HTG 346: Audio Science and Immersive Sound  

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.

HTG 345: Rooms, Speakers, and EQ Curves  

Paul Hales, founder of Pro Audio Technology, talks about room correction—or as he prefers to call it, room compensation. Topics include some of his fundamental principles of room EQ, sound directivity from various objects such as violins and speakers, how microphones do not capture sound in the same way that human ears do, how sound interacts with small to medium-sized rooms, target response curves (including the X-curve), how conforming to the X-curve causes the sound to be louder and more harsh than it should be, his suggested modification to the X-curve, answers to chat-room questions, and more.
