Live crowdsourced data

Know how loud it really is.

DecibelMap crowdsources ambient noise levels so you can check any neighborhood before you sign a lease, buy a home, or book a hotel.

Noise data that actually helps

Every listing says "quiet street." DecibelMap gives you the real numbers — crowdsourced from actual residents, broken down by time of day.

📊

Noise by Time of Day

See how noise levels change from 6 AM to midnight. Morning garbage trucks? Late-night bars? You'll know.

📍

Address-Level Data

Not just neighborhoods — get readings for specific blocks and intersections. Precision matters.

📱

Passive Contribution

Your phone's mic samples a few seconds, logs the dB level, then goes silent. No audio stored — ever.

🗺️

Heat Map View

Color-coded noise overlay. Green is peaceful, red is loud. Scan an entire city at a glance.

Three steps to quiet

1

Search any address

Type an address or drop a pin. See all available noise readings, color-coded by intensity.

2

Check noise by time

Filter by morning, afternoon, evening, or late night. The profile at 8 AM vs 11 PM can be completely different.

3

Contribute readings

Hit record for 6 seconds. Only the decibel number is logged — no audio is ever stored or transmitted.

Built for real decisions

🏠 Home Buyers & Renters

That "charming" Airbnb might sit above a nightclub. Check the noise profile before you book.
