Sennheiser 52 A Safety Manual page 5

Important safety instructions
The product can produce 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.
Inform all operators about these facts and, if necessary, ask them to set the volume
to a medium level.
