Awareness Thus, without too much guilt, the client constructs a building as cheaply as possible and, if it is noisy, blames the tenant for a fit-out which didn’t cater for noise control. Quantity surveyors (the QS) are supposed to do cost estimating, cost control and so on in building projects. They very often omit any allowance for acoustics and noise control or the services of a consulting acoustics engineer. They defend this stance by saying “the client doesn’t want it”. This is true, but often it is the QS who is keen to keep costs down, just because. I was at a meeting last year concerning the acoustics and noise control in a hospital. The QS told us that noise control was not necessary in the hospital since “none of the other hospitals they had worked on had any specific noise control”. The hospital was built. A trolley pushed down a corridor can be heard in every part of every ward. Very restful. Interior designers don’t help. Apart from a fee, they get a royalty on every item of interior design that they specify. This leads to a very incestuous relationship with suppliers of door, tiles, wall hangings, ceilings and glass suppliers. Thus, if there is a consulting acoustic engineer on the project, any design suggestions which involve surfaces which have some acoustic Acoustics and noise control function, are kicked out by the interior designer who has a vested interest it their proposed design. “The client has seen this” they say “and he likes it”. Finished. But it is not all doom and gloom. There are architects out there who really care. Cape Town International Airport (Blue Print Architects) is one of the quietest in the world – a complete absence of “airport rumble”. The UWC learning centre (DHK) is a masterpiece, both visually and acoustically. Curro School Chamber Music Hall (James Basson, Curro) is so good, acoustically, that the University of South Africa music exams were held there. Bloemhof Electricity building (EBSA) has an auditorium which is close to perfect. Khayelitsha Library (Chamberlain and Irving) is all, acoustically, that a library can be. Other structures: SSOB building (ACG Architects), MyCiti Cape Town terminal (ARG Architects) and others are also good. But Cape Town Stadium (acoustically rubbish), Bellville Velodrome and many others, are terrible. Things need not change – South Africans frequently put up with what they get in terns of acoustics and noise control. They shouldn’t have to. But until project execution and attitudes transform, nothing, acoustically, will change. 23
