一个房间的听音效果取决于房间的三个声学特性,即反射性、吸收性和漫射性。房间的大小、形状及音箱的放置位置与房间四壁的相对位置都影响上述特性。一般来说,听音室需要一定的反射性(混响),且反射最好不要发生在接近音箱的区域;还需要一定的吸收性和漫射性。反射过弱或吸收过强会使声音听起来很“干”或是很“死”,这样的房间也许会提高立体声声像定位的准确度,但代价是失去了声音的生动性,反射过强则会使声音模糊不清且常常加重高频使声音听起来很是刺耳。漫射声能令音质自然、悦耳。对于有足够的反射性、声音较生动的房间来说,在调整过程中,提高其漫射性要比增加吸音性效果来得更好。 在理想情况下,用作听音室的房间各个墙面应不相平行。
The listening effect of a room depends on the three acoustical properties of the room, ie reflectivity, absorption and diffusivity. The size and shape of the room, the placement of the speakers and the relative position of the four walls of the room affect the above characteristics. In general, the listening room requires some reflectivity (reverberation) and the reflections should preferably not occur in areas close to the loudspeaker; it also requires some absorption and diffusivity. Too weak a reflection or too much absorption can make the sound sound “dry” or “dead”, and such a room may improve the accuracy of the stereo sound image localization, at the cost of losing the vividness of the sound and strong reflection It will make the sound obscure and often increase the high frequency so that the sound sounds very jarring. Diffuse sound can make the sound quality, sweet. For more reflective, more lively sound room, in the adjustment process, to improve its diffuse than to increase the sound-absorbing effect to better. Ideally, the walls of a room used as a listening room should not be parallel.
