Sound
Sounds like bubbling water, rustling leaves are considered this type of noise.
white noise
We do not hear the squeaks of bats because their sound has a frequency that is this
ultra high
Harmonics are linked to this feature of a musical note
quality
Vibrating air columns are closely related to these instruments
Wind instruments
The pits of these discs are read at about 44,100 times per second.
CDs
Loudness, pitch, and quality are all characteristics of this.
musical tones
When you halve a sounds wavelength you do this to its frequency
double it
Singing in the shower is a likely place you will hear this phenomenon
Reverberation
Pianos make use of these vibrating against a sound board
strings
This type of laser light carries more information
Blue
Musical notes and periodic tones separate musical sounds from this
Noise
10-12 W/m2
threshold of hearing
Strings on an instrument that have lower frequency tend to have this
greater mass
Vibrating membranes are closely related to this instrument
Percussion
DVDs make use of this system
binary system
The pitch of a sound is most closely related to this
Frequency
This value is most closely related to the loudness of a sound
amplitude
The frequency of a note one octave lower in pitch than a 880-Hz note is
440-Hz
Frequencies needed to reproduce high-quality sounds
beyond the range of hearing
A single layer DVD has about this much more storage capacity than a CD
6 times
A decibel is a measure of a sounds
Loudness
Compared to a sound of 30 decibels, the intensity of a sound of 60 decibels is
1000 times as much
Wave superposition is an essential component of this
Fourier analysis
This is a partial tone whose frequency is a whole number multiple of the fundamental frequency
Harmonic
These read digital information represented by a series of pits on a disc
focused laser beams
