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. Learn more about measuring noise and about soundproofing from Soundproofist . Download the free NIOSH app from the App Store and learn more about it from this CDC documentation .
Participate in citizen science: learn how to map the quiet spaces where you live Dr. Antonella Radicchi is an architect, a researcher, and a soundscape urbanist. As part of her work, she developed an app called Hush City. You can get it from the App Store (for iOS) or from Google Play (for Android). When you're at a quiet place -- a street, a park, a beach, a path -- you can take note of it with the Hush City app. Make a recording, take a photo, and upload it to the Hush City map , and include your notes about your experience so you can share it with others. By mapping the quiet areas, you can also help urban planners to be aware of -- and protect -- these spaces. Listen to the conversation with Antonella Radicchi here.
