Great app

Just got this app, I’m shocked at how much background noise there is in my ‘quiet room’. Revealing a constant humming sound, I thought it was a problem with my ears, it’s not it’s really there.

Likely AI Slop

I tested this application in a quiet room and it reported an unrealistic 45 dBA for the noise level, and worse, the displayed average was not even calculated correctly.

Not accurate

Even in a quiet room, it indicates ~55-60dB of "Speech/Noise" while other app (which I think is more accurate) only about 40dB. Even when saving records is free, the app is not practical

FAQ

What does the Sound Meter app do?

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.

What are the key features of this sound meter app?

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.

Is this app free to use?

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.

How accurate are the decibel readings?

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.

What are common use cases for a sound meter app?

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.
