To go out well prepared you need the Alpine MusicSafeCheck-app. You can measure the sound level in for instance a nightclub. The app will instantly inform you how long you can remain in an area with or without earplugs.
Tip: do not forget to rotate your iPhone/iPad because the microphone is at the bottom!
