混响声

在室内声信号采集时，若声源与麦克风距离较远，采集的信号常含有混响声，过大的混响声会严重影响音频信号的清晰度和可懂度。

Audio signals recorded with a distant microphone in a room usually contain reverberation , which degrades the clarity and intelligibility of speech .

已研制成功的具有自动混合功能的八通道控制器样机，能帮助多个传声器拾音的现场自动混合，并能减小反馈、环境噪声和混响声的拾取。

Eight channel controler sample , which has automatic mixing function , can provide automatic mixing in worksite of picked ap by several microphone as well as reduces feeding , circumstances nois (?) and reverberation picking up .

电教用房的室内声音包括直达声、前期反射声和混响声。

The indoor sound in audio-visual room consists of through sound , early reflex sound and the reverberations .

而对于室内混响窗外传声的声影响预测，采用该方法也会使测量和计算变得十分简洁方便。

It also makes works of measuring and calculation very convenient when predicts the impaction of noise which reverberates in a room and penetrates out of windows .

在混响室中测定声功率，方法简单，但在低频率所得结果比自由场值要低。

The determination of the sound power of a source is simple in a reverberation cham-bei , but usually lower values are obtained at low frequencies than the free-space valus .

耦合空间是指厅堂中存在的一些次空间或者附属空间，因为这些空间的存在使厅堂容积扩大而出现混响时间延长、声衰变速度改变等声学特性改变。

Coupled space refers to secondary space or auxiliary space which exists in hall buildings . It changes acoustic characteristic such as reverberation time and sound-energy decay for the extension of building volume .

分析表明了声品质在这类非声学建筑中的重要性，另外，即使客观指标例如声压级和混响时间相同，声舒适度亦可能完全不同。

It is revealed that acoustic quality is an important consideration in these buildings , and it may vary considerably with the same objective acoustic indices such as sound pressure level and reverberation time .
