Sound Wave - correct answer ✔✔energy transmitted through a medium from one location to
another by particle interaction, this it can be called a mechanical wave
How frequency is perceived - correct answer ✔✔through pitch
sound wave parts - correct answer ✔✔made of a) compressions and refractions and
b)increased and decreased air pressure
how we perceive amplitude - correct answer ✔✔loudness
the ratio we use to measure amplitude - correct answer ✔✔dB
Two identical sound waves that are exactly "180 degrees out-of-phase" will - correct answer
✔✔cancel
RT60 - correct answer ✔✔the amount of time for sound to "die away" (-60dB)
to get rid of or greatly reduce reflections in a room, we use - correct answer ✔✔absorption
the diffusion of sound - correct answer ✔✔scattering of sound in all directions
life cycle of sound - correct answer ✔✔direct, early reflections , reverb
