Three things, and each takes under a minute: measure the place you're in, find places you can talk in, and speak up about the ones that are too loud.
Questions? The FAQ covers phones, accuracy and SoundCheck Points.
Open the app and tap SoundCheck. The phone's calibrated decibel meter listens for fifteen seconds — longer is better — then you pick the place from the list of what's around you and submit. Your measurement joins the database for everyone.
Tip: take the SoundCheck first, then pick the venue. Keep Wi-Fi switched on (it doesn't need to be connected) so the app knows exactly where you are.
Search any city. Every measured place shows its sound level and distance, on a list or a map. The filter narrows to Quiet or Moderate places only, or widens the distance if you're outside a city center.
Tip: grey pins are places nobody has measured yet. Be the first.
When a place measures Quiet or Moderate, the last step of the submission lets you nominate it for the Quiet List — a way to promote and reward a venue that gets it right. When it measures Loud or Very Loud, the same spot lets you make a noise complaint, counted per venue and shown to everyone, to put the venue on notice. Use either only when it's warranted; most SoundChecks need neither. That's what keeps both signals strong.
