Section 1 Flashcards
Sound is?
A class of Physical kinetic energy called acoustic energy
Acoustical energy consists of
Fluctuating waves of pressure in a physical medium-usually air
1 cycle of 1 acoustical pressure wave consists of
1/2 compression(higher pressure)
1/2 rarefaction(lower pressure)
Higher amplitude=higher(louder)or lower sound(softer)
Higher
What is cps? What’s the cps range for sound
Cycles per second,20-20,000
What is frequency?what is the general correlation between frequency and pitch?
Rate of air pressure fluctuation,higher frequency=higher pitch
Cps is = to_______
1 cps=________
Hertz (hz)
1 hz
What is the period of the wave?how is a waves period expressed?
The amount of time required for a complete cycle of a sound wave.
In seconds per cycle
What’s the equation for the periods of a wave
Periods=1/frequency
