Hearing Science Study Guide for Exam 1 Use this as a guide for determining the types of things you should know and the level at which you need to understand them. 1. Understand the concept of sound as the propagation of pressure fluctuations through a medium, such as air. What are the names for the low-pressure and high-pressure phases? 2. Draw a sinewave with labeled axes, given the peak amplitude, frequency, and starting phase. 3. Do the reverse of number 1. If given the graph of a sinewave, determine the amplitude, frequency and phase. 4. What do the terms amplitude spectrum and phase spectrum mean? 5. What does the amplitude spectrum of a sinewave look like? How about the spectrum of a complex periodic wave like a square wave? How about the spectrum of an aperiodic noise? How about the spectra of short pulses and sinewaves? Given the drawing of a waveform, you should be able to determine what kind of spectrum the signal should have, and vice versa. 6. Given the spectrum of a complex periodic signal, determine the fundamental frequency.
