When sound is loud, _____________will be___________.

When sound is low pitched, _____________will be___________.

When sound is high pitched, _____________will be___________.

Be able to identify an oscilloscope picture of the 4 following waves:                              1.  loud high pitch    2. soft high pitch    3. loud low pitch   4. soft low pitch

Know this information learned in the 2 anchor texts for this unit, for the quiz on Friday.  It should be in your blue foldable and glued into your ISN.  If you lost your foldable, make sure these notes are in your ISN before Friday to help you on the quiz.

Anchor text #1

Sound is energy made by vibrations.

Sound waves keep going until they run out of energy.

Sound waves require a medium through which to travel.

Sound cannot travel through a vacuum or space.

Sound travels through solid 13 times faster than air.

Sound travels through a liquid 4 times faster than air.

Sound travels through mediums at different rates.

Sound travels faster through a solid and slower through air.

More volume = more amplitude

Amplitude = volume or intensity of a sound

Frequency (speed of wave)  = pitch

More frequency = higher pitch

Less frequency = lower pitch

Draw a wave and label all the parts. (crest, trough, resting point, wavelength, amplitude)

Anchor text #2

What is Auto-Tune and do you think it is right for artists to use it during concerts and recordings.  Why/why not?
