This book is very well explained but lacks that which some may hope for from a book entitled 'The Master Handbook of Acoustics'.
If you are an 'acoustic enthusiast' and a knowledge of acoustic concepts is important to you, then, this would be worth buying - maybe an undergraduate physics/engineering student might also benefit from its approach.
However, if you are someone that wishes to go beyond, getting to the heart of problems like; noise/vibration control and acoustics, you should go for something like Frank Fahy's Engineering Acoustics, Kinsler and Frey, or, if you are up to it!, Pierce...
