This application note provides an 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. These measurements also apply also to headsets, but only insofar as they are used as headphones.
Due to the close coupling of earphones to the ears and the acoustic transmission paths involved, headphone measurements are complicated. This application note discusses these challenges, types of headphones, measurement standards, headphone acoustics, acoustic test fixtures required for measuring headphones, and the practical aspects of headphone measurements. Objective measurements are also reviewed.

The following electroacoustic headphone measurements are covered in this application note:
·         Frequency Response
·         Electrical Impedance
·         Input voltages
·         Sound Pressure Level
·         Distortion
·         Noise Attenuation
·         Crosstalk Attenuation
