Online Training: Basic Sequence Writing (European Schedule)

/in /by

Sept 23 at 3pm Central European Time, 2pm UK time, 9am US (East Coast) time [Note: rescheduled from original date of Sept 8th]

The ability to quickly generate test sequences is one of the most powerful SoundCheck skills you can acquire. We are bringing a 2 hour basic sequence writing course to the comfort of your own home with our new online training at a convenient time for our European customers.

This 2 hour course is a condensed version of the basics of sequence writing from our popular 2 day training class. We will start from the beginning, explaining how to determine the test parameters and hardware that will meet your specific test requirements. We will look at best practices for creating a sequence, and finally we will assemble a sequence from scratch. This course is ideal for novice SoundCheck users, or those who have been using SoundCheck with sequences that others have written and who are ready to start developing their own. This training is free to support contract holders and US $79 for others.

Listen公司的SoundCheck电声测试系统广泛用于全球领先的原始设备制造商及其合约制造商的成千上万条生产线。虽然它可以用于测试各种各样的设备，包括扬声器、微型扬声器、耳机、耳麦、智能设备、手机等等，但本次研讨会将着重讨论耳机。

在这次在线研讨会中，Steve Temme先生将涵盖耳机测试的基础知识，包括：

  • 耳机的工作原理
  • 如何测试耳机（包括不同种类的耳机和声学耳模拟器）
  • 研发和产线测试的环境
  • 重要的测试如校正的频率响应、左右声道平衡度、失真等等。

 

In this 60 minute online seminar, S&V Samford presents Listen, Inc. founder and president, Steve Temme, discussing Headphone Measurement Basics.

Listen, Inc’s SoundCheck electroacoustic test system is used by the world’s leading OEMs and their contract manufacturers on thousands of production lines worldwide. Although it can be used for testing a wide range of devices including speakers, microspeakers, headphones, headsets, smart devices, cellphones and more, this seminar will focus on headphones.

In this online session, Steve Temme will cover the basics of headphone testing, including:

  • How a headphone works
  • How to measure headphones (including considerations for different types of headphones, and acoustic ear simulators)
  • R&D and production test environments
  • Important measurements such as corrected frequency response, left/right tracking, distortion etc.

Remote Training

/in /by

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.

 

Audio Testing with SoundCheck at Sound Hub Denmark

/in , /by

February 25th, 2020. 8.30-17.00

Learn how to measure audio quality of both simple and complex modern audio devices, in both R&D and production environments. Get to know the basics of SoundCheck; one of the world’s most popular audio test software systems, and learn about how to build a test sequence incl. recommendations for the equipment used. Additionally, you will get familiar with specific methods and conditions applied for voice-activated audio testing for e.g. automotive among others.

Join us for an inspiring day, where the Founder and President of Listen, Inc., Steve Temme from US together with Danish representatives and people from GRAS share knowledge about do’s and don’ts.

Sound Hub Denmark has the software and recommended equipment in house to further assist you after this course.

Program Outline

8.30–9.00: Sign-in & welcome

9.00-12.00: Audio Measurement Basics: What to measure and why

  • Learn about different test configurations and the products you need for a test system (software, microphones, interfaces, chambers etc.)
  • Understand the basics of SoundCheck – one of the  world’s most popular audio test systems used on over 10,000 production lines worldwide
  • Learn how to build a simple test sequence for speakers and microphones in SoundCheck, and how to adapt this for different products
  • Common challenges and pitfalls with audio testing
  • Transitioning test from the R&D lab to the production line

12.30: Light lunch

13.15-16.00: Voice-Activated Device Testing, Automotive, smart speakers, hearables

  • Automotive infotainment systems, hearables, smart speakers and many other audio devices are now voice-activated. Such devices are complex to test as they have numerous wired and wireless connections and often contain signal processing, both on the record and the playback side. This means that their characteristics change according to ‘real world’ conditions of the environment that they are used in, such as automotive cabin and roaad noise, background noise, playback levels, and room acoustics. Furthermore, many aspects of the device may need to be tested, ranging from voice recognition to music playback, operation as a hands-free telephone, and even hearing assistance. Often measurements need to be made at different levels and different environmental conditions. In this session, we will discuss the test configurations, tools and techniques that enable accurate measurement of the audio performance of such devices under the many various real-world conditions in which they are used.

16.00-17.00: Hands on and drinks

Space is limited so please sign up on the event page on the Sound Hub Website.

Recall Tutorial

/in , /by

A new series of 3 short videos guides the user through SoundCheck’s various recall capabilities. SoundCheck’s ‘recall’ functionality allows previously saved data to be brought back into SoundCheck where it may be used in test sequences, for example data from a golden unit, weighting/correction curves or limit curves.
The first video covers the basics, and the other two focus on recalling text files and wave files respectively.

Recall 1: The Basics
Recall 2: Recalling Text Files
Recall 3: Recalling Wave Files

Autosave Tutorial

/in , /by

This series of 6 training videos explains how to autosave data from SoundCheck in a variety of formats. The first video covers the basics, and the subsequent ones discuss the various autosave formats in more details.

Autosave 1: The Basics
Autosave 2: Autosave to Database
Autosave 3: Autosave to Excel
Autosave 4: Autosave to Matlab
Autosave 5: Autosave to Text
