Testing and Using Ear Couplers to Optimize Audio Testing  For years and years personal audio testing was relying on test equipment build for testing hearing aids – however with high definition personal audio equipment and a “normal hearing” customer group, requirements have grown beyond what hearing aid manufacturers desire. The principles and measurement equipment is however still valid – and we will take a look at those ear couplers, as well as where the consumer electronics and hearing aid industries are moving – and what their new test set ups entails.

In this technical session we will explore all aspects of testing using ear couplers:

  • How measurement microphones are made and differs from other microphones.
  • When to use one type over another
  • We will also go through the various coupler types available – and talk about the differences incl. which can be used in testing personal audio products.  
  • Some Tips and tricks in mounting/testing headphones
  • New generation ear simulators which will allow you to measure below the threshold of human hearing
  • New generation pinnae which offer both reproducibility as well as realistic seals

The seminar is focused on measurement techniques and equipment allowing the audience to set up their own measurement system. We will not be offering advice on target curves or what a “good” headphone sounds like – this is up to the individual manufacturer/listener to determine.
