Midterm (Speech and Hearing Sciences)

Which of the following best describes the "Source-Filter Theory" of speech production?

• A. The brain generates the speech signal, which is then filtered by the ears.

• B. Sound is generated at the vocal folds (source) and shaped by the vocal tract (filter).

• C. Airflow from the lungs is directly shaped into speech sounds without a filter.

• D. Speech sounds are produced entirely by the articulators.

What is the perceptual correlate of frequency?

• Loudness

• Timbre

• Pitch

• Duration

What is the perceptual correlate of intensity?

• Pitch

• Timbre

• Duration

• Loudness

What is the definition of Fundamental Frequency (Fo)?

• The overall intensity of a sound.

• The rate at which the vocal folds vibrate.

• The perceived quality of a sound.

• The resonant frequency of a cavity.

What is the primary function of resonators in speech production?

• A. To initiate vocal fold vibration.

• B. To provide the power for speech.

• C. To filter and modify the sound produced by the vocal folds.

• D. To control articulation.

Which of the following best describes a transducer?

• A device that amplifies sound.

• A device that changes one form of energy into another.

• A device that measures sound intensity.

• A device that produces sound waves.

As the frequency of a sound wave increases, what happens to its wavelength?

• It decreases.

• It increases.

• It remains the same.

• It becomes zero.

What type of scale is the decibel (dB) scale?

• Linear scale

• Absolute scale

• Ratio scale (logarithmic)

• Interval scale

Which of the following is a characteristic of Simple Harmonic Motion (SHM)?

• Irregular vibration patterns.

• Constant acceleration.

• Periodic and sinusoidal vibration.

• Damping over time.

If the force applied to a surface remains constant, how does pressure change if the area over which the force is applied decreases?

• Pressure decreases.

• Pressure increases.

• Pressure remains the same.

• Pressure becomes zero.
