研讨会：新的增强型散落粒子算法 / Enhanced Loose Particle Algorithm Launch Event

/in /by

2023年6月1日  上午10点（中国时间） |  June 1st 2023. 10am (China Time)

 

请参加Listen最新算法–增强型散落粒子（eLP）的发布研讨会。这种新的算法大大改善了生产线的瞬态失真测量，它提供了高精确度，易于与人类感知相关联，并将瞬态失真假象与谐波失真分开识别，便于故障排除。它也是识别音频设备中嘎嘎作响的按钮，以及汽车嗡嗡声、吱吱声和嘎嘎声（BSR）测量的理想选择。这种新的算法是基于原始研究，并使用了以前没有用于失真测量的技术。请参加这个简短的在线研讨会，由Steve Temme先生进行演示，并详细解释这个算法的工作原理。

 

Join us for a launch seminar for Listen’s latest algorithm, enhanced Loose Particles (eLP). This new algorithm significantly improves production line transient distortion measurement. It offers high accuracy, easy correlation to human perception, and identifies transient distortion artifacts separately from harmonic distortion for easy troubleshooting. It’s also ideal for identifying rattling buttons in audio devices, and automotive Buzz, Squeak and Rattle (BSR) measurements. This new algorithm is based on original research, and uses techniques not previously used for distortion measurement. Join us in this short online seminar for a demonstration by Steve Temme, and a detailed explanation of how this algorithm works.

External Control of SoundCheck Seminar

/in /by

Oct 18th 9am & 2pm Eastern time; November 2nd, 10am China time

SoundCheck has led the way in production line audio measurement for over 25 years with its sophisticated suite of audio measurement algorithms that offer precise measurement, fast throughput, excellent noise immunity, and world-class reliability. However, many audio manufacturing factories are moving towards large, highly customized, integrated test configurations to evaluate products, not only for audio integrity, but often video, visual and other performance defects. This seminar explains how to bring the advantages of SoundCheck into your automated test environment using any programming language compatible with TCP/IP  including C, C+, Python, LabVIEW and more.

We will run through several demonstrations of SoundCheck integration including:

  • Enabling TCP-IP in SoundCheck, and an overview of commands
  • Using external control to open up and run a SoundCheck sequence using a python script, and returning data for use in any application 
  • Changing test parameters via external control, so that test procedures can be simplified by adapting test conditions on the fly for different products
  • Loading, playing and controlling volume of  a test signal on a DUT  using a custom step in a SoundCheck sequence. 
  • Using external control to automatically equalize wave files loaded into SoundCheck via TCP/IP 
  • Using MATLAB with SoundCheck.

Presenters: Mark Latshaw, Pranav Swaroop

July 21st, 2022. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)
July 27th, 10.00am China time

In this practical online seminar, Steve Temme will demonstrate in-car measurement of frequency response, Max SPL, and Buzz, Squeak and Rattle using a Bluetooth connection. He will discuss considerations such as physical setup, infotainment system controls and the measurement parameters. Steve and his colleagues will then discuss connectivity for automotive testing, explaining and demonstrating the various connectivity options including USB drive, Bluetooth and A2B bus. Finally, we’ll take a look at some of the other audio measurements that you can make using SoundCheck, for example active noise cancellation and voice assistance readiness. 

在这个实用的网络研讨会中，Steve Temme 将演示如何使用蓝牙连接进行车内测量，以测量频率响应、最大 SPL 以及异常音。 他将讨论物理设置、信息娱乐系统控制和测量参数等考虑因素。 然后，Steve和他的同事将讨论汽车测试的连接性，解释和演示各种连接选项，包括 USB 驱动器、蓝牙和A2B 总线。 最后，我们将看看其他您可以透过SoundCheck进行的音频测量，例如主动降噪以及voice assistance readiness测量。

Production Testing Seminar

/in /by

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.

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.
