关于喜欢直达声,还是带反射声的混响稳态声,也别太着急下结论?
否则也就不会有那么多360度辐射的hi-end音响了吧。
房间小的话,直达声也就将就了,都混起来,还不够乱的了。房间够大的话,还是再考虑考虑吧。
Floyd Toole博士好像是也倾向于后者的。Reflections within listening rooms are real and numerous. Some would argue that they all are problems to be eliminated. Others take a more philosophical view that they just provide information about the room, and the brain can figure it out. I’m somewhere in the middle, but leaning towards the latter. The science that has been done so far seems to be on my side.

刚刚才了解到,这位Linkwitz可是大人物呀,现在的分频器原理,好像就是基于他的1976年发明了。

SL: True, and it depends upon how much later the reflections arrive at the listener's ears than the direct sound. If within less than 3 ms, then they fuse with the direct sound. But if more than 6 ms, then the brain can differentiate them from the direct sound and associate them with the sound of a room corner.
SL: It would be a reverberation chamber. But nor is an acoustically dead room, like an anechoic chamber, desirable. Hearing has evolved in support of survival. We have the ability to find the direction to a source of sound by moving our head and using the time and intensity differences between the ear signals. We can also segregate streams of sound and focus attention on what is of interest. Those abilities come into play when you listen to loudspeakers in a room. And of course, if the room is too live, then stereo imaging suffers. If the room is too dead then it becomes uncomfortable for socializing, but it is deemed to be a good work environment*** for a mixing/mastering engineer. Listening for pleasure requires a room with some liveliness. It requires reflections with a 60 dB reverberation time in the order of 400 ms to 600 ms. It is of utmost importance that the loudspeakers illuminate the room neutrally.
*** Audio professionals work in rooms with about 250 ms reverberation time or with headphones, because they listen analytically and for specific details when they produce a recording. They traditionally use loudspeakers that interact with a room in a perceptually unfriendly way and so they must use a room that is highly damped. This increases the ratio of direct to room reverberated sound, which is equivalent to sitting closer to the speaker. ***
用这个计算器算算自己的房间,看看6毫秒后,还剩多大的面积吧
