许多发烧友有这样的体会,同一套音响设备在试音间里的效果远远优于自己家中的效果。其实原因很简单:主要是家庭中的声学处理和音箱摆位两大因素制约所致。 现今的都市家庭,大多数居住面积在十几平米左右,且起居、娱乐等同处一室,若不对家中的声学环境和音箱摆位做适当调整,必然会直接影响音响的重放效果。 人们在试音间里听音乐时,人耳主要听到的是反射声。不同的物质对声音的反射效果是不一样的,吸音系数小的物质(如玻璃窗、水泥、地面、光滑的桌面等)对声音的反射较强。而吸音较强的物质(如绒布窗帘、沙发、床、被等)反射较弱。
Many fans have this experience, the same set of audio equipment in the audition room is far better than the effect of their home. In fact, the reason is very simple: the main family is the acoustic processing and speaker positioning caused by two major factors. Today’s urban families, most of the living area of about a dozen square meters, and living, entertainment and other facilities in a room, if not at home, the acoustic environment and the speaker to make the appropriate adjustments, will inevitably directly affect the sound playback. When people listen to music in the audition room, the main hearing of the human ear is reflected sound. Different substances have different effects on the sound reflection. Small sound-absorbing materials (such as windows, concrete, floor, smooth tabletop, etc.) reflect the sound more strongly. The sound-absorbing material (such as velvet curtains, sofas, beds, etc.) reflection is weak.
