So, what can you do to protect your hearing if you're going to a loud concert like that? Definitely wear earplugs. You can even measure sound intensities if you want to be very quantitative about it, because now you have a rough formula. You can get a dB app on your phone. It's free. You can measure it. And let's say if it's 120 decibel at the concert you're using, then wear earplugs that provide at least 30 decibel of attenuation.
