hearing Flashcards
1
Q
what is sound wave propagation
A
involves the transmission of vibrations or disturbances through a medium, resulting in the spread of sound energy
2
Q
what are resonant cavities
A
lumps of air at the entrance of the cavity oscillate under the elastic forces exercised by the air inside the cavity
3
Q
what is the preferred resonance frequency
A
inversely proportional to the sq root of the volume
(large resonators = deeper sounds)
4
Q
what is reflected in the frequency spectra emitted by objects
A
physical properties of objects, such as size, mass, stiffness
5
Q
what is the result of time-freq analysis
A
- place code for frequency (tonotopy)
- A rate code for intensity
- A time code for temporal structure (including “fine structure”)
