A complex sound consists of more than one:
sinusoidal component of different frequencies
2 of 21
The frequency of a sound wave is measures in what units
Hz
3 of 21
If a sound has a high number of cycles per second, it has a high:
Frequency
4 of 21
The Physical definition of sound states that
sound is pressure changes in the air or other medium caused by the vibrations of an object
5 of 21
What is NOT TRUE?
Sound is not visualised using Rubens' tube
6 of 21
What structure is NOT a part of the outer ear?
Cochlea
7 of 21
Which statement about the tympanic membrane (eardrum) is FALSE
It is a pyramid-shaped membrane separating the outer and middle ear
8 of 21
Which is Not an Ossicle?
Tympanic
9 of 21
What do the Ossicles do?
Amplify the vibrations in ear drum and transmit the vibrations to the inner ear at the oval window
10 of 21
Louder sounds tend to produce:
Higher firing rates in auditory nerve fibres
11 of 21

Cochlea
12 of 21
What is NOT TRUE about Auditory Transduction?
Changes in pressure propagates up and down its spiral structure
13 of 21
An increase in 20 dB corresponds to what increase in amplitude?
10- fold increase
14 of 21
What is rate code?
Sound amplitude is coded in the firing rate of auditory nerve fibres
15 of 21
What enables us to discriminate loudness across a range of sound levels?
The fact that some fibres have high spontaneous rates and saturate rapidly and some have low spontaneous rates and saturate slowly

What is TRUE in the relationship of loudness and frequency?
Higher decibels are needed at higher frequencies to have equal loudness

Responses increase with increasing sound intensity
