seminar

Learn about the latest in headphone test systems and methods, from industry experts Peter Wulf-Andersen (G.R.A.S.) and Steve Temme (Listen, Inc.). Read the agenda and sign up below.

This one-day seminar 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.

Agenda (9am-4pm)

  • 8.30am – Check in and breakfast
  • 9.00am - 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 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

    • In-ear monitors
  • Measurements including:
    • Frequency Response relative to a target response
    • Left/Right tracking
    • Impedance
    • Noise attenuation
    • Distortion including Non-Coherent Distortion
    • Standards including Max SPL EN-50332 & IEC-60268-7
  • Headphone Design (Guest Speaker Chris Struck, CJS Labs)
