I've been quite bored this summer and other than the few landscaping opportunities I've had, there has been nothing to keep me busy. In this boredom, I've begun to fervently pursue learning about physics, acoustics, psychoacoustics, etc in hopes that if I understand the way sound propagates and how humans interpret the information I can create a better loudspeaker system and/or design around the weak spots in the human psyche (for example, below 1khz the phase (time) effect dominates localization while above 1khz the intensity effect dominates, they are both blurry around 2khz which is why that is a good point for a crossover). Anyways, I joined the advancedphysics forums and was recommended some specific reading, Theoretical Acoustics by Philip M. Morse and K. Uno Ingard and Fundamentals of Physical Acoustics by David T. Blackstock. The first book costs $100 and the second book costs $140, as I believe they are graduate study works. I checked with my local library and they have neither in circulation. I'm only 18 and a senior in High School, there is no way I can afford to spend $240 on personal reading. Where could I source some of these books for cheap or near free (I'm so used to be able to check out books for free at the library).
