What does the fundamental frequency (F0) tell you about a sound?

• The volume of the sound

• The pitch of the sound

• The speed of the sound

• The direction of the sound

What does amplitude refer to in sound waves?

• The speed of the wave

• How forceful a wave is

• The length of the wave

• The frequency of the wave

How would a weak oscillation affect the amplitude of a wave?

• It would create a large change in amplitude

• It would cause no change in amplitude

• It would create a tiny change in amplitude

• It would increase the frequency instead

What does a wave with a small amplitude generally sound like?

• Loud

• Quiet

• High-pitched

• Low-pitched

How do people perceive amplitude?

• As frequency

• As loudness

• As pitch

• As duration

Which sense helps humans localize the source of a sound?

• Pitch

• Frequency

• Phase

• Amplitude

What is resonance in the context of speech?

• The production of sound from the vocal folds

• The strengthening or weakening of certain sound frequencies as they pass through a structure

• The creation of harmonics in speech

• The vibration of vocal folds without sound shaping

What happens to sound when it passes through a large structure?

• High sounds are boosted

• Low sounds are boosted

• High sounds are dampened

• All frequencies are equally boosted

Which body parts are involved in shaping sound resonance?

• Vocal folds and larynx

• Lips, tongue, jaw, velum, nose, and throat

• Lungs and diaphragm

• Ears and brain

What are formants in speech?

• The source of sound in the vocal folds

• The fundamental frequency of speech

• Resonant peaks in the sound spectrum

• The speed of air through the vocal tract
