Characteristics of Sound
Wavelength determines the _____ of a sound
pitch
The part of the ear that is visible from outside is called the _____ ear
The guy in the McGurk effect was wearing glasses, yes or no?
States that the reason we can perceive different pitches is because ____________
the vibrations of each pitch activate a different part of the basilar membrane of the cochlea
What is deafness?
Amplitude determines the ________ of sound
loudness
The outer ear channels soundwaves through the _____ to the eardrum
Auditory canal
According to evolutionary psychology, we most likely have hearing abilities in order to:
escape predators and increase our chances of survival
Why is place theory flawed?
Because the study showed that although specific parts of the basilar membrane vibrate for high frequencies, lower frequencies weren’t very localized/area-specific.
Are you more likely to go deaf from disease or from listening to music on full volume?
The latter
Loudness is measured by using ________
decibels
The cochlea is a part of the _____ ear (outer/inner)
inner
Losing hearing in one ear would make it harder to:
locate the source of a sound
The volley principle states that we can perceive pitches over 1000hz because neural impulses fire at a rate that is ____
slightly out of phase
Sensorineural hearing loss is deafness caused by damage to the _______
cochlea’s hair cell receptors
In a graph of a sound wave, the wavelength is the _______
period/frequency/distance
The three bones in the middle ear are called the ___, ___, and ___
hammer, anvil, stirrup
We can tell whether a sound is coming from our left or right because we can perceive _____
intensity
Why is frequency theory flawed?
Because it suggests that we perceive pitch by detecting the frequency in which neurons fire, but it can't exceed 1000hz, which is a frequency that humans can actually hear
Conduction hearing loss is caused by damage to the mechanical system that conducts sound waves to the _____
cochlea
Longer waves in a soundwave have _____ frequency
lower
Hair cells are located in the ________
basilar membrane
Why are our ears most likely located on the sides of our face, instead of having one big ear in the front?
To be able to better perceive location and intensity
The McGurk effect happens when:
our visual and auditory perceptions blend
What's rarer, Sensorineural hearing loss or Conduction hearing loss?
Conduction hearing loss
