Speech Science Exam 2 part 2
| Question | Answer |
|---|---|
| This is a partially or completely enclosed container with air inside that is set into vibration. | acoustic resonator |
| This is an object set into vibration, like a tuning fork. | mechanical resonator |
| This kind of resonator will resonate to a narrow range of frequencies. | undamped resonator |
| This kind of resonator will resonate to a broad range of frequencies. | damped resonator |
| This is another description for a damped resonator. | broad bandwidth |
| This is another description for an undamped resonator. | narrow bandwidth |
| This is the mid-point or peak of a filter. | Center frequency |
| This specifies a certain range of frequencies that will be allowed to pass through a filter. | band-pass or acoustic filter. |
| This blocks high-frequency components of the wave and allows low-frequency components to be passed through a filter. | low-pass. |
| This blocks low-frequency components of the wave and allows high-frequency components to be passed through a filter. | high-pass. |
| This is the right timing/frequency of force (as in a push) that results in the tendency of the system to respond at greater amplitude. | mechanical resonance |
| The frequency or set of frequencies at which an object vibrates most easily and with the greatest amplitude. | natural resonant frequencies |
| Occurs when an object or medium is allowed to vibrate freely after an initial disturbance. | free vibration |
| self-sustaining oscillation | The generation and maintenance of a periodic motion by a source of power that lacks any corresponding periodicity, as in vocal fold vibration that can be sustained as long as a certain amount of lung pressure is maintained. |
| acoustic resonance | The tendency of a certain frequency or frequencies to gain maximum amplitude that match the natural resonant frequency or frequencies of the object/resonator. |
| Occurs when an object is set into vibration by another object vibrating. | This is the definition forced vibration. In an acoustic stringed instrument, this occurs when the vibration of the string(s) set the air in the instrument into vibration. |
