Exam 1 Part 10 Flashcards
Interplay of elastic restoring forces, stiffness of the material, inertia, and a quality of its mass
Vibration
What 2 properties must an object have to vibrate?
Mass (or inertia), elasticity
Property of a material that causes it to return to its original shape after being displaced
Elasticity
Strength of the forces within a material that resists the deformation in response to an applied force
Stiffness
Property of mass; body in motion tends to stay in motion
Inertia
Wave that has a repetitive pattern
Simple wave
Wave that does not have repetitive pattern
Complex wave
Wave that has repetitive pattern that you can predict
Periodic wave
Wave that does not have a repetitive pattern that can be predicted
Aperiodic wave
What type of wave do we produce?
Complex periodic wave
1st harmonic
Fundamental frequency (F0)
Includes amplification and frequency
Spectrum
Muscle that lowers the pitch
TA (vocalis)
Always want lung pressure to be _____ than atmospheric pressure
greater
Driving source of phonation
Positive subglottal pressure
When the string is approaching the point of equilibrium; the string ______ because of maximum inertia
Overshoots
At the greatest displacement the string experiences the elastic restoration and moves in which direction?
Back
Near equilibrium, what element is at its maximum to continue vibration?
Inertia
Maximal displacement, what element is at its maximum to continue vibration?
Elastic restoration
Time that takes to complete 1 cycle of vibration
Period/time period (T in seconds)
