Term
| what is the result of vibration or disturbance in the air? |
|
Definition
|
|
Term
| what is the phase of sound in which the vibratory movements of an object increases the density of air molecules because the molecules are condensed/compressed? |
|
Definition
|
|
Term

Term
| what is the back and fourth movement of particles when the movement is symmetrical and periodic? |
|
Definition
|
|
Term
| what is a wave with horizontal and vertical symmetry, contains one peak and one valley and contains a single frequency as a result of simple harmonic motion? |
|
Definition
|
|
Term
| what is a wave that doesn't repeat itself at regular intervals? waves that do? |
|
Definition
irregular: aperiodic waves
regular: periodic waves |
|
|
Term
| what is the magnitude and direction of displacement (or strength/magnitude of a sound signal? |
|
Definition
|
|
Term
| what is the quality of sound that creates the sensation of loudness? |
|

|
Term
| what measures sound intensity? |
|
Definition
|
|
Term
| what is a pure tone? complex tone? |
|
Definition
pure: when a tone contains a single frequency
complex: two or more sounds of different frequencies are added |
|
|
Term

|
Definition
|
|
Term
| what is the difference between natural frequency, fundamental frequency and formant frequency? |
|
Definition
natural: frequency with which a sound normally vibrates
fundamental: lowest frequency of a periodic wave --- this is the first harmonic
formant: frequency region with concentrated acoustic energy |
|
|
Term
| what is the interval between two frequencies? |
|
Definition
|
|
Term

|
Definition
|
|
Term
| what is the to-and-fo movement of air molecules? |
|
Definition
|
|
Term
| difference between frequency and period |
|
Definition
frequency: cycles per second (Hz)
period: time needed for a cycle to complete |
|
|
Term
| T/F the medium that transmit a sound doesn't affect the frequency, but it does effect the speech of a sound |
|
Definition
|
|
Term
| how is sound transmission effected in a dense medium? |
|
Definition
| is slows the speed, where as a less dense medium will make it faster |
|
|
Term
| T/F: a more elastic the medium will transmit sound slower than a less elastic medium |
|
Definition
| False: more elastic means faster |
|
|
Term
| the normal ear of a young adult can respond to what range of Hz? |
|
Definition
|
|
Term
| The human ear is more sensitive to higher/lower frequencies |
|
Definition
|
|
Term
| what is the measure of magnitude of a sound signal? |
|
Definition
|
|
Term
| the higher the amplitude of a sound, the greater/lesser the perceived loudness of that sound |
|
Definition

|
Definition
| time between the release of the stop consonant and the beginning of the vowel |
