ACOUSTICS LAB
CLASS CODE: PH 167L CREDITS:  1
DIVISION: PHYSICAL SCIENCE & ENGINEERING
DEPARTMENT: PHYSICS
GENERAL EDUCATION: This course fulfills a General Education - Physical Science requirement.

DESCRIPTION: This lab addresses basic measurements, vibrations, wave properties, perception and measurement, room properties. Emphasis is placed on the experience, reasoning, and observations that support understanding in the course.
Must be taken concurrently with PH 167.
TAUGHT: Fall, Winter, Summer
CONTENT AND TOPICS: Basic measurement tools and procedures, significant digits and precision. Properties of vibrating systems. Measuring vibrations and waves. Wave properties: wave lengths, wave speeds, wave frequencies, reflection and boundary conditions, standing waves in springs and air columns. Simple and complex wave forms, spectra and Fourier analysis, wave synthesis. If time and student interest allow, some topics may be selected from : Musical intervals, Perception and measurement, and Room properties.
GOALS AND OBJECTIVES: 1.Experience and understand basic physical fundamentals and the key vocabulary to describe it:Oscillations, Wave properties, Types of waves, Wave interference, Synthesis of waves, Standing waves, Complex waves (superposition)
2.Apply understanding of the physical processes above to: musical instruments, the process of hearing sound and how the ear works, the process of perceiving sound*, musical scales and harmony, understanding hearing impairments, the effects of listening environments on sound*, the production of speech.
3.Identify: parts of the ear, parts of the vocal mechanism, effect of each part of vocal mechanism on speech and singing*
4.Experience:*the difference between sound levels, the parts of complex sound individually
5.Perform basic calculations and solve problems with:Newton’s Laws, Inverse square law, Sound Pressure levels (dB), Total Absorption, Reverberation Time, Graphically create the sum of several simple waveforms*
REQUIREMENTS: Lecture, quizzes, homework, exams, laboratory reports, demonstrations, group activities, laboratory activities.
