measure of how many sound waves per second are produced by a sound, and determines its pitch. A low-frequency sound might be really annoying, but it might not be that loud. The lower frequencies are typically below 150 Hz, and often sound like a deep bass sound that's not necessarily loud, but the vibrations from that sound can travel through the entire frame of a building and disrupt sleep or cause stress. Knowing both the decibel level and the frequency of an unwanted sound can help you determine the right soundproofing solution. For example, a low-frequency nois

For a quick lesson on how to use the NIOSH (National Institute of Occupational Safety and Health) app to measure decibels and noise, check out my latest Soundproofist  video. This handy app is free, although only available for iOS devices right now. It's a great app to use if you want to measure average and maximum noise levels with either A-weighted or C-weighted decibels. You can save each measurement as a report.
