Interaural time difference tells us that if the sound source is on the left, the

The maximum ITD is produced for a sound placed at what number of
Exampromax - Stuvia US
degrees from where the observer's head is pointing?
Ans: 90 degrees
It does not matter where in a room you place a low frequency woofer
because low frequency sound bends easily around the head reducing our
ability to locate it.
Ans: True
The first place in the auditory pathway where inputs from the two ears
converge is:
Ans: Medial superior olive
Only excitatory inputs to the two lateral superior olives are needed to locate
sounds accurately using the differences in sound intensity coming to the two
ears.
Ans: False
The cone of confusion refers to the fact that many points in space can give
rise to identical ITD's and ILD's.

Ans: True
If the head is held stationary, there is no way to tell exactly where a sound is
coming from on the cone or line of confusion associated with that actual
sound location.
Ans: True
Changing the shape of your pinna has no adverse effect on your ability to
tell where a sound is coming from.

Changing spectral shapes across changes in elevation provide cues to
auditory localization.

Ans: True
The Directional Transfer Function is a set of measurements that take into
account the effect of body structures such as the head, ear canal, pinna and
torso on the intensity of sounds of varying frequencies reaching the ear.
Ans: True
Sound intensity varies in an inverse linear relationship with the distance the
sound source is away from the listener.
Ans: False
The "missing fundamental" is heard even though it is not physically present
because every harmonic of the fundamental has an energy peak at the same
time interval as the fundamental.
Ans: True
Timbre quality difference for two sounds is conveyed by low frequency
components that are not the same for each sound.
Ans: False
, 3 Exampromax - Stuvia US 2025/2026
A recording of a piano note played both forward and backward sounds
essentially the same to a human listener.
Ans: False
In a real auditory "scene" sounds coming from a number of different
sources:
Ans: Are summed together in a single complex sound wave
Auditory Stream Segregation divides the auditory world into separate
auditory objects using only the ability to locate sounds in space.
Ans: False

and used principles of auditory stream segregation in their music.
Ans: True
Timbre differences for different types of musical instruments (pianos,
trombones, saxaphones) allow them to be heard as separate auditory
streams when combined in the same time sequence.
Ans: True
Sounds are easier to identify as separate auditory streams if they are familiar
to the listener through prior exposure and learning.
Ans: True
The larynx of humans is positioned in the throat very much like that of
other animals.
Ans: False
One effect of increased testosterone in males during puberty is to increase
the mass of vocal folds.
Ans: True
