EXOFIELD Feature (2)
Measurement using the industry's first* "in-ear audio microphone system" allows creation of a natural sound field in both open-back and closed-back headphones
JVCKENWOOD developed an ultra compact "in-ear audio microphone system" using a MEMS microphone to measure the individual characteristics of users. Placing an ultra compact microphone system in the ear canal makes it possible to accurately measure head and ear shapes as well as the sound field characteristics of users' ear canals. By enabling users to easily fix the position of the microphone system they are wearing to the ideal measuring point regardless of individual differences in the shape of the ears, stable and highly-accurate measurement is achieved. The result is a listening experience with a natural sound field not only in open-back headphones, but also closed-back headphones for which conventional out-of-head localization was considered relatively ineffective in reproducing natural sound.
"EXOFIELD" Measurement (1) - Speaker characteristics
Measures and analyzes the shape of the ears and face of individuals, as well as all acoustic characteristics including those of the audio speakers and listening room to perform audio signal processing that is optimally customized to individual users.
"EXOFIELD" Measurement (2) - Headphone characteristics
Measures and analyzes the shape of the ears of individuals, as well as acoustic characteristics including those of the headphones while the listener is wearing them to perform audio signal processing that is optimally customized to individual users.
*The first commercially available measurement system for out-of-head localization when listening with headphones based on data as of March 14, 2017 (survey by JVCKENWOOD).
