The Sound Meter app measures and displays the decibel (dB) values of environmental noise. It presents this data through various visual formats like gauges, graphs, and numerical readouts, allowing users to understand the noise levels around them.
Key features include indicating decibel levels by a gauge, displaying the current noise reference, showing minimum, average, and maximum decibel values, presenting decibels via a graph line, and the ability to save measured records for later review.
Yes, the app is free to use. However, it does display advertisements as part of its monetization model. There are no in-app purchases mentioned.
The accuracy of the readings can be limited by the phone's microphone, which is primarily aligned to human voice. Very loud sounds (over approximately 110 dB) may not be recognized accurately on most devices. It is recommended to use this app as an auxiliary tool and consider an actual sound level meter for more precise measurements.
Common use cases include checking noise levels in different environments (e.g., home, office, public spaces), identifying potential noise pollution, monitoring sound for personal awareness, or as a supplementary tool for audio-related tasks.
