ABSTRACT
This chapter explains the types of studio environment which has to be maintaining in the studio: lighting, ventilation and air-conditioning, foldback systems, studio decoration, AC mains supplies, and earthing. Traditionally, it has been the out-of-town studios which have been more inclined towards allowing daylight into the recording areas, probably because it was often easier to do this in the relative tranquillity of rural life, as opposed to the noisier inner-city locations. Electronic dimming systems using semiconductor switching can be a great noise-inducing nuisance, both via the mains power (AC) and by direct radiation. Since the beginning of the twenty-first century, the pressure on designers to try to use low-consumption lighting, where possible, has increased. In order to get the best out of a ventilation system there are a few points worth bearing in mind which are of great importance. One of the greatest rules is never to only extract air from the room.
