Acoustical engineering is an especially tricky business. Just ask anyone who has been in charge of designing the sound of a major concert hall over the last half-century. “Over the last 50 years, more computing power has been applied to acoustic data than ever before, but most big halls have turned out to be dry and pale frames for music.” In fact, as acoustic science has advanced, concert halls have arguably regressed, sounding more like glorified loudspeakers or hi-fi sets than chambers of orchestral sound. Perhaps the problem is the desire to build a hall that can be all things to all people, or the corruption of our ears and minds by recorded sound. But whatever the problem, one thing seems clear: they just don’t build ’em like they used to.
