Fundamentals of Headphone Electroacoustic Measurements
Due to the close coupling of earphones to the ears and the acoustic transmission paths involved, headphone measurements are complicated. This 26-page application note discusses these challenges, headphone types, measurement standards, headphone acoustics, acoustic test fixtures required for measuring headphones, and the practical aspects of headphone measurements. An overview of the key electroacoustic measurements used to characterize the audio quality of headphones and earphones is also provided.
