Pitch

What is pitch defined as?

how sounds may be ordered on a musical scale

What type of pitch due high tones have?

high tones → high pitch

What does a pure tone’s pitch correspond to?

frequency

What does a periodic complex tone’s pitch correspond to? 

fundamental frequency (there are exceptions) 

Are all changes in pitch perceptible?

NO

What is DLF?

smallest pitch change you can detect

Can you detect an exact pitch?

-no, its impossible

-can say pitch is “lower” or “higher” 

What is perfect relative pitch? 

the ability to recognize and reproduce frequency ratios 

What is absolute pitch?

the ability to identify frequency of an isolated tone with high accuracy

What is the physical and psychological aspect of pitch?

physical: amplitude

psychological: loudness

What is affected when you reduce a sounds duration?

the sounds pitch

Can you perceive pitch of a 0.14 second sound? 

no

Can you perceive pitch of a 3-4 second sound?

yes 

What do you need long duration for?

very low pitches 

Can the intensity of a sound affect its perceived pitch?

yes

What does each color in this graph represent (intensity & pitch)?

green: not affected 1000-3000 Hz

red: tones above 3000 Hz intensity increases, pitch increases

blue: tones below 1000 Hz intensity increases, pitch decreases

Is pitch linear or non-linear?

non-linear

What scale is used for pitch? 

mel scale 

What is the minimum and maximum of the mel scale? 

20 - 20000 Hz 

What frequency corresponds to doubling pitch from 1000 to 2000 mels?

3,000 Hz

What is the pitch value if you double frequency from 1000 to 2000 Hz?

1,500 to 1,600 mels

What frequency corresponds to tripling pitch from 1000 to 3000 mels?

10,000 Hz 

Does same change in frequency equal same change in pitch?

no

What do low frequencies need to be so you can perceive them?

loud

What is phons?

unit of loudness level

What is mels?

scale/unit of pitch

What is sones?

unit of loudness

What does sones increase by, if phons increases by 10? 

phons increase by 10, sones increases by 2 sones 

What does the pinna do? 

enhances certain frequencies due to it being a resonant cavity
