1
Q

Refers to the periodic sinusoidal oscillation/motion of an object

A

Simple harmonic motion

2
Q

What is an example of a simple harmonic motion?

A

Pendulum, mass spring oscillator, tuning fork

3
Q

What are ways that pressure can be measured in?

A

Amplitude, intensity, displacement, decibels, volts

4
Q

Wave that is periodic (repeats), single frequency and sounds like a pure tone

A

Simple wave

5
Q

Wave that is periodic or aperiodic, multiple frequencies, and may sound tonal or not

A

Complex wave

6
Q

All complex sounds can be broken down into their pure tone components

A

Ohm’s law of acoustics

7
Q

lowest frequency pure tone component present in a complex periodic sound

A

Fundamental frequency

8
Q

integer multiples of f0

A

Harmonic

9
Q

any frequency greater than f0

A

Overtone

10
Q

successive doubling of frequency

A

Octave

11
Q

a complex waveform can be broken down (analyzed) into it’s pure tone components; want to know what pure tones are in the complex waveform

A

Fourier analysis

12
Q

a complex waveform can be formed (synthesized) by combining pure tone components

A

Fourier synthesis

13
Q

Two waves are exactly the same (frequency, amplitude, & phase)
→ the amplitude doubles

A

Perfect summation

14
Q

Two waves are exactly the same (frequency & amplitude) but 180 degrees of phase difference
→ No sound because they are cancelled out, which is a basic noise cancellation technique

A

Perfect cancellation
