Due to popular demand, we are now holding our headphone testing seminar in Seoul!

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 speakers Dr. Sean Olive (Harman International) and Prof. Lee (New Media Communication Joint Institute of Seoul National University) 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. Space is limited, so please RSVP today.

Location and Dates:

Seoul: Tuesday March 6th, 2018. Korea National University, 1 Gwanak-ro, Gwanak-gu, Seoul.

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
• Practical examples of headphone measurements on.
  • Analog Headphones
  • Bluetooth Headsets
  • ANC Headphones
  • Lightning/USB Connected Headphones (using triggered recordings)
  • Hi-Res 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
• Design & sound tuning of earphones  (Guest Speaker Prof. Lee, New Media Communication Joint Institute of Seoul National University)
• 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
