A sound quality evaluation system that enables evaluation of sound based on human hearing and psychology

The perception of sound is quantified through calculations of four parameters.
Sound improvement through sound processing using digital filters.
Binaural recording using a dummy head, which closely mimics the characteristics of the human ear.

The sounds around us include both those we find unpleasant and those we do not. Unpleasant sounds are defined as "noise," and research is underway to reduce this noise itself, as well as to make noise as pleasant as possible. Furthermore, some noise emitted by devices is necessary for those who use them.
Because the sounds that humans perceive vary greatly depending on the environment and circumstances, acoustic researchers have recently been employing psychological approaches, and as a result of the publication of numerous research findings, psychoacoustics technology is becoming established.
In light of these circumstances, Ono Ono Sokki has partnered with Neutrik Cortex Instruments, a world-leading manufacturer of sound quality evaluation systems in Germany, to jointly develop three types of the "SQ series" sound quality evaluation system, which quantitatively analyzes how humans perceive sound using four parameters.
