Danger of hearing damage due to high volumes
This is a professional receiver. Commercial use is subject to the rules and
regulations of the trade association responsible. Sennheiser, as the
manufacturer, is therefore obliged to expressly point out possible health
risks arising from use.
This receiver is capable of producing sound pressure exceeding 85 dB(A).
85 dB(A) is the sound pressure corresponding 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 shortened in order to prevent hearing damage. The
following are sure signs that you have been subjected to excessive noise
for too long a time:
You can hear ringing or whistling sounds in your ears.
You have the impression (even for a short time only) that you can no
longer hear high notes.
