Congratulations on building a nice-looking app that addresses a legitimate need.

I'd like to see some proof that this is able to accurately measure noise level across a range of devices. The CDC have a sound meter app [1] which has been tested to 2db accuracy, and they only make that available on specific Apple devices because calculating noise level depends on the hardware.

I'm sorry to ask, but I'm seeing many cases of AI apps making accuracy claims based on the author’s ‘reasonableness spot checks’ but with no statistical testing that the outputs are accurate.

In my own reasonableness spot check, what measures as 37dB on my phone is showing as 49dB on my laptop

A calibration function has been added; hopefully this will help.

Thank you for your feedback. I will adjust the accuracy settings immediately.
