This system is capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the sound pressure cor- responding to the maximum permissible volume which is by law (in some countries) allowed to affect your hearing for the duration of a working day. It is used as a basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be short- ened in order to prevent hearing damage. The following are sure signs that you have been subjected to excessive noise for too long a time:
yYou can hear ringing or whistling sounds in your ears.
yYou have the impression (even for a short time only) that you can no longer hear high notes.
