不少朋友购买的“家庭影院”设备,往往各个组件都很不错,系统搭配也没有毛病,但是搬回家后效果却不理想。其实,在许多情况下,并不是设备性能的问题,而是由于房间的大小、形状、结构、材料以及室内物品的摆设、布置不合适造成的。 音响发出的声波在室内以直射、反射、绕射的形式传播,并受到媒质、环境、路径的影响。人耳接收的声音,主要是直达声和被地面、天花板、墙壁、家具等物品反射过来的混合反射声。声波在室内各个方向来回反射,使进入耳中的声音增大,而又逐渐衰减的现象,这就是“混响”。混响对音质有较大的影 Many of the “home theater” equipment purchased by many friends often have very good components, and there are no problems with the system, but the effect of moving home is not satisfactory. In fact, in many cases, it is not the performance of the equipment. It is caused by the size, shape, structure, material of the room, and the improper placement and arrangement of the interior items. The sound waves emitted by the sound are transmitted in the form of direct reflection, diffraction, and are affected by media, environment, and paths. The sound received by the human ear is mainly direct sound and mixed reflections reflected by objects such as floors, ceilings, walls, and furniture. Sound waves are reflected back and forth in all directions in the room, causing the sound in the ear to increase, and gradually decay again. This is “reverberation.” Reverberation has a greater impact on sound quality
