Designing Better Headphones with Paul Barton

Designing Better Headphones with Paul Barton

Paul Barton, founder and chief designer for PSB Speakers, talks about his and others' research into human hearing and acoustics to support the effort to establish a "target function" that adds a consistent "room feel" to the sound of headphones.
