SOUND
Link Title
Fluctuation of pressure wave above and below atm pressure in a sinusoidal variation
Tangent Bulk Modulus
BT = V0 (dP/dV)
The frequency of a sound wave is associated with our perception of that sound’s pitch
4 characteristics to describe how we perceive sound
Pitch
related to the change in frequency
Loudness
the amplitude of sound
Tone Quality
the qualities of the waveform in pitch and frequency
Duration
BEATS
overlap of two waves that have different frequencies
SPEED OF
SOUND WAVE
Fastest on solid,slowest in air
SOUND INTENSITY
defined as the power carried by sound waves per unit area in a direction perpendicular to that area
FORMULA -
intensity of one sound can be compared to that of another of the same frequency by taking the ratio of their powers
graph of sound intensity-
graph in db-
RESONANCE
Speed of mechanical wave
