A Simple Sound Wave

A Simple Sound Wave

Question 1 of 10

1

What is the name of the auditory stimulus in its most basic form?

Select one of the following:

  • The sinewave or "pure tone"

  • The coswave or "pure tone"

  • The sinewave or "basic tone"

  • The coswave or "basic tone"

Explanation

Question 2 of 10

1

What are the three principle elements that contribute to variations in sound?

Select one of the following:

  • Frequency, amplitude and phase

  • Frequency, pitch and phase

  • Timbre, amplitude and phase

  • Timbre, rhythm and localisation

Explanation

Question 3 of 10

1

What is frequency?

Select one of the following:

  • 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

Explanation

Question 4 of 10

1

How is frequency measured?

Select one of the following:

  • 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

Explanation

  • Localisation

  • Intensity

Explanation

Question 6 of 10

Select one of the following:

  • 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

Explanation

Explanation

Question 9 of 10

1

What is phase?

Select one of the following:

  • 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.

Explanation
