EarDial

Know the sound level around you, and how long you can stay safely.

This app will tell you the approximate sound level pressure you are currently exposed to, and it will tell you how long you can stay at that level without risk of hearing loss.

You can find inside more information about the decibel scale, the noise dose formula, attenuation standards, and more.

This app was developed as a free companion for EarDial HiFi Earplugs - Invisible High Fidelity Hearing Protection, but it is useful even if you are not an owner of EarDial earplugs.

You can compare the results if you are wearing EarDial earplugs or not. When you activate the EarDial switch, it will adjust the calculations based on the EarDial attenuation levels.

You will be able to calibrate the app to your specific device if necessary. More information how to do that inside.
