An AP Application Note, Headphone Electroacoustic Measurements,
published in 2016, contains a high-level overview of the key electroacoustic measurements used to characterize the audio quality of headphones and earphones intended for listening to music and other full-band audio program material. Users who are less familiar with headphone test or who want more background information might want to start with that document.
In this Technote, we provide a more detailed discussion on the choice of test equipment for headphone testing, as well as detailed instructions on how to conduct the tests with APx audio analyzers. An APx517B acoustic analyzer is the instrument used in the discussion.
Note: An APx project file (named “TN143 Headphone Test APx517 (APxv6.0.1).approjx”) accompanies this Technote and is used to illustrate headphone measurements. The project file was created for an APx517B audio analyzer, but can easily be adapted for use with other APx audio analyzers with appropriate test accessories. |
