Well, we're a bit off topic here, but psychoacoustics is a 
very mature science that studies how humans hear and perceive 
sound. I'm a member of the Acoustical Society of America, and 
that discipline is well represented among our membership. 
Indeed, if you look up Bell Labs original stereo patent (from 
1936) youl'll see references to important psychoacoustic work 
on human perception by some folks at Harvard. 

Bose's best known contribution to home listening is the 
reflecting loudspeaker that bounces sound off the wall behind 
it, with the intent of providing some of the difusion 
inherent in good concert halls. There are better ways to 
achieve a high quality home listening experience, but Bose is 
NOT about heavy bass. 

The various signal processing games that Lyle is playing are 
based on some well known fundamental psychoacoustic 
principles.
