|
Term
|
Definition
energy
-resulting of pressure waves that are the product of force being applied to a sound source |
|
|
Term
| in order for sound to be created what is needed? |
|
Definition
1.vibration
-refers back and forth of motion of an object
2. vibrations must be applied to and create a disturbance in a medium.
-sound can occur in the medium as long as there is mass and elastic |
|
|
Term
|
Definition
| air molecules have the same characterics: they attempt to move back to their original positions aftertheyhae been displaced. |
|
|
Term
|
Definition
- the tendency of an object to remain i its current motion state
- opposite of elasticity |
|
|
Term
| how can sound be represented? |
|
Definition
| - waveforms, spectra, spectrograms |
|
|
Term
|
Definition
| - represent sound with amplitude on the vertical axis and time on the horizontal axis |
|
|
Term
|
Definition
| provide an excellent way to display speech sounds becasue they show frequency, intensity, and time. |
|
|
Term
|
Definition
| air molecules move parallel to the direction of the wave motion |
|
|
Term
|
Definition
| the motion of the melecules is perpedicular tothe direction of the wave motion |
|
|
Term
|
Definition
-sound that has all of its enegy at oe frequency, creating a pure tone.
- rare and ceated by tuning forks an pure tone audiometere |
|
|
Term
|
Definition
| - have energy at more that one frequency and include the sound created by the human voices, musical instruments, and the heater in the corner of the room. |
|
|
Term
|
Definition
- aka simple harmonic motion
-simplest kind of sound wave motion that can occur in a medium |
|
|
Term
|
Definition
iis the wave created after the sinusoidal motion
- helps simplify amplitude |
|
|
Term
|
Definition
| - maximum displacement of the particles in a medium |
|
|
Term
|
Definition
- the distance from the baseline to the point of max displacement on the wave
- determines the intensity of a sound and is related to the force with which the orginal particle disturbance was created. |
|
|
Term
|
Definition
- objective
- max displacement of particles is quantifiable and not open to different interpretation |
|
|
Term
|
Definition
- subjective
- involving the judgment and perception of the listener regarding the intensity of the sound |
|
|
Term
|
Definition
-Alexander Bell
- 1/10 of a bell
- unit of measure for intensity
- expresses the ratio between two sound pressures
- ratio is 1:100,000,000,000 |
|
|
Term
|
Definition
-compresses the very wide range of sound pressure that can be just be heard into a scale range from 140 to 0 dB
- decibel scale has no absolute zero |
|
|
Term
|
Definition
| difference between the greatest and the smallest intensities the ear can hear |
|
|
Term
|
Definition
-20 micro pascals (sound pressure)
- any pressure compared to the reference 20 micro pascals is expressed in dB Sound Pressure Level (SPL) |
|
|
Term
| SOUND PRESSURE LEVEL (SPL) |
|
Definition
- -reference in 20 micro Pascals
- negative value -5 dB Pascals |
|
|
Term
|
Definition
- HL
- # of decibels above an avg.
- hearing level of an audiometer i calibrated in dB HL |
