I wish I'd had this book when I started my masters in audiology (NZ). It would have made my life so much easier! Of all the textbooks covering physics (including sound digitization and electronic circuitry) for student audiologists, this one stands head and shoulders above the rest. The authors designed the book to fill in gaps for audiology students who lack or need to brush up on the sciences required for postgrad audiology courses (particularly physics and maths). They certainly deliver on their promise of making complex concepts simple to understand without dumbing down the content. They talk though the mathematics step by step (wonderful for those of us who struggle with numbers) and even managed to demystify impedance for me - which, after months of struggling, I didn't think was possible. I'm not sure how it would be to read this book independently from a course, but it is so complete and self-explanatory, I imagine it would be fine. For anyone struggling in a physics for audiology course it is absolutely invaluable and could save you hours of frustration. Well worth the price.
