The Yamaha Sound Reinforcement Handbook
This is basically the soundman's bible. Sold for an aspiring live sound engineer, has much more than just advice for live sound guys - covering everything from microphones to acoustics to basic electronics to handy rules of thumb to MIDI, all written to be relentlessly pragmatic. It even has a handy appendix covering logarithms.
This isn't the book to give you the final "20%" of knowledge on anything it covers - but it will help you on your way to the first 80% a lot more quickly than most other writing on anything related to semi/pro audio, and pretty much every expert in the field is at least familiar with it, if they don't own a copy.
There seem to be plenty of people interested in music and audio around here, so hopefully someone finds the unusual reference useful.
I would recommend instead finding a well reputed mixing/mastering engineer who offers lessons and pay for some. Bring them your best mix (in the DAW on your laptop) ask them where it is wrong and how to improve it. Shouldn't take more than a couple of hours. In my case this cost around £100 (http://oood.net/mastering/about-stooodio-mastering) and helped enormously. My friends now think I'm great at "mastering" by which they mean mixing, I have nothing even approaching mastering engineer ears & I suspect Colin still wouldn't think much of my mixes either but that's why I'll happily pay him to master them if I ever have time for music again :)
I know there are online practical courses these days, in theory these could be better than a book as they would have audio/interactive examples. No idea if they actually are any good though.
Or if object X (e.g. speaker cone) moves through air with velocity v(t), what will the sound be like at position P?
