Standing too close to the speakers at just one music concert is enough to permanently damage your ears. Our hearing is highly sensitive and should be taken good care of.

The degree of sensitivity varies from person to person and can’t be determined in advance.

Earplugs
 
So be sure to make use of hearing protection. At AB you can purchase ear plugs through special dispensers. They cost 2 tokens and can be reused 5-6 times. You will find the dispensers near the main bar, in AB Club and in the bar space to the left of the main stage (Foyer).
