as we go up in mass we go down in resonance frequency
Sound pressure Level (dB SPL)
looks at what is received on a diaphragm
-measured in upa, 20upa smallest pressure required for a human with normal hearing to hear 1000Hz tone
changes upa to dB SPL
20 X log(p1/p2)
comparing two different pressure values
the study of the relationship between physical stimuli and psychological response
measures sound by pitch loudness and localization
describes how high or low a sound is perceived. In general is rises as Hz rises
subjective experience associated with sound pressure (amplitude)
equal loudness contours
in order for a sound to be perceived as louder you need to increase the intensity. In order for people to perceive different freq as the same established anchor or reference tone you need to increase the intensity. more for lower freq
the ability to determine where sound is coming from.
-our ears use intensity and phase differences to determine location.
