1·The sound source is placed in a reverberation room, and the receiving room is a small anechoic box.
这种方法,声源放在一个混响室内,而接收室是一个小的消声箱。
2·In the measurement of sound absorption coefficient in random incidence and determination of sound power levels of noise sources, the reverberation room is used very extensively.
混响室是声学专业的实验室用房,它在测量声波无规入射时材料的吸声系数和测量噪声源的声功率级中得到了广泛应用。
3·Reverberation is the persistence of sound in a room after the source has stopped making sound.
回声现象就是在房间中,声源停止发声后,声音仍然持续的现象。
4·These levels come from outside activities that penetrate the classroom structure, from teaching activities, and other noise generated inside, which can be exacerbated by room reverberation.
这些(噪音)可以是穿透教室建筑结构的室外活动声、教学活动的声音以及室内产生的其它各种声响,这些声音都会因为房间的回声效果而被放大。
5·For a single instrument, say something like a piano recital, a room with a short reverberation time is better.
对于单一的乐器,比如钢琴独奏会,一个回声时间短的房间更好。
6·So we'll have to take into account what the room will be mainly used for, since music requires more reverberation than speech.
因为音乐演奏比起演讲来说,更需要回声,所以我们必须考虑房间的主要用途。
7·But besides the size of the room, another variable affecting reverberation is the shape of the room.
除了房间的规模外,房间形状是另一个影响变量。
8·In this paper, room sound field theory as the basis of measurement based on reverberation chamber and waveguide theory as the basis of measurement based on impedance tube are introduced.
本文介绍了声学特性测量混响室法的基础室内声场理论与阻抗管法的基础管道平面波理论。
9·On Thursday, March 13, 2008, it seemed the acoustics in my room was closed because I could not feel energy (resonance or reverberation) when I sang.
2008年3月13日星期四,我房间里的音响好像被关掉了,因为我唱歌的时候感觉不到能量,缺乏共振回响。
10·Centrifugal glass cotton can be made into wallboard, ceiling, space sound-absorbing body etc, can be absorbed in a room, reduce doubled the reverberation time, reduce indoor noise.
离心玻璃棉可以制成墙板、天花板、空间吸声体等,可以大量吸收房间内的声能,降低混响时间,减少室内噪声。
