Title: Intermediate 1 Physics


1
Intermediate 1 Physics
  • Sound and Music Glossary
  • amplifier to frequency
  • hertz to noise pollution
  • octave to speed
  • trace to vibration
  • voltage gain to volume

2
amplifier to frequency
a device which turns a small amplitude electrical
signal into a larger amplitude signal
  • amplifier

amplitude
a measure of the energy of the wave
decibels (dB)
the units used to measure the loudness of a sound
emitted
signals or energy sent out from the source
frequency
the number of waves or vibrations in one second
3
hertz to noise pollution
  • hertz

the unit of frequency
laser
a concentrated source of light made up of only
one colour
loudspeaker
changes electrical energy into sound energy
microphone
changes sound energy into electrical energy
noise pollution
unacceptable levels of unwanted sound
4
octave to speed
  • octave

a sound which is twice the frequency of another
is said to be one octave higher
pitch
how high or low a sound is
sonar
apparatus emitting high frequency sounds used by
ships and fishermen to locate objects underwater
sound level
how loud a sound or noise is
speed
how fast energy travels from one place to another
5
trace to vibration
  • trace

line or wave seen on an oscilloscope (CRO)
tuning fork
two pronged metal fork used to make a sound of a
single frequency
ultrasound
a sound of frequency greater than 20000 Hz, a
sound above the range of human hearing
vacuum
an area of space where there are no particles of
any type present
vibration
rapid to-and- fro motion
6
voltage gain to volume
  • voltage gain

how much bigger the output voltage of an
amplifier is than the input voltage voltage
gain output voltage/ input voltage
volume
how loud a sound is
