The third edition of the book is quite updated including developments in the last few years.The book is published recently but it's based primarily on research from the 80's and 90's.
That aside, objective modelling of audible non-linearities is a hard problem. People love to invent new metrics they hope will make them famous. But ultimately, it is not easy to solve. To wit, every lossy encoder has a perceptual model of hearing to control its encoding parameters yet listening tests rule to determine level of audibility. For a first level estimation, PSNR and such are used as quick shortcuts.
The other challenge for us risk of damaging speakers that are loaned. Problems arise at very high SPLs and Klippel tests have inputs for voice coil temps and such to avoid destruction.
