Sound Meter: Noise Detector

Want to know how loud your surroundings are? Sound Meter: Noise Detector turns your phone into an easy-to-use sound level meter for checking environmental noise in real time. Use your phone's microphone to estimate surrounding sound levels in decibels (dB), follow changing noise on a live graph, view Min/Avg/Max readings, and set a noise level that can trigger alerts when sound becomes louder than your selected threshold. REAL-TIME SOUND METER See the current sound level instantly with a clear dB gauge. The app continuously measures surrounding sound while monitoring is active and gives you an easy-to-understand indication of the current noise environment. From a quiet room to busy traffic or loud music, quickly get an idea of how the sound around you changes. MIN, AVERAGE & MAX dB A single number doesn't always tell the whole story. While measuring, Sound Meter tracks your current session and displays your: Minimum dB Average dB Maximum dB Reset the statistics whenever you want to start a fresh measurement. LIVE NOISE GRAPHS Watch sound levels change visually as they happen. Switch between graph views to see short-term changes or follow a wider view of your current sound measurement. Sudden increases and quieter moments are easy to spot. CHOOSE YOUR NOISE LEVEL Select a noise threshold based on common sound-level references. Available reference levels range from quieter environments such as whispers and libraries to traffic, factories, loud music and other high-noise environments. Your selected level is also displayed on the live graph, making it easy to compare the current reading with your chosen threshold. LOUD-NOISE ALERTS Want to know when sound rises above your selected level? When active noise measurement exceeds your chosen threshold, the app can alert you using: Sound alert Vibration alert Flashlight alert on supported devices Choose which alert methods you want from Settings. EASY MEASUREMENT CONTROLS Start or pause sound monitoring with one tap. Reset Min/Avg/Max statistics whenever needed and switch graph views directly from the measurement screen. The simple interface keeps the information you need easy to read. COMMON NOISE REFERENCES Compare dB levels with familiar examples such as: Quiet whisper Quiet library Conversation Busy traffic Busy street Factory noise Subway train Rock music Thunder These references help make decibel readings easier to understand. USE SOUND METER FOR EVERYDAY NOISE AWARENESS Sound Meter: Noise Detector can be useful for checking surrounding sound at home, at work, while studying, around appliances, near traffic, during events, or anywhere you want a quick estimate of environmental noise. It combines a sound meter, decibel meter, dB meter and noise detector in one simple utility. IMPORTANT MEASUREMENT NOTE Sound readings depend on the microphone hardware and audio processing of your Android device. Different phones may produce different measurements, and built-in microphones have limitations when measuring very quiet or very loud environments. Sound Meter: Noise Detector is designed as a convenient environmental sound reference and should not be used as a replacement for certified professional sound-level equipment in occupational, legal, medical, scientific or safety-critical situations.

What's new: • Frequency Analyzer: see a live sound spectrum, find the dominant pitch, and check how much of the noise is low, mid or high frequency • Full-screen display on newer Android phones • Faster performance and lower memory use • Bug fixes and stability improvements
