2. Beath High School - Int 1 Physics2 amplifier amplifier to frequency amplitude decibels (dB) emitted frequency a device which turns a small amplitude electrical signal into a larger amplitude signal a measure of the energy of the wave the units used to measure the loudness of a sound signals or energy sent out from the source the number of waves or vibrations in one second

3. Beath High School - Int 1 Physics3 hertz hertz to noise pollution laser loudspeaker microphone noise pollution the unit of frequency a concentrated source of light made up of only one colour changes electrical energy into sound energy changes sound energy into electrical energy unacceptable levels of unwanted sound

4. Beath High School - Int 1 Physics4 octave octave to speed pitch sonar sound level speed a sound which is twice the frequency of another is said to be one octave higher how high or low a sound is apparatus emitting high frequency sounds used by ships and fishermen to locate objects underwater how loud a sound or noise is how fast energy travels from one place to another

5. Beath High School - Int 1 Physics5 trace trace to vibration tuning fork ultrasound vacuum vibration line or wave seen on an oscilloscope (CRO) two pronged metal fork used to make a sound of a single frequency a sound of frequency greater than 20000 Hz, a sound above the range of human hearing an area of space where there are no particles of any type present rapid to-and- fro motion
