Chapter 1 &2 Flashcards
Two items that are not associated
Unrelated
Two items that are associated or affiliated.
Related or proportional
Two items that are associated such that when one item increases, the other increases
Directly related or directly proportional
Two items are associated such that when one item increases, the other decreases
Inversely related or inversely proportional
When two numbers with a reciprocal relationship are multiplied together, the result is one
Reciprocal relationship
Unit for length
Distance, cm, feet
Unit for area
Cm2, ft2
Units for volume
Cm3, ft3
Increase by factor means
Multiple by that number, increase by factor of 6 means six times larger.
Decrease by a factor means
Divide by that number
Decrease by a factor of three means
One third.
Do a number followed by the word have percent
No, percent is unit less
What kind of wave is sound wave
Longitudinal and mechanical wave
Can sound travel through a vacuum
No, sound must travel through a medium where molecules are alternately compressed and rarefied.
What is compression
Area’s of high pressure and density
What is rarefactions
Low pressure and density
Sound travels in a
Straight line
The effects of medium upon the sound wave
Acoustic propagation properties
The effects of the sound wave upon the biological tissue through which it passes
Biologic effects
Acoustic variables
Pressure, density and distance
What kind of wave is sound wave
Pressure wave
Acoustic waves
Longitudinal waves
Mechanical wave
Concentration of force in an area
Pressure
Unit for pressure
Pascals (Pa)
Unit for pressure
Pascals (Pa)
Concentration of mass in a volume
Density
Unit for density
Kg/cm3
Measure of particle motion
Distance
Measure of particle motion
Distance
Unit for distance
Cm, feet, mile
What describes the characteristics of a sound wave
Acoustic parameters
