soundproofing for urban people

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.

It will not eliminate low-frequency engine noise that penetrates your building frame, such as construction equipment or large truck engines. Here's how you can remedy this echo situation.
