Sound Meter & Frequency Meter 5.2

The Sound and Frequency Meter, commonly referred to as a sound level meter, decibel meter, or noise meter, is an application designed for accurate noise level and frequency measurement. Utilizing the phone's microphone, it effectively gauges sound pressure levels in decibels (dB) and frequency in hertz (Hz).

Key features of the Sound and Frequency Meter include:

• Graphic display of current volume and frequency values
• Display of current, average, and maximum decibel levels
• Measurement of elapsed time
• Decibel range from 0 to 120 dB
• Frequency range from 0 to 18,000 Hz
• Quick reaction time
• Options to reset, play, or pause measurements
• Simple calibration process
• Display remains active while the application is running

The application leverages the built-in microphones of Android devices, which are typically optimized for capturing human voice. As such, it may struggle with very high noise levels, often failing to register sounds above 100 dB. The sound meter is calibrated within a ±2 dB range of ambient noise, positioning it among the more accurate sound measurement tools available on Google Play. The development process involved incorporating professional-grade sound engineering equipment and adapting it for compatibility with a wide array of Android devices.

The practical applications of the Sound and Frequency Meter are extensive. It can be used to assess noise levels from neighbors, appliances such as refrigerators and air conditioners, or vehicles like cars and motorcycles. Additionally, users can ensure that their audio systems are set at safe volume levels to prevent hearing damage. This functionality can also benefit prospective home buyers by measuring ambient noise in potential living spaces.

It is important to note that due to variations in microphone quality across different devices, measurement ranges may differ. Typically, low-end measurements are influenced by inherent microphone noise, while upper-end limits are constrained by microphone distortion.
