With so much more to discuss than we could get to last week, host Scott Wilkinson continues his conversation with Paul Hales, founder of Pro Audio Technology. This week, he explains why he believes that audio science is relatively unrefined, leading to lots of dogma, misinformation, uncertainty, and inconsistency. Next, we dive into immersive-audio systems, including the importance of multiple subs, sophisticated bass management, and speaker directivity. Also, we talk about measuring sound pressure levels, answers to chatroom questions, and more.
