Did you know you can make free-field measurements without an anechoic chamber? In the March 2021 issue of VoiceCoil, Steve Temme explains his unique method for achieving this. The article explains how the ‘splice’ method results in a full range frequency response from a combination of near-field and windowed far-field measurement, and compares the results […]
2021年3月17日，上午10点（中国时区） 在本在线研讨会上， 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。 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。 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。
March 4, 2021. 9 am and 2pm Eastern time. Sign up below. 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 […]

This sequence measures the anechoic response of a loudspeaker in an ordinary room using both a near field and time-windowed far field measurement “spliced” together to cover the full bandwidth of the loudspeaker’s response from 20 Hz to 40 kHz. First, the microphone is placed very close to the low frequency driver (less than an inch […]
