I have an undergrad in EE, so the basics are not any issue with me. There is some refresher I need (the whole use it or lose it problem), but there is quite a bit of practical knowledge that is never taught in engineering school, especially related to outside disciplines such as acoutical engineering.Part of teh problem is that there is so much out there that it is hard to determine what is going to be useful and what isn't. Since my schedule doesn't allow me to do 'total immersion' in teh subject, I was looking for some good places to start.
