DIRAC是一个有价值的声学测量工具，适用于现场和实验室声学工程师，研究人员和教育机构。用户可以将一个房间的声学效果与另一个房间进行比较，验证音响系统并进行缩尺模型测量。

基于脉冲响应的测量和分析，该工具支持多种测量配置。

当连接到HBK 2255声级计（作为无线麦克风）和/或HBK 2755智能功率放大器（作为无线声源）时，DIRAC支持无线室内声学测量。多通道测量可以使用多个HBK 2255或大多数Windows兼容的多通道声音设备进行。

考虑到背景噪声的影响，可以根据IEC 60268-16标准，通过人工嘴定向扬声器声源或直接注入声音系统，对男性和女性声音进行语音清晰度测量。

与回声源 4720 相结合，可以快速轻松地进行语音清晰度测量。回声源提供DIRAC用于计算不同语音清晰度参数的校准信号。Echo/DIRAC组合还考虑了背景噪声水平。

使用OmniPower 4292-L型声源，可以在单次通过中获取语音信号电平、脉冲响应和背景噪声电平。只需点击几下鼠标，就可以创建STI与源接收器距离图。

DIRAC以最少的测量量为您提供Lp、A、S、Lp、A、S、4、D2、S、STI、rD和rP。
