1. What would you expect to happen to the sound of a violin if you made the bridge much heavier? (This is done by clipping a ``mute" to the bridge of the violin.) Recall two features- how well would a heavier bridge do in transmitting the vibrations, and what would happen to the primary bridge resonance of one did this?
2. What would happen to the playing of a violin if one put soap instead of rosin on the bow?
3. At times in an auditorium, the speaker "howls" or whistles due to "feedback"? What do you think is happening?
4. What effect on the playing of a flute would the fact that it is made of gold or platinum rather than say plastic have?
5. Why is it more difficult to understand a woman or a child than a man? (Recall importance of the formants in making the vowel sounds, and examine how well the formants are mapped out by the harmonics of the various voices).
Why does amplifying a quiet speaker not make his/her voice very much clearer? See the note to the first part of this question).
