Related to the number of cycles per second 1 of 21 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 Which structure is located in the inner ear? 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 16 of 21 What factor is needed for a sound to be twice as loud? 3.16 17 of 21 What is TRUE in the relationship of loudness and frequency? Higher decibels are needed at higher frequencies to have equal loudness 18 of 21 What is TRUE in relation to rate code? Responses increase with increasing sound intensity 19 of 21 The missing fundamental illusion DOES NOT state what: the place and timing of stimulation affects our perception of pitch 20 of 21 The pitch of a sound is encoded via which two codes Place code and timing code 21 of 21
Stuff In don't know in one quiz because i am too stressed to put it in separate ones. (L&B = Learning behaviour, M= Memory, L= Language, R= Reason, M&E = Motivation and Emotion, A= Abnormal Psychology) 0.0 / 5
