Sound meter : SPL & dB meter

The Sound Meter app serves as a practical tool for measuring environmental noise, elegantly transforming your smartphone or tablet into a sound pressure level meter (SPL), commonly known as a noise level or decibel (dB) meter. Utilizing your device's microphone, it offers a swift and effortless method to conduct sound tests or noise assessments, presenting results in decibels. It should be noted that the readings may not be as exact as those from a dedicated SPL meter due to the typical calibration of device microphones for human voices.

To enhance accuracy, users should calibrate the app using an actual sound level meter, or adjust the settings in a very silent environment, aiming for a baseline reading between 20 to 30 dB, if a professional meter is unavailable.

Key features include:

- Real-time noise and sound measurement displayed on a chart graph.

- Recording of minimum (Min), maximum (Max), and average (Avg) decibel levels during a session.

- Monitoring of total measurement time.

- Available Reset button for starting fresh measurements.

- Play and Pause buttons for control over the recording session.

This tool illuminates the wide spectrum of noise levels, from the rustling of leaves at a serene 20 dB to the potentially harmful 140 dB produced by gunshots. Continuous exposure to high decibel ranges can adversely affect both physical and mental well-being. By assessing environmental noise, the app provides users with valuable insights to make informed decisions about their auditory surroundings and helps in protecting their health.
