提出了一种新的方法来获取音乐霍尔斯中的脉冲响应，具有大的信噪比和高分辨率。在我们的建议中，使用了一个全向扬声器，它由一个放大的扫描驱动：一个包含所有感兴趣的频率的信号在时间上模糊。通过使用反褶积技术，获得了具有高峰压力和短有效持续时间的几乎完美的脉冲。在两个不同的音乐霍尔斯进行了测量，以说明新技术的实际意义。
A new method is proposed to acquire impulse responses in concert halls with large signal‐to‐noise ratios and with a high resolution. In our proposal an omnidirectional loudspeaker is used which is driven by an amplified sweep: a signal containing all frequencies of interest smeared out in time. By using a deconvolution technique, an almost perfect pulse is obtained with a high peak pressure and a short effective duration. Measurements were made in two different concert halls to illustrate the practical implications of the new technique.
