PROFESSOR'S STUDY GUIDE: Musical Acoustics, by Donald E. Hall, 3rd edition, (Brooks/Cole, 2002). Phys 1240 (Prof. Holland, Sp08) CHAPTER 4: Here's what I would say if I was just being superficial/using the textbook: Sound propagation: diffraction/reflection, doppler effect, betats Here's what I would have said if trying to be more specific: Define/distinguish reflection, refractin, and diffraction. (Basic level) Understand basic dependence of diffraction on wavelength. Define and explain Doppler effect Define and explain beats. Here's what I say when trying to be specific, operational, AND student- centered. Predict which wave(length) will bend more when coming out of a hole or around a corner Predict how a given sound will bounce from a wall (and decide what

Unformatted text preview: properties of the wave you need) Explain in simple terms the advantage (or disadvantage) to using a small vs a large opening for an instrument, and the use of small (or large) roughness' on the wall Predict the (change in) pitch of sound arising from a moving source, or heard by a moving listener Describe beats, explain how it would be used musically, predict the beat frequency (given details of the two pitches involved). Explain what physical features of a band-shell help improve sound quality for the audience. Predict which of two shell shapes (or position of musicians) would make the sound louder for audience members in various particular spots....
