Kinsler, Frey, Coppens, and Sanders, Fundamentals of Acoustics (same as used in ECE 473)
Course Notes and journal articles
Readings
Fundamentals of Acoustics by Kinsler et al.
Chapter 1: simple vibrator/oscillator frequency and time response (lecture 2)
Chapter 1: linear combinations of sinusoids and Fourier sound analysis (lecture 3)
Chapter 5: acoustic wave equation, plane waves with reflection, sound pressure and intensity level (decibels) (lecture 4)
Chapter 5: spherical waves; Chapter 7: vibrating piston radiation pattern and impedance (lectures 5,6)
Chapter 9: rectangular cavity; Chapter 12: architectural acoustics: all sections (lectures 6-8)
plus 1965, 1970, 1974, and 1996 journal articles by M. R. Schroeder (see Secure Area) (lectures 9-10)
Chapter 14: moving coil loudspeakers and loudspeaker cabinets (lectures 11-14)
Chapter 14: microphones: electrostatic and electromagnetic; pressure and gradient (lectures 16-19)
Notes Part 1 on Acoustics Review; Auditoriums & Rooms; Loudspeakers & Enclosures (available at ECE Storeroom).
Notes Part 2 on Microphones; Spatial Hearing & Sound Localization; Artificial Reverberation (available at ECE Storeroom).
Kinsler et al., Chapter 11, pp. 312 - 327: the ear, thresholds, equal loudness level contours, critical bandwidth, masking, loudness level and loudness, pitch and frequency.
In the Secure area: journal papers on Digital Audio by Barry Blesser (1978), Robert Maher (1992), John Vanderkeey & Stanley Lipshitz (1984), Max Houser (1991), and Karlheinz Brandenburg and Marina Bosi (1995); and on psychoacoustics by Eberhard and Tilmann Zwicker (1991).
In the Lectures and Notes area: Lectures 27 - 35 and Prof. Hasegawa-Johnson notes, Chapters 9 (loudness and masking), 10 (pitch), and 11 (audio coding, sections 11.4-11.9 only). Lecture 36 gives a review list of topics for the course.
