Free SPL Meter App - From a US Government Agency

From the Centers for Disease Control and Prevention, National Institute of Occupational Safety and Health.

https://www.cdc.gov/niosh/topics/noise/app.html

This free app, used to measure sound pressure levels, AKA loudness, can also tell you when you have received a "dose" of sounds that could be harmful.

Happy listening!
