良好的音响设备还必须与合格的听音室相结合才能够造就出理想的效果,这一点往往被爱好者所忽视。不注意音响室的技术条件,一味追求贵重设备是偏面的。换句话说,若在听音室上下了工夫,廉价的装置也会造就出优良的效果。设计听音室时要考虑下列因素。 (1)隔音:这是为了防止外来噪声干扰立体声的重放及隔离重放声音的外泄。一般音响室内噪声大小都规定在30phon以下,要求低可定为45phon以下。 (2)吸音特性适中:房间吸音特性影响室内声音传
Good sound equipment must also be combined with a qualified listening room to produce the desired result, which is often overlooked by hobbyists. Do not pay attention to the technical conditions of the acoustic room, blindly pursue expensive equipment is partial. In other words, cheap devices can produce excellent results if you work in the listening room. Consider the following factors when designing your listening room. (1) Sound insulation: This is to prevent external noise from interfering with the reproduction of the stereo sound and the isolation of the reproduced sound. General audio room noise levels are provided below 30phon, low requirements can be set at 45phon the following. (2) Moderate sound absorption: the sound absorption characteristics of the room affect the indoor sound transmission
