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

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.
