Monitor, Measure, and Understand Noise with Noise Detector – Decibel Meter

Noise Detector – Decibel Meter is a precise and easy-to-use sound level monitoring app designed to help you stay aware of your environment. Whether you're at home, in the workplace, outdoors, or in public spaces, this tool provides accurate real-time sound measurements using your device's microphone. Gain valuable insights into the noise around you and take steps to improve your comfort, focus, or hearing safety.

🔊 Real-Time Noise Monitoring

Stay informed about the sound levels in your environment with a live decibel (dB) meter. The app continuously captures audio input and displays current sound intensity in real time. Whether you're testing equipment or simply checking your surroundings, you’ll always have an up-to-date noise reading at your fingertips.

📏 Track Min, Max, and Average Decibel Values

Every measurement session displays three key statistics: minimum, maximum, and average sound levels. These metrics help you better understand sound behavior over time, identify consistent noise sources, or recognize when sudden spikes occur in your environment.

📉 Visual Sound Graph for Better Insight

The dynamic graph gives you a clear visual representation of decibel fluctuations. It’s ideal for identifying trends in sound levels during meetings, classroom activities, home recordings, or outdoor monitoring. Watch changes unfold as the graph updates in real time during each session.

📚 Reference Guide to Noise Levels

Not sure what the numbers mean? The built-in noise reference chart helps you compare your readings to common sound sources. From quiet whispers to busy streets or construction zones, this guide offers useful context for interpreting decibel levels and understanding what’s considered safe or potentially harmful.

🔧 Device Calibration for Accurate Readings

Different devices have different microphone sensitivities. That’s why this app includes a calibration feature to help fine-tune measurements for your specific phone or tablet. Adjusting the input level improves overall accuracy and ensures more reliable results in different environments.

🕒 Automatic History & Session Logs

Keep track of all your sound monitoring sessions with the built-in history feature. Previous readings are saved automatically, making it easy to compare data across different times or locations. This is especially useful for long-term tracking, environmental studies, or sound policy assessments.

🚨 Customizable High dB Alerts

Protect your hearing or reduce distractions by setting up a decibel warning threshold. When the surrounding noise exceeds your selected limit, you’ll receive an alert. This is helpful in settings where sudden loud sounds could cause discomfort, health concerns, or disruption.

🎨 Light and Dark Theme Options

The user interface offers both light and dark modes for visual comfort. Easily switch themes based on your preferences or lighting conditions, whether you’re using the app during the day or in low-light environments.

🖥️ Convenient Mode for Large Display

Need better visibility during hands-free operation? Turn on Convenient Mode to enlarge the main sound display for easier readability. Perfect for use during presentations, fieldwork, or when the device is placed on a desk or stand.
