Pitch Perception
The frequency difference limen measures this
What is PITCH DISCRIMINATION THRESHOLD?
Whole integer multiples of the fundamental (F0)
What are HARMONICS?
The peripheral auditory system acts as this
What is A BANK OF AUDITORY FILTERS?
Intensity:Loudness :: Frequency:____
What is PITCH?
The first component of the hierarchy of auditory behavior: ____, Discrimination, Recognition, and Comprehension
What is DETECTION?
The frequency at which frequency difference threshold increases rapidly
What is ABOVE 4kHz?
Temporal resolution is the ability to separate one component of sound from another in _____.
What is TIME?
Each location on this structure responds to a limited range of frequencies
What is THE BASILAR MEMBRANE?
This non-linear measure of intensity uses ratio and logarithmic scale to present a wide range of pressure levels.
What is DB SPL?
When the signal is presented before the masker
What is BACKWARD MASKING?
The phase locking coding of low frequency AND high frequency tones
What is TIMING & PLACE (low) and PLACE ONLY (high)?
Frequency resolution, frequency selectivity, and auditory filter width all share this ability
What is THE ABILITY TO SEPERATE OUT ONE COMPONENT IN A COMPLEX SOUND?
The basilar membrane goes through this process / function to designate different tones to different locations (A&P)
What is TONOTOPIC MAPPING?
A good frequency resolution : Accurate distinction between pitches of sounds :: A ______ threshold : Accurate detection of low and high intensity sounds.
What is LOWER THRESHOLD?
In (a hypothetical) loudness growth function, a 75 dB SPL is 10 sone and 85 dB SPL is 20 sone, which confirms this fact about loudness in dB SPL
What is PERCEIVED LOUDNESS DOUBLING BY +10dB INCREASES?
The perception of pitch is affected by these two variables:
What is DURATION AND INTENSITY OF A SOUND?
The relationship between duration and absolute threshold in signals longer than 300ms.
What is NO RELATIONSHIP?
A speech sound has frequency components across 100-10,000 Hz. Add a bandpass filter with a passband of 300-2kHz. This is the frequency range that is let through:
What is 300 to 2kHz?
Peripheral Auditory System:Rain Gutter :: __________:each downspout only lets rain through from a limited section of the gutter
What is EACH LOCATION ON THE BASILAR MEMBRANE RESPONDS TO A LIMITED RANGE OF FREQUENCIES?
A 4k Hz tone at 20 dB SPL is 30 phon. This is equal in loudness as compared to a 1k Hz tone at ________. (Number and unit)
What is 30 dB SPL?
A concept when lower harmonics phase lock to the pure tone and higher tones phase lock to the envelope. You can still hear the F0.
What is the MISSING FUNDAMENTAL?
The quality of frequency resolution in a narrow filter (as compared to a broad filter)
What is BETTER RESOLUTION?
Three descriptors of filtering in hearing loss (size of filter; quality of resolution; quality of speech recognition)
What is WIDER FILTER, POORER FREQUENCY RESOLUTION, and WORSE SPEECH RECOGNITION?
Forward masking : ______ :: Backward masking : 25 ms
What is 200ms?
Three descriptors of filtering in younger aged people (size of filter; quality of resolution; quality of speech recognition)
What is NARROW FILTER, BETTER FREQUENCY RESOLUTION, and BETTER SPEECH RECOGNITION IN NOISE?
