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.
Due to popular demand, we are now holding our headphone testing seminar in Chicago and Boston!
Learn about the latest in headphone test systems and methods from design to EOL Test. Industry experts Steve Temme (Listen, Inc.) and Peter Wulf-Andersen (G.R.A.S.), as well as guest speaker Dr. Sean Olive (Harman International) will discuss test equipment (ear couplers, test fixtures, test software and hardware) and demonstrate practical test setups for both R&D and QC headphone testing. It will cover in-ear monitors, Bluetooth, lightning/USB, noise-cancelling and high resolution headphones, in addition to conventional analog headphones. You can even measure your own headphone using our equipment in the hands-on session. Please see the full agenda below.
There is no charge for this one-day seminar and lunch will be provided. Space is limited, so please RSVP today.
Locations and Dates:
Chicago: Friday October 13th, DoubleTree by Hilton Hotel Chicago Wood Dale-Elk Grove, 1200 N Mittel Blvd, Wood Dale, IL 60191
Boston: Monday October 16th, Hilton Garden Inn, 450 Totten Pond Rd, Waltham, MA 02451NOTE: THIS VENUE HAS CHANGED. DUE TO HIGH DEMAND FOR THIS SEMINAR WE HAVE HAD TO MOVE IT TO A LARGER VENUE. Note that this is 2 days before the start of the AES show in New York – a short flight or 3.5 hour train ride away. Consider combining this informative seminar with your AES travel!

Agenda (9am-4pm)
Introduction
Overview of Headphone Test Systems and tools
Traditional tools vs. modern consumer demands
Introduction to head and ear related terminology and definitions.
Historical perspective and background for the tools and standards used today.
Limitations vs. Possibilities in term of the measurement capabilities. How does that relate to the modern challenges with Bluetooth and ANC related testing tasks?
Tools for Next Generation Headphone Testing
Solutions to some the challenges addressed above.
Examples based on products and measurements.
What about frequencies above 20kHz? Science or marketing? Measurement Consistency – Development vs. Production
Progress in measurements from Head and Torso Simulator (KEMAR) to Production Test Fixture (45CC – flat plate). How the different components affect the measurements:
Software and hardware for headphone testing including typical headphone measurements and test setups
Standards including Max SPL EN-50332 & IEC-60268-7
Headphone Design: Perception and Measurement of Headphones – What is the Preferred Target Response? (Guest Speaker: Dr. Sean Olive, Harman International)
Hands-on testing: Bring your own device and test it using one of our measurement setups

We are excited to announce a new low-cost headphone test package – SoundCheck ONE for headphone testing (part # 1007). This includes SoundCheck ONE, a basic version of the SoundCheck software, along with AudioConnectTM, an audio interface with built-in headphone amplifier. Only a headphone coupler or test fixture and associated power supply is additionally needed to make up a complete headphone test system. The SoundCheck ONE headphone test sequence carries out all basic headphone measurements such as frequency response, sensitivity, THD, Rub & Buzz, Perceptual Rub & Buzz, loose particles, polarity and channel balance. It can be easily customized and saved for specific products by turning individual measurements on and off, and by adjusting settings within each sequence step such as stimulus range and level, tolerance limits, graphical displays, and data saving. It is an excellent low-cost entry level system, ideal for those on a tight budget.
Please note that although the SoundCheck ONE Headphone test sequence cannot have steps added/removed or the layout modified, customers may upgrade to a SoundCheck package that supports this at any time in the future, should testing needs expand to require additional functionality. Listen can also offer the GRAS 45CC headphone test fixture along with a SoundConnect 2 power supply for a complete production line test system.
