What is the name of the auditory stimulus in its most basic form?
The sinewave or "pure tone"
The coswave or "pure tone"
The sinewave or "basic tone"
The coswave or "basic tone"
What are the three principle elements that contribute to variations in sound?
Frequency, amplitude and phase
Frequency, pitch and phase
Timbre, amplitude and phase
Timbre, rhythm and localisation
What is frequency?
The duration it takes for a single pressure change to occur
The rate at which action potentials fire in the primary auditory cortex
The rate at which pressure changes are propagated
The duration it takes for a single action potential to fire in the primary auditory cortex
How is frequency measured?
In Hertz (Hz) i.e. the number of cycles per second
In deciBels (dB) i.e. the number of cycles per second
In Hertz (Hz) i.e. the intensity of the compression and rarefaction
In deciBels (dB) i.e. the intensity of the compression and rarefaction
What sound element does frequency determine?
Loudness
Pitch
Localisation
Intensity
What is amplitude?
The difference between the maximum pressure and the atmospheric pressure
The difference between minimum pressure and atmospheric pressure
The difference between maximum pressure and minimum pressure
The combination of maximum pressure and atmospheric pressure
How is amplitude expressed/measured?
Percentage
Mel
Hertz (Hz)
deciBels (dB)
What sound element does amplitude determine?
Timbre
What is phase?
The angle in degrees between the maximum and minimum points in the wave cycle.
The angle in degrees at a specific point in the wave cycle.
The frequency in Hz at a specific point in the wave cycle.
The frequency in Hz between the maximum and minimum points in the wave cycle.
What two elements of sound does phase contribute to?
Loudness and pitch
Loudness and localisation
Timbre and pitch
Timbre and localisation
