I'm looking for information about accoustics and, wait for it, acousticians. How does one train for this? Is it a branch of engineering? Does it entail studying architecture? Music? I've found only very general information or, on the other hand, very technical stuff. I'm looking to be able to ask an acoustician some (mildly) intelligent questions about his work for a broadcast. Any web resources you can think of would be really appreciated. Thanks!
