| # | Date | Topics | Reading | Homework due | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 1 | Tu Sep 1 | Welcome! Familiarize yourself with the syllabus and do Participation #1; Physics Phundamentals (spacetime, like, wow) Basic plots of amplitude vs. time and amplitude vs. position. Simple Harmonic Motion | Ch. 1 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 2 | Th Sep 3 | Phundamentals continued... Prefixes, units and scientific notation, oh my! Sound is a wave: waves have amplitude, period, frequency, wavelength and shape... what does all that mean? amplitude=volume, frequency=pitch, waveform=timbre=tone quality=wave shape, etc.), phase...hmmm, phase=? | § 1.1-1.3 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 3 | Tu Sep 8 | Damping, driving, forced oscillations, beats, resonance coupling, wavelength, travelling waves! It sounds kinky. Well, no, it's a slinky (bad joke). | 1.3-1.4, 2.4-2.5 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 4 | Th Sep 10* | What determines the velocity of a wave? The period? The frequency? The wavelength? How fast is the (velocity) speed of sound? Dissipation is not the opposite of constipation. | 2.1-2.3 | HW #1 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 5 | Tu Sep 15 | Dissipation, Huygen's wavelets; reflection, refraction, diffraction | 2.4-2.6 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 6 | Th Sep 17 | interference, Doppler shift, supersonic, sonar, infrasonic, ultrasonic, range of human hearing (20 Hz to 20 kHz) | 2.7-2.9 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 7 | Tu Sep 22 | standing waves! | 3.1 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 8 | Th Sep 24 | standing waves, nodes/antinodes (again!), overtone series on a string, harmonic fundamentalism (basic music theory), string instruments, taste of Mersenne's laws | 3.2 | HW #2 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 17 | Tu Nov 3 | binaural effects; diplacusis; hearing loss; cochlear implants | Ch 6.6-6.11 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 18 | Th Nov 5† | We begin temperament; Pythagorean; wolf fifth | Ch 9 | | 19 | Tu Nov 10

| Ch 9 | HW #5
| 20 | Th Nov 12
| Acoustics in one day! (Not as crazy as it sounds)
| Ch 8 |
| 21 | Tu Nov 17
| instruments...start with tubes: three things to consider: 1) source of noise, 2) size & shape of bore, 3) fingerholes. 1) consider edge tones = fipple, blowing across the embouchure: flutes, recorders;
| Ch 10 |
| 22 | Th Nov 19
