一、房间设施的摆放方式由于视听室对于长宽高比例都有一定的要求，本现场很难实现完美的黄金分割。但是沙发贴墙摆放会导致环绕效果的丧失，导致视听音质的下降。房间整体的布置方式，可以考虑进行 90°旋转，及沙发位于门的前方，“中置”偏后的位置。二、混响时间控制的实现家庭视听室在 500HZ的最佳混响时间为 0.4~0.6s，根据赛宾公式可以计算出房间的总的吸声系数。根据现场情况可以参考如下设置：1。墙面吸音的设置。前墙及侧墙采用深*质吸音板(做法见隔声部分的说明)，可以保证足够的吸声。颜色采用深色，是为了更好的还原视觉效果。2.为了避免驻波的出现，在前墙墙角设置低频陷阱(为 1/4圆柱形吸声体)。同时，在顶面第一反射区设置扩散吸声结合结构(可以采用“十字栅格+吸声体“的方式 );侧墙设置扩散体(可以用连续的半圆或者三角柱体形态，面层为吸声材料)。3.地面为了避免过强的声反射，采用软木地板，在沙发区可以放置一定厚度的地毯。三、室内家具陈设在视听室内，应的布置一些吸声材料，如壁挂毛毯，地面地毯，软包，松软的木材等，避免大面积的玻璃、石材等镜面材料出现。在侧墙摆放碟架等装饰架，能够实现扩散体的作用。沙发的选择靠背也不一定要太高，一般要低于视听室内人正常的听音高度。四、音响设备的布置需要咨询专门的供应商。当然，如果对于视听条件要求不是很苛刻的话，可以选择第二点的 c和第三点作为装饰中的参考点。另外，软包之类的吸声材料是没必要满铺的，吸声过强、混响不够会导致声音过于干*;墙面还应适当的布置扩散体，主要控制的区域为第一反射和两个侧墙。决定视听室的视听效果的因素，设备与室内空间设计比重几乎是等同的，这点是值得引起注意的。希望我的回答能帮到你。

1、了解建设方（业主）对设计的要求。 2、根据设计任务收集设计基础*，包括项目所处的环境、自然条件、场地关系、土建施工图纸及土建施工情况等必要的*。 3、熟悉设计有关的规范和定额标准，了解当地材料的行情、质量及价格，收集必要的*，勘察现场，参观同类实例。在对建设方意向及设计基础*作了全面了解、分析之后确定设计计划。在签订合同或制定投标文件时，还包括设计进度安排和设计费率标准。方案设计阶段方案设计阶段主要内容包括方案构思、方案深化、绘制图纸、方案比较四个阶段。

一、房间的长、宽、高应有良好的比例大多数的情况下,房间都是已建筑好了的.长度、宽度和高度的比例也早已定好.但如果有机会选一间房间来作听音室时,应尽可能地避免产生驻波.因为这也是让音响器材能够获得良好的声重放效果的一个先决条件.二、摆放好音箱音箱的正确摆放是在室内获得良好声重放效果的关键.如果愿意花上几个小时的时间,一边试听一边为音箱找到此恰当的摆放位置,就不但能够获得良好的声重放效果,而且还增加了聆听的经验并能够听出音质上的差别.所有的室内声学处理皆是以音箱的恰当摆放为基础的.音箱的摆放如果不对,其余的一切努力都是徒劳的.三、吸收或散射侧墙和地面的反射要设法在聆听位置跟音箱之前的光滑地面上铺设一块地毯,在音箱跟聆听位置之间的侧墙上贴些吸声或散射声波的材料,尽量避免在音箱的近旁有光**的墙壁和窗户之类反射表面.摆放在侧墙一边的书架也能很好地扩散声波.四、争取有间高度甚高并带有斜坡的房间虽然未必一定能办得到,但如果真的能够选一间高度较高并带些坡度的房间来作听音室便是最好不过了.这样的房间不仅可以改变地板与天花板之间的室内共振模式,还能够减少聆听位置上的早期反射,使低音更浑厚圆润,空间感更宽敞.音箱则应摆放在天花板低些的一端.五、移动聆听位置,让低音达到最佳平衡驻波将在室内产生一些恒定不变的高声压和低声压区.可以试试移动聆听位置,以便达到最佳平衡效果.避免坐在靠近后墙的地方,因为这里的低音会相对过重.六、让高音和低音的吸收达到平衡大多数的房间往往会对高音的吸收过多,而对低音的吸收则不够.需要用地毯、窗帘以及柔软的家具之类跟一些吸收低音的材料配套使用,以便使混响时间在整个频带内可以保持不变.过重而缓慢的低音便是由混响的不均衡所引起的
