Sound Propagation
These type of waves describe the periodic variations in atmospheric pressure that arrive at the ear.
What is sound-pressure waves?
The graphic representation of sound waves.
What is a waveform.
The unit of measurement for frequency.
What is Hertz (Hz)?
The human ear acts as a
What is a transducer?
This term describes areas of greater than normal atmospheric pressure.
What is compression?
This property of a sound wave is associated with the intensity of the pressure variation.
What is amplitude.
The physical distance in a medium between the beginning and the end of a cycle.
What is wavelength?
The three main parts of the ear are
What is the inner, middle, and outer ear.
This term describes the parallel motion of sound waves.
ADSR
What is Attack, Decay, Sustain, and Release?
The unit of measurement for loudness.
What is a Decibel (dB)?
These hammer, anvil, and stirrup are also called this
What is the ossicles?
This term describes the are of lower than normal atmospheric pressure.
What is rarefaction?
Two pure tones that have equal amplitudes, frequency, and start their cyclic periods at the same time are
What is in-phase?
This part of the middle ear converts sound waves to mechanical vibrations.
What is the eardrum, or tympanic membrane?
The outward pressure motion that is the building block of sound.
What is wave propagation?
The formula for wavelength.
λ = V/f
A decrease in 3 dB will change the level of a signal by
What is half?
The range of human hearing.
