Acoustics Arup Acoustics “Melbourne’s Recital Hall will be ranked amongst the world’s great halls for its uncompromised acoustic, architecture and artistic program.” Excerpt from The Recital Hall Brief; December 2003 Arup Acoustics leads the international consortium providing acoustics, theatre planning and theatre technical systems advice for Melbourne Recital Centre. Lead Acoustic Engineer is Dr Raf Orlowski, based in ‘Arup Acoustics’ Cambridge UK. After a rigorous 2-year design phase, which included extensive consultation with Melbourne Recital Centre’s Industry Reference Group, construction of Elisabeth Murdoch Hall is under way. Acoustic design for Elisabeth Murdoch Hall Chamber music is the most intimate of musical performance genres. The role of the recital hall is to promote intimate communication between the players and to allow the audience to share the intensity and dynamics of the performance. The fusion of architectural and acoustic design throughout the development of Elisabeth Murdoch Hall has produced a visually and aurally exciting hall. Based on the proportions of the classic shoe-box shaped European concert hall, the geometry has been enhanced to provide greater acoustic intimacy and improved sightlines for the entire audience. The entire timber interior forms a unique instrument, purpose designed to complement and enhance chamber music performances. The interior surfaces incorporate an organic texture that diffuses the sound to enhance the timbre and blending of instruments. This form is further diffused by the pixelation effect of the upper surfaces and rear wall. The integrated design results in excellent strength and clarity with a rich, reverberant response that is unique to this hall. The mass of the timber lining has been designed to achieve strong bass response within the hall. This enhanced low frequency response provides a musically rich timbre to music presented in the hall, particularly for cello and bass. The most critical area in the design of a recital hall is the platform acoustics. The surfaces surrounding the platform must promote the delicate and immediate communication between ensemble players. Elisabeth Murdoch Hall has a unique, stepped ceiling surrounding the platform that has been carefully designed to provide strong acoustic reflections to support musicians hearing themselves, and to assist with ensemble with other players. The design of Elisabeth Murdoch Hall provides excellent acoustic strength and clarity with a rich, reverberant response. |
