Research about acoustics in heritage. In many of the redeveloped buildings, the acoustic quality is very poor. The reverberant times are very high due to the little amount of absorbing surfaces and some frequencies gain a higher G-strength then other frequencies. This is for a part due to the dimensions of the spaces. For example; churches with concave surfaces and very high ceilings. The other part is caused by the materialisation of the buildings. The materials are mainly chosen because of their constructive or aesthetic properties. The masonry and concrete hardly absorb any frequencies, which causes a high reverberation times, and wooden floors basically absorb a little bit of the low tones (due to the resonance frequency). However, some buildings could be very suitable for theatres and arts centres because of their central location in cities, but due to the poor acoustic quality this is a big design challenge. In the design question, two important demands conflict with each other; Both the cultural value of the existing building and the acoustic quality demands large surfaces. Cultural value needs to be seen by the users, but sound needs to be absorbed and reflected in a complex way. How can heritage be a place for music?
