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 organiser 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!
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 cassette recorders 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.
Overview on the different noise levels
10 dB Heartbeat
20 - 30 dB Whisper
40 dB Average home
50 dB Light traffic
60 dB Normal conversation
70 dB Vacuum cleaner
80 dB Heavy traffic or telephone ringing
90 dB Pneumatic drill
100 dB Power mower
120 dB Boom box in car
130 dB Pain level
140 dB Jet plane 30 meters overhead
It is important to know that doubling the power increases the noise level by 3 dB. The human hearing does
only recognize a doubling of the sound level when the noise level is increased by 10 dB. Damaging the
hearing does not depend on the sound level but on the noise level and starts way before the pain level.
Many people deceive themselves by thinking that noise is something they can get accustomed to. It is
possible that a positive opinion of a certain noise can reduce the physiological reaction, but the slow impacts
on the inner hearing must not be neglected: over stimulation and continuous elimination of the Coptic organ's
hair cells.
The reason why some people have got accustomed to a certain noise level and are no longer disturbed is
that they have already suffered a hearing damage. This damage make the insensitive to those frequencies
forming the loudest part of the noise. Getting accustomed to noise does not mean anything other than trying
to get along with the hearing loss in everyday life. The hearing loss itself cannot be healed, it can only be
compensated by hearing aids.
