By operating an amplifying system, you can produce excessive sound pressure levels that may
lead to permanent hearing loss.
There are no serviceable parts inside the device. Maintenance and service operations are only to be carried
out by authorized dealers.
3 LEGAL INSTRUCTIONS
Operating an amplification system can produce extremely high noise levels that may cause a permanent
hearing loss. The legal instructions for using an amplification system vary from country to country. The user
must always inform himself on the legal instructions valid in his country and apply them to his situation.
Always monitor the sound pressure level when operating an amplification system in discotheques, concerts
etc. Never exceed the permissible noise level exposures as specified by your authorities. The monitoring of
the noise levels must be documented in an appropriate way.
In Germany, the following instructions are binding:
Strafgesetzbuch § 223 ff: bundesrecht.juris.de/bundesrecht/stgb
TA Lärm: www.umweltdaten.de
DIN 15905-5: www.din.de
Arbeitsstättenverordnung § 15: www.lgl.bayern.de/arbeitsschutz
Berufsgenossenschaftliche Vorschrift BGV B3: www.pr-o.info
VDI-Richtlinie: VDI 2058 Blatt 2: www.vdi.de
Hearing damage caused by high noise levels can be treated as physical injury and persecuted by law.
Please note that the organizer is responsible for keeping to a specified noise level. If this noise level will be
exceeded, the event may be cancelled immediately.
If the organizer does not fulfil his safety duties, he is reliable by civil law for any damages occurred, e.g.:
Pay the treatment costs of the damaged person.
Pay a smart money to the damaged person.
Economic damage caused can be demanded from the operator of the amplification system.
If hired persons work with amplification systems: the noise levels of music events are almost always too high.
This is why the entrepreneur has to set up warning signs and provide hearing protectors. The staff has to
use these.
Please note:
OMNITRONIC cannot be made liable for damages caused by incorrect installations and
excessive noise levels!
3.1 Information on hearing loss
More and more young people suffer from hearing loss of 25 decibel or more, mainly caused by loud music
from portable MP3 and CD players or discotheques.
Everybody operating amplification systems should know to what sound pressure levels he exposes his or the
audience's hearing. As an average levels between 75 and 105 dB(A) in the discotheque or 95 and 115 dB(A)
at a rock concert are reached. Individual peaks can exceed the pain level at 130 dB(A). Such levels are
typical for motor chainsaws or jack hammers.
