External Control of SoundCheck Seminar
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

Detailed Content Information
Perceptual Distortion Measurements: Perceptual distortion measurements enable production line yield to be increased by rejecting only devices with audible Rub & Buzz defects rather than any distortion defects, and Listen’s new enhanced Perceptual Rub & Buzz (ePRB) algorithm is the first to perform even better than the human ear! Through proprietary noise reduction technology and advanced perceptual algorithms, its performance in a noisy factory environment is comparable to the performance of a trained listener under normal listening conditions. Learn more about the science behind this algorithm, see the results, and learn how to implement it in your end-of-line tests.
Accurate Headphone Measurements in Real World Conditions: In this demo-focused session, we will demonstrate how to accurately measure Headphones and Hearing Assistance Devices under real world conditions with real world signals such as speech and music. For example, we will demonstrate, in real time, how to adjust the headphone fit for a proper seal on the head and torso simulator and measure headphone ANC with real background noise with our Multi Signal Real Time Analyzer
New Features in SoundCheck: The newly released SoundCheck 20 is at the forefront of audio measurement with new features for multichannel and communications, increasing its capabilities for audio measurement of smart speakers, infotainment systems, headphones and hearables, and other voice-activated and multichannel devices. In this 30 minute session, we will demonstrate the new features and explain how they are used for testing a variety of audio products and applications.
Free-field Speaker Measurements without an anechoic chamber: Can’t afford or get time in an anechoic chamber? That’s not a problem if you have SoundCheck! In this practical session, we will demonstrate a method first developed by Listen president Steve Temme back in 1993, known as the ‘splice’ technique. This measurement technique is easy to configure and enables you to make highly accurate free-field measurements in an ordinary room, avoiding the expense of an anechoic chamber and enabling measurements in your home or office.

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.
There is no charge for this seminar, but registration is required.
在这个简短的研讨会中，Les Quindipan将 与我们探讨如何使用 SoundCheck 进行生产线末端测试。 他会讨论典型的测试配置和可以进行的测量类型、如何设置通过/失败限制以及如何优化测试以实现高吞吐量。
他还会探讨SoundCheck 如何轻松扩展以进行大批量生产测试，具有通过另一个程序进行外部控制和自动将数据保存到数据库等功能，以及如何通过使用自定义步骤轻松扩展 SoundCheck 的功能来控制所有类型的 设备和测试夹具。
任何考虑在生产线中使用 SoundCheck 的人士，或想知道如何将研发测量转换为快速有效的生产线末端测试的人士都会对此研讨会感兴趣。
本次研讨会不收取任何费用，但需要预先登记。
