摘要

A recital hall of light weight construction had been commissioned. The newly built hall was reported to be loud with an unusual balance by professional musicians. Hence, the Acoustics Group was asked to independently assess the room acoustics of the hall. The hall had a volume of approximately 800m~3 with flexible seating for up to 100 people. The hall had a beautiful traditional wood finish and a floor comprising a single continuous area with no raised elements. To give a flexible acoustic curtain rails run down either side of the hall, see Figure 1. The curtain rail then runs behind a fake rear wall which hides the curtain when not in use, see Figure 2. The hall is now always configured with the curtains fully extended, as this is the subjectively preferred condition by the performers. This paper reports on the effect on the acoustics of the hall of the fake rear wall and the curtains through sets of room acoustic measurements.
