CMD 320 EXAM 3 Review -- Spring 2025

If the source is a complex aperiodic sound, that means that the vocal folds were:

If the source is a complex periodic sound, that means that the vocal folds were:

At the upper limits of hearing, high level sound perceptions can turn into _______ sensations.

Dynamic range is measured by subtracting the MAP threshold from the Threshold of Discomfort for a particular frequency.

The smallest perceptible difference between two sounds is called a:

Therefore, one could say that the entire auditory system is organized based on frequency processing and pitch perception

The core of the primary auditory cortex has ______ ______, just like the basilar membrane

Minimal audible pressure (MAP) curves are measured using:

About __ percent of auditory information is represented contralaterally

If a person has hearing loss, we would expect sound source localization and hearing-in-noise to be difficult for them

Outer hair cell motility and the SOC efferent pathway make it so that we can hear:

Uncomfortable loudness curves are relatively flat across frequency. That means that:

The primary auditory cortex is in the _______ temporal lobe, tucked within the ______ fissure.

If a sound source is at 0° azimuth, there are no ILDs or ITDs present

About __ percent of auditory information is represented ipsilaterally

The cochlear nuclei sit at the juncture of the ________ and ________

The head shadow effect results in interaural differences at frequencies:

When thinking about localization & auditory scene analysis, a sound source’s distance from the listener is unimportant.

The redundancy of the CANS enables some important auditory skills. One of these important auditory functions is:

The way someone perceives a physical sounds is based upon a number of cognitive variables. Some of these cog factors are

The redundancy of the CANS enables some important auditory skills. Another one of these important auditory functions is:

27

There is no physical sound energy outside of the range of human perception. We can hear all the sounds that exist.

Minimal audible level curves are not flat across frequency. That means that:

ITD and ILD cues are essential for _______ and _____ _____ _____

Covering a person's lips and articulators when they talk doesn't make speech perception any more difficult

Sound pressure level differences between the ears primarily occur at:

MAF thresholds are ~____ dB lower than MAP thresholds. This indicates ______.

A clinical test of the afferent Central Auditory Nervous System pathway is the:

Minimal audible field (MAF) curves are measured using:

The fundamental frequency of speech is directly related to the # of glottal cycles (or vocal fold vibrations) per second

What does ITD stand for?

When thinking about localization and auditory scene analysis (hearing in "3D"), azimuth refers to which plane?

Pitch perception is best at ____ frequencies and gets progressively worse as we move up the "scale" to ____ frequencies

What does ILD stand for?

If sound is coming into the right ear, most of it will be processed and represented in the _____ primary auditory cortex

"Interaural comparisons” in the CANS enable us to _______ sounds.

Vocal tract resonant frequencies are called "formants" in the speech sound output

The vocal tract acts like a quarter-wavelength resonator. The other structure in the body that resonates this way is:

The final sensory relay-station for auditory information between the brainstem and the cortex is the:

Outer hair cell motility and the CANS pathway enable “high-resolution hearing”

People with hearing loss have difficulty with their auditory perception. In particular, they often have deficits in:

Interaural timing differences occur at frequencies:

The ______ _____ is an essential location for cross-modal integration of the auditory and visual systems

The speech production mechanism is a combination of a “source” and a “filter”

ITD and ILD cues are primarily processed in the:

The following structure is NOT considered part of the auditory brainstem

The central auditory nervous system (CANS) consists of:

The first location where signals from both ears interact in the CANS is:

During phonation, vocal folds vibrate in a complex periodic manner, and therefore the sound they produce has:

The "waves" of an ABR are associated with "firing" electrical activity of locations along the CANS pathway

Efferent signals that control outer hair cell function are coming from the:

The CANS is extremely redundant, meaning:

The healthy human auditory system can perceive sounds from about:

The major resonating cavities of the vocal tract are:

Damage to the primary auditory cortex will likely impact sound awareness, but won't impact speech and music processing

Changing the fundamental frequency of the voice over time (prosody) inherently changes the formants of the speech sounds

This was my favorite class ever and I'm so sad it's summer. We had so much FUN!! :)

Speech contains only periodic sounds. There are no aperiodic sounds in speech.

Perceptual mapping involves relating signals in the _______ world to experiences in the _______ world

0° azimuth means that the sound source is:

CANS structures & functions are very well understood and are the primary functions we evaluate in clinical audiology

The McGurk Effect is an excellent demonstration of:
