Sound Insulation Structure in Auditorium Buildings-part 2 An example of the measurement results of sound insulation in a rock music performance space

摘要

As far as rock music concert concerned, the sound pressure levels in auditoriums are getting larger and larger by the increasing number of the loudspeaker settings and diversification of the music. The frequency characteristics of rock music concert tend to have the special characteristics that the low-frequency ranges are very large. Therefore, the study of the sound insulation has been very important task for the rock music concert spaces in the city area. However, there are not many reports of the measurement examples of sound pressure level differences in the rock music performance spaces. This report shows the noise control design and the measurement results of sound insulation in a rock music performance space which is newly-built auditorium installed with floating-sound-isolation structure.
