- SoundCheck 18.1 ReleasedSeptember 14, 2020 - 7:27 pm
SoundCheck 18.1 is now available. This update to version 18 includes a couple of new features and several bug-fixes. It introduces control for the upcoming AmpConnect 621 interface, an all-in-one multichannel interface (6-in, 2-out) that is exclusively controlled via the software for seamless integration with test sequences and virtual instruments. It also includes the new […]
- Listen Celebrates 25 YearsSeptember 11, 2020 - 1:21 am
2020 is Listen’s 25th anniversary! When Listen sold its first product in 1995, it was the first soundcard-based audio measurement system, and its competition was often human listeners. Now, with an installed base of well over 10,000 systems and the industry-wide adoption of both soundcard-based architecture and highly automated sequence-based measurement, Listen is still leading […]

- 无需消声室的20-20kHz自由场测量 / 20-20kHz Free Field Measurements Without an Anechoic ChamberFebruary 25, 2021 - 6:39 pm
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。
- 20-20kHz Free Field Measurements Without an Anechoic ChamberFebruary 23, 2021 - 8:09 pm
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 […]

- Statistics TutorialSeptember 8, 2020 - 7:36 pm
Our series of instructional training videos continues with this series of 4 short videos explaining Statistics. These introduce the user to the statistics options in SoundCheck, and demonstrate how to use them in 4 different ways: in sequences, with results, Process Capability measurements, and offline statistics. Statistics 1: Data Statistics 2: Results Statistics 3: Process […]
- Limits TutorialMay 19, 2020 - 7:54 pm
This series of 3 short videos explains how to set up limits in SoundCheck from basic fixed and floating limits to advanced limits that use recalled curves and values from the memory list. Limits 1: The Basics Limits 2: Data Limits 3: Advanced

- Anechoic Response of a Loudspeaker Without an Anechoic Chamber: Splice SequenceNovember 12, 2020 - 7:52 pm
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 […]
- Comparison of effect of different masks on speech distortionSeptember 9, 2020 - 9:58 pm
The purpose of this sequence is to compare the response of an artificial mouth when face masks of different construction are mounted on the mouth. The sequence assumes a lightweight disposable mask and a heavy multi-layer cloth mask. A stepped sinewave from 10 kHz – 100 Hz is played from the unoccluded mouth and the […]
