Which term refers to the number of cycles per second of a sound wave?
Intensity
Amplitude
Frequency
Phase
The unit of frequency is:
Hertz (Hz)
Decibel (dB)
Newton (N)
Joule (J)
Amplitude corresponds perceptually to:
Timbre
Pitch
Loudness
Duration
Frequency corresponds perceptually to:
Duration
Loudness
Quality
Pitch
Complex sounds are made up of:
Silence
A single frequency
Only aperiodic waves
Multiple frequencies (harmonics)
When two sound waves combine and increase amplitude, this is called:
Destructive interference
Constructive interference
Attenuation
Resonance
A simple harmonic motion produces which type of wave?
Sine wave
Tansverse
Longitudinal
Complex
In vowels, the formant primarily related to tongue height is:
F1
F2
F3
F0
The formant primarily related to tongue advancement is:
F3
F1
F0
F2
As the tongue height decreases, F1 generally:
Disappears
Decreases
Stays constant
Increases
Which acoustic cue best distinguishes voiced from voiceless stops?
Nasal murmur
Voice onset time (VOT)
Intensity contour
Formant transitions
Which of the following sounds shows a voice bar on a spectrogram?
/p/
/t/
/k/
/b/
Nasal consonants are characterized acoustically by:
Long VOT
High frequency energy
Antiformants and nasal murmur
Burst noise
Fricatives show which visual pattern on a spectrogram?
Periodic vertical striations
Random high-frequency noise
Low-frequency bands
Distinct formant transitions
Stops are acoustically identified by:
Continuous noise
Steady-state formants
Nasal murmur
Silence followed by burst release
The fundamental frequency (F0) corresponds to:
The first formant
The intensity of speech
The rate of vocal fold vibration
The loudest harmonic
