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.

于10 月 13 日加入Les Quindipan 和 Anastassia Tolpygo主持的有关基础扬声器测试的研讨会吧。

此研讨会目的是向任何不熟悉音频测量的人介绍一下音频测量, 特别是扬声器测试。在研讨会中,首先会介绍扬声器的基本设计, 包括典型扬声器的工作原理。并将解释各种扬声器测量,例如频率响应、失真、灵敏度、相位/极性和阻抗, 以及扬声器测试如何提供有关扬声器潜在缺陷的指示。研讨会将展示用于研发和下线生产测试的典型测试配置。

在研讨会中将演示完整的扬声器测试。使用 SoundCheck 和我们免费的扬声器完整测试程序。这将包括设置软件和硬件、校准和配置测试(例如设置通过/失败限制)以及对结果的讨论。本次研讨会不收取任何费用,但需要预先报名。

Bluetooth Device Measurement Seminar

This event has already taken place, but you can view the recording here.

 

May 27th, 2021. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)

In this 1hr online seminar, Les Quindipan of Listen, Inc. and Kristopher Hett of Portland Tool & Die demonstrate 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.

Note: We are repeating this seminar in conjunction with our exclusive distributor in China, S&V Samford,  on June 3rd at 10.00am China time. Please register for this seminar instead if this timing suits you better or you prefer the slides translated into Chinese.

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。

Remote Training

Due to the current COVID-19 situation, we are not offering in-person group training classes. These will be resumed when regulations allow and there is the demand for it.

In the meantime, we offer customized online training for groups of people from the same company, and can offer flexibility in timing, session length and schedule. Please contact your sales engineer for more information.

Additionally, we will shortly be announcing some scheduled online training classes and these will be posted here as soon as information is available.

 

Don’t forget to check out our collection of Working from Home with SoundCheck videos on our Youtube channel. Our support team has created this series of videos that demonstrate features of SoundCheck that can easily be explored offline without full access to your lab.

If you are a new user, our series of on-demand training videos is a good place to start. These cover much of the content from day 1 of our basic 2 day training.
