Exam 1 Part 11 (Jeopardy Game) Flashcards
What is the formula for wavelength?
(constant of speech of sound) / (frequency)
What is the formula for frequency?
(number of cycles) / (1 second)
This is the type of wave when air molecules vibrate and move away from then back toward the source again.
Longitudinal wave
A sound source set into vibration with an irregular oscillation pattern will have this type of waveform.
Aperiodic
A fork that vibrates with frequency of 50Hz has a period of this duration.
.02 seconds, 200 milliseconds
This is the landmark in a spectrogram that indicates voicing?
Low energy frication (i.e., between 0-200Hz)
This is what happens to the glottis when producing aspiration.
Glottis opens and the vocal folds spread apart but constricted slightly creating turbulent airflow
In terms of the spectrogram representation, what are two characteristic of an event that would indicate it to be a vowel
High amplitude, low frequency
The spectrogram, spectrum, waveform and speech recording of the speech signal can be evaluated based upon these five characteristics.
Resemblance, elucidation, amplification, arbitrary augmentation and reduction/loss
The first and second formants are relatively far apart from one another for this peripheral vowel.
[i]
This is the type of resonator produced by the human vocal apparatus
Quarter resonator
The first harmonic and the sound source have this in common.
Fundamental frequency
These interactions can take place regarding an incident wave (4)
Reflection, refraction, diffraction, absorption
The type of vibration that occurs when one tuning fork sets another one into vibration.
Forced vibration
This is another name for a standard reference sound.
Threshold of hearing
