Production Testing Seminar

March 10th, 2022. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)

In this short seminar, Les Quindipan explores the use of SoundCheck for end-of-line production testing. He discusses typical test configurations and the type of measurements that can be made, how to set pass/fail limits and how to optimize tests for high throughput.

He will also explain how SoundCheck is easily scaled for high volume production testing, with such features as external control via another program and auto-saving data to databases, and how SoundCheck’s capabilities are easily expanded through the use of custom steps to control all types of devices and test fixtures.

This seminar will be of interest to anyone considering a production line implementation of SoundCheck, or curious as to how to transition R&D measurements to fast and effective end-of-line test.

Note: We will be repeating this seminar in conjunction with our exclusive distributor in China, S&V Samford, a sign-up will be available shortly.

Basic Loudspeaker Measurement Seminar

Sept 30th, 2021. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)

Join Les Quindipan and Anastassia Tolpygo on Sept 30th for a seminar on basic loudspeaker testing. This introductory seminar is aimed at anyone new to audio measurement, specifically loudspeaker testing. It will begin with an introduction to the basic design of a loudspeaker, including how a typical loudspeaker works. Various loudspeaker measurements will be explained, such as frequency response, distortion, sensitivity, phase/polarity and impedance, and how they might offer indications as to potential defects in a speaker. Typical test configurations for both R&D and end-of-line production test will be shown. A complete speaker test will be demonstrated, using SoundCheck and our free Loudspeaker complete test sequence. This will include setting up software and hardware, calibrating and configuring the test (e.g. setting pass/fail limits) and a discussion of the results. There is no charge for this seminar, but registration is required.

Note: We will be repeating this seminar in conjunction with our exclusive distributor in China, S&V Samford,  on Oct 13th. Register  for the China seminar if this timing suits you better or you prefer the slides translated into Chinese.

蓝牙音频测试 / Bluetooth Testing Seminar

June 3rd 2021. 10am (China Time)

This seminar has now passed, but you can watch the video.

In this 1hr online seminar, S&V Samford presents Les Quindipan of Listen, Inc. and Kristopher Hett of Portland Tool & Die demonstrating how to test Bluetooth devices.

Kris Hett will introduce the Portland Tool & Die Bluetooth interfaces that are used to connect the device under test to the measurement system. He will discuss the technical specifications, and explain the differences between these and other types of Bluetooth interfaces. Les Quindipan will then demonstrate how these have been fully integrated into SoundCheck for simple plug and play operation, and how they can be used in test sequences. He will also highlight some of the algorithms included in SoundCheck that overcome Bluetooth-induced time delays, thus enabling these devices to be tested in a similar way to their wired counterparts. A complete test on a Bluetooth speaker and a Bluetooth Headset will be demonstrated.

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

无需消声室的20-20kHz自由场测量 / 20-20kHz Free Field Measurements Without an Anechoic Chamber

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 Chamber

This event has now passed, but you can view the video recording here.

 

 

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.

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.

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.
