Esto es lo que dice en el libro:

"There is no doubt that such a process can yield improvements at low frequencies for a single listener, but above the transition frequency to claim that a smoothed steady-state room curve derived from an omnidirectional microphone is an adequate substitute for the timbral and spatial perceptions by two ears and brain is absurd."

Refiriéndose a las salas, todas las considera "normales" excepto algunas "aberrant listening room".
