Question | Answer |
---|---|
Sound is this type of wave | Longitudinal Wave |
The number of waves per second | Frequency |
Symbol is f | frequency |
time for one wave | Period |
Length of one wave | Wavelength |
Symbol for length of a wave | Lambda |
Name we give to frequency of sound usually in music | Pitch |
Measured in decibels | loudness of sound |
The property of a wave that loudness depends upon | Amplitude |
A change in apparent pitch caused by the motion of the source or reciever | The doppler shift |
What actually is passing thru the air when we hear sound | Pressure Waves |
The product of a sound's frequency and wavelength | Velocity |
What actually causes most sounds | Vibrating objects |
The type of resonator with a pressure node at both ends | Open Tube Resonator |
The type of resonator which has a pressure anti-node at one end | Closed Tube Resonator |
The type of tube which resonates at 1/2, 1, 11/2, 2, wavelengths | Open Tube Resonator |
This type of tube resonates at 1/4, 3/4, 5/4 wavelength | Closed Tube Resonator |
The quality of a sound or the way a vibration actually sounds to a persons ear | Timbre |
Dissonance | An unpleasant sound |
Consonance | A pleasant sound |
The fundamental frequency | The lowest frequency which will resonate in a resonator |
Harmonic | Higher frequencies which will resonate in the same tube as the fundamental |
Open pipe (tube) resonator | A tube which is open at both ends |
Closed pipe (tube) resonator | A tube which has one closed end |
A loud then soft variation in the sounds amplitude caused by interference | Beat |
Octave | The difference in frequency between a fundamental and the first harmonic |
Overtones | The name given to the fundamental and all the harmonics |
