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 Chris Struck 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:

Seattle: Monday Feb 27th, Embassy Suites Bellevue

Silicon Valley: Wednesday March 1st, Embassy Suites Santa Clara

Los Angeles: Friday March 3rd, Embassy Suites Glendale

 

Agenda (9am-4pm) – UPDATED

  • 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
  • Practical examples of headphone measurements on.
    • Analog Headphones
