Musicians have two requirements for their hearing.
They need a high quality hearing and at the same time are in the danger of damaging their hearing.
Even during an opera up to 80dB constant noise level and 120dB peak level can be measured. Protect your hearing with unique hearing protection earplugs especially for musicians. Even for hobby musicians or concert visitors it is important to protect your hearing.
See it as a warning sign when your ears ring after leaving a club and that ringing endures till the next morning. Even if not experienced as loud music, it still destroys your hearing irretrievable.
