5.The energy of sound waves is always very small and can only be detected by our ears or other sensitive instruments
6.Which of the following is NOT a cause of vibration for musical instruments?
7.When an object is made to vibrate at its natural frequency of vibration, we say the object is
8.What causes a tuba to have lower sounds than a trumpet?
9.A violin is basically a hollow wooden box with strings across it.  If the wooden box were replaced by a solid piece of wood, the violin would sound
10.The organ pipe shown in the diagram produces a certain musical pitch.  Which of the other four organ pipes shown would produce the same pitch?
11.If a person blows over the top of the pipes shown in the diagram, which pipe will make a lower sound?
12.Low pitch is
13.The pitch of sound depends on the
14.Treble notes are high on the musical scale.  The vibrations producing treble notes have
15.Humans can hear sound with wavelengths that range from half an inch and to 50 feet.  Bass notes are low on the musical scale and have
16.What part of the ear is used to collect and funnel sound down the ear canal?
17.If all the waves shown above are shown for equal lengths of time,
Which of the options has a larger amplitude than the original wave?
18.If all the waves shown above are shown for equal lengths of time,
Which of the options has a larger frequency than the original wave?
19.Which distance, labeled above, is equal to one wavelength
20.Hair cells in different parts of the cochlea respond to different frequencies
21.Sound waves hit the eardrum and cause it to vibrate
22.The vibrations continue through the ossicles in the middle ear and travel to the cochlea
23.Sound that is too loud can damage the tiny hair cells of the inner ear.
24.The hair cells turn the vibrations into electrical signals that are sent to the brain.
25.Being around loud sounds a lot will help your ears get used to it and protect your hearing.
26.The more time I spend around loud sound, the worse my hearing will be.
27.Hair cells in the cochlea can be fixed after being damaged by loud sounds.

29.What determines the natural frequency in each of the following instruments?
30.Consider how each of the following instruments amplify sound. What makes them loud?  For each instrument provide three things: 1. Is the mechanism resonance or sympathetic vibration, 2. What part of the instrument makes it loud, 3. Why do you think this?
