Sound and laser
What does the sound and laser ordinance regulate?
High sound levels pose a non-negligible risk of incurable hearing damage. Visitors to concerts, discos, or other events can be endangered by high sound levels, regardless of the source and whether they are perceived as pleasant or unpleasant.
Lasers have certainly been used at various events for more than ten years. Increasingly effective effects are presented at such laser shows, involving ever more powerful laser beams and more elaborate control systems. Laser beams are often directed into the audience. However, if a laser beam hits the eye, irreparable damage to the retina, which means impaired vision or even blindness, can be the result.
The purpose of the Sound and Laser Ordinance (SLV) is to protect visitors from these dangers.
No hourly levels above 100 dB(A)
No hourly levels above 100 dB(A)
The Sound and Laser Ordinance (SLV) regulates the sound level limits at outdoor and indoor events (open airs, discos, concert halls, cinemas, etc.), where electroacoustically generated or amplified sound affects visitors. In this context, events aimed exclusively at youths under 16 may not be louder than 93 dB (A). For all other events with a sound level above 93 dB (A), additional measures must be taken to protect the public and be reported in advance to the Office for the Environment.
Laser yes, but safe!
There are three categories of events that require varying degrees of protection:
- Category I: Events with a sound level up to 96dB (A)
- Category II: Events with a sound level between 96dB (A) and 100dB (A) and a maximum duration of three hours
- Category III: Events with a sound level between 96 dB (A) and 100 dB (A) and a duration of more than three hours
Laser yes, but safe!
The Sound and Laser Ordinance is intended to ensure that the risk of accidents is minimized at events with laser shows. This is brought about by self-responsibility of the organizers, by avoiding laser radiation in the audience area, by following technical guidelines, by expertise, care in planning and installation and operation. Any potential danger to the public must be prevented. All events with lasers must be reported in advance to the Office for the Environment .
