Abstract:
Sound reinforcement systems in music clubs have become the synonym for sound
sources that produce excessive noise levels, both in indoor and outdoor
facilities. Typical sound insulation measures, such as the box-in-a-box
design, cannot be applied for music clubs located outdoors. The only means of
sound level control are the frequency equalization of loudspeakers, their
proper positioning in space and the overall sound level limitation. Noise
barriers can be placed as well, but their efficiency is usually very limited
due to the high positioning of loudspeakers. In this paper, the problem of
excessive noise levels in the famous bay of Zrce in Croatia will be presented,
where five large music clubs attract several thousand visitors each day during
summer season. Many complaints have been made by residents of nearby towns and
villages over the last couple of years. Noise levels of more than 70 dBA were
measured in those settlements during the day, but also in night time.
Simulations of sound propagation from the sound reinforcement systems to the
nearest settlements will be presented, along with measured noise levels. The
proposed and implemented solution for successful coexistence of music clubs
and settlements will be discussed.
