"Listen to the Sound" Sound PPT Courseware 2

A tuning fork is a sound-producing instrument

Purpose: debugging musical instruments and testing pitch

Structure (composed of 3 parts):

U-shaped metal fork with handle

Wooden box for amplifying volume

rubber hammer

There are letters and numbers on the tuning fork. The letters represent the pitch and the numbers represent the number of times the tuning fork vibrates per second.

Experiment

Compare the sounds produced by these two tuning forks. What are the differences? What are the different sounds when the same tuning fork is struck with different amounts of force? Use high, low, strong, weak to describe these sounds.

Experimental steps:

1. Use the iron nails on the side to hit the three hanging iron nails: large, medium and small;

2. Keep quiet during the experiment, listen carefully to the sounds made by different nails, and compare the differences;

3. Record your homework in a notebook;

4. Knock the big iron nail lightly and harder. Find the difference and record it in your workbook.

Consolidation exercises (judge right from wrong)

1. Strike two tuning forks of different sizes. The smaller one will make a louder sound.

2. If the same tuning fork is struck with different force, the pitch of the sound will change.

3. A tuning fork is a generating instrument used to debug musical instruments and test pitch.

4. Strike the same tuning fork with different forces. The sound produced when struck lightly is weak.

5. Among the three scales of "Duo", "�" and "Mi", "Duo" has the highest sound.
