[This book] is also an essential stepping stone into additional topics through the extensive references section provided from the research done by Toole and the industry community at large." - Brian Long, Journal of the Audio Engineering Society
Floyd E. Toole is a consultant for Harman and a Fellow of the AES, the Acoustical Society of America and CEDIA, and is in the Consumer Technology Hall of Fame.

Controlling the Variables in Subjective Evaluations Controlling the Physical Variables The Listening Room Making Tests Blind Real-time Loudspeaker Comparison Methods Binaural Record/Replay Loudspeaker Comparisons Listener Position and Seating Relative Loudness Absolute Loudness Playback Sound Levels Choosing Program Material Power Amplifiers, Wire and So Forth Controlling the Psychological Variables How to do the Test Is it preference or accuracy that is evaluated? Chapter 4: The Perceptual and Physical Dimensions of Sound The Frequency Domain The Amplitude Domain Amplitude and Frequency Together: Frequency Response Amplitude and Frequency Together: Equal-Loudness Contours Loudness Controls and Tone Controls Do They Work, Are They necessary? The Boundaries of What We Can Hear What Is Acceptable Background Noise? Linear Distortions: Amplitute and Phase vs. Frequency Spectral Tilt Resonances Viewed in Frequency and Time Finding and Fixing Resonances A Persistent Problem: Differentiating Between Evidence of Resonances and Acoustical Interference Critical bands, ERBNs, and the "resolution" of the hearing system Amplitude, Frequency and Time Together: Waterfall Diagrams Phase and Polarity Do We Hear Waveforms? The Audibility of Phase Shift and Group Delay Phase Shift at Low Frequencies: a Special Case The Audibility of Absolute Polarity Non-Linear Distortions Wavelength, the Key to Understanding Much in Audio Loudspeaker Directivity Room Resonance Basics Resistive/Porous Absorbers and Membrane/Diaphragmatic Absorbers Diffusers and Other Sound Scattering Devices Chapter 5: Characterizing Loudspeakers Can We Describe What is Good?
