The pitch is the frequency of a note. |
|
|
What is loudness? |
Loudness is the amplitude of a note. |
|
|
What is quality of sound? |
The quality of a note is the relative number and strenght of overtones present. |
|
|
What is an overtone? |
Overtones are integer multiples of the fundamental frequency. The first overtone is 2f. 1f=420Hz |
|
|
What is a harmonic? |
Harmonics are intiger multiples of fundamental frequency. The first harmonic is at f. 1f=420Hz |
|
|
What is sound intensity? |
The intensity of sound is the rate of sound energy incident on 1 m2 at a right angle to the direction of motion of the sound. |
|
|
What is thr formula of sound intensity? |

|
What is resonance? |
Resonance is the transfer of energy between 2 bodies with the same natural frequency. |
|
|
What are some examples of resonance? |
Breaking a wine glass when you use the same frequency tone as the fundamental frequency of the glass. Same thing with collapsing a bridge. |

|
What is the formula of the frequency of a stretched string? |
|
|
|
