Sound and Noise Detector

What is Sound and Noise Detector?

View estimated sound levels on your Android phone and follow how they change around you. This decibel meter shows a live dB reading, lets you save sound-level logs and offers alarm limits for your own informal monitoring.

Use the readings to explore everyday sound, not to certify that an environment is safe or meets a noise regulation.

Who is Sound and Noise Detector for?

Use it when you are curious about the sound around you at home, at school or in another everyday setting. Watch a reading as the surroundings change, save a result to look back at later, or share it with someone else.

It also suits informal demonstrations of changing sound levels. The app is not a replacement for a calibrated professional meter or an occupational noise assessment.

What does Sound and Noise Detector do?

🎧 Follow live decibel readings
See the current estimated sound level in dB and observe changes while monitoring. See sound descriptions alongside the readings without treating a label as proof of the exact noise source.

🔔 Set your own alarm limit
Choose a sound-level limit and receive an alert when the monitored level exceeds it. The limit is your monitoring preference, not a certified safe-exposure threshold.

📋 Save and review logs
Keep sound-level results with their dates and times. Review your saved readings, filter the log by date or level, and return to earlier observations without relying on memory.

📤 Share a result
Use the sharing option to send a sound-level result through an available app on your phone.

📱 Check sound levels offline
View sound readings without an internet connection. Sending a shared result through an online service may still require connectivity.

How does Sound and Noise Detector work?

Open the app where you want to observe the surrounding sound. Watch the live dB display, and use the log option when you want to keep a result. Open your sound-level logs to review or filter earlier entries.

Set an alarm limit if you want a notification when the monitored level rises above your chosen threshold. Use the share option when you want to send a result to someone else.

Compatibility and requirements

This is an Android sound-level app for general information. Phone readings are estimates and can vary with the device and conditions. Do not use them to certify regulatory compliance, assess occupational exposure or decide that sound is safe for your hearing.

The app contains ads and offers in-app purchases.

Sound and Noise Detector brings live readings, logs and sharing together so you can explore changes in everyday sound.
