I will qualify that I haven't read the book yet. Just glancing through it after it arrived was disappointing. The book has three sections. Section one is "Test and Measurement" by Pat Brown, and is 48 pages long. It looks like a good overview of testing, much like he offers in the SynAudCon classes.
Section two is "What's the Ear for? How to protect it". It is 25 pages long and while it looks valid, wasn't what I expected in this title. Section three is Fundamentals and Units of Measurement. It is about 100 pages of charts covering everything form the SI system (wow I didn't know octillion is the name of a number, that makes my life richer), to some basic one paragraph topics on basic physics, some good formulas and charts for audio usage, on to the greek alphabet, ISO standard numbers, abbreviations for 30 pages (XLPE is cross linked polyethelene), to some geometry reveiw. It is factual filler.
It appears the content is good, but basic. It was not an in depth book on A Sound Engineers Guide to Audio test and Measurement in my opinion. There are other books that cover this better. In fact this book appears to be three chapters out of Handbook for Sound Engineers. I didn't look for updates. It looks nearly identical.
My rating is low because this is a rehash of a portion another book and the content does not follow the title very well.
