Sound Meter

Sound Meter is a professional noise measurement tool that turns your Android device into a decibel meter. Measure ambient sound levels in real time, visualize noise data with dynamic charts, and track your measurement history. Whether you are checking noise levels at home, in the office, or outdoors, Sound Meter provides the data you need to understand your acoustic environment.

Key Features:

Real-Time Decibel Measurement
Measure sound levels in your environment with real-time decibel readings. The app captures audio through your device's microphone and converts it to accurate dB values that update continuously. Watch the noise level change in real time as sounds around you fluctuate.

Decibel Gauge Visualization
A large, intuitive gauge display shows the current sound level with a smooth, animated needle. The gauge provides an instant visual reference that makes it easy to read noise levels at a glance, even from a distance. Color-coded zones help you quickly identify quiet, moderate, loud, and potentially dangerous noise levels.

Comprehensive Statistics Display
View current, minimum, maximum, and average sound levels simultaneously with dedicated statistics cards. These metrics give you a complete picture of the noise environment over your measurement session, useful for identifying both peak noise events and sustained noise levels.

Recording Session Tracking
Start and stop measurement sessions to capture noise data over specific time periods. Each recording session tracks its duration and all measured values, creating a comprehensive record of the acoustic conditions during that period.

Historical Data Charts
Review your sound measurements over time with detailed trend charts. The decibel history chart plots your readings as a continuous line graph, making it easy to spot patterns, identify when loud events occurred, and understand how noise levels change throughout your measurement period.

Waveform Visualization
See sound waves represented visually with the real-time waveform display. The waveform chart adds another dimension to your noise monitoring, showing the shape and pattern of audio signals in addition to their volume levels.

Noise Level Categorization
The app automatically categorizes the current noise level into intuitive zones such as quiet, normal, loud, and danger. Each category is clearly labeled and color-coded, helping you instantly understand whether the ambient noise is at a comfortable level or potentially harmful to hearing.

Session History and Archive
Save your measurement sessions for future reference. Browse through your archived sessions to compare noise levels across different locations, times, or conditions. The history feature is valuable for documenting noise conditions in workplaces, neighborhoods, or any environment you want to monitor.

Measurement Metrics Dashboard
The statistics cards display key metrics in a clean, organized layout. View peak levels, average exposure, and measurement duration all in one place, providing the summary data needed for noise assessment and reporting.

Professional Accuracy
Sound Meter uses advanced audio processing to deliver reliable decibel readings from your device's microphone. While results depend on your device's hardware capabilities, the app is calibrated to provide consistent and useful measurements across a wide range of Android devices.

Multi-Language and Theme Support
Use Sound Meter in your preferred language with support for English, Chinese, Japanese, Russian, and Portuguese. Choose between light and dark themes for comfortable viewing in any environment.
