20-20kHz Free Field Measurements Without an Anechoic Chamber

无需消声室的20-20kH自由场测量

在研讨会上， Steve Temme将解释如何在无需消声室的情況下，使用模拟自由场测量，在整个可听频率范围内提供准确的自由场测量。这样能让通常要在消声室中进行的测量可以在常规实验室甚至家中进行，这是对于当前在家工作的许多人来说是一项非常宝贵功能。

In this online seminar, Steve Temme explains how to use simulated free field measurements to provide accurate free-field measurements across the entire audible frequency range without an anechoic chamber. This enables measurements that would usually be made in an anechoic chamber to be made in a regular lab or even home office – a valuable capability when so many are currently working from home.

此测量方法自2001年以来已在SoundCheck中使用，它可以测量低频下的近场响应和高频下的时间窗口远场测量，并将它们拼接在一起以提供整个频率范围内的响应。

 This measurement method, which has been available in SoundCheck since 2001, measures the near-field response at low frequencies and the time-windowed far-field measurement at higher frequencies, and splices them together to provide the response over the entire frequency range.

在这次研讨会中，我们将解释该方法背后的声学和数学原理，并通过预先编写的（免费的）SoundCheck测试序列演示测试程序，并说明结果与消声室内的测量结果之间的关系。该研讨会不收取任何费用，但需要预先注册。

In this seminar we will explain the acoustics and mathematics behind this method, demonstrate the test procedure with the pre-written (and available free of charge) SoundCheck test sequence, and show how the results correlate to measurements made in an anechoic chamber.

There is no charge for this seminar, but registration is required.
