-
- Pupils should develop their knowledge and understanding of the
- properties, transmission and absorption of sound.
-
- Level 1 * know that sounds can be made in a variety of ways.
-
- Level 2 * know that sounds are heard when sound reaches the ear.
-
- * be able to explain how musical sounds are heard when sound
- reaches the ear.
-
- Level 3 * know that sounds are produced by vibrating objects and can
- travel through different materials.
-
- * be able to give a simple explanation of the way in which
- sound is generated and can pass through different materials.
-
- Level 4 * know that it takes time for sound to travel.
-
- Level 5 * understand that the frequency of a vibrating source affects
- the pitch of the sound it produces.
-
- * understand the relationship between the loudness of the
- sound and the amplitude of vibration of the source.
-
- Level 6 * know that when sound waves travel from one point to another
- they transfer energy through the medium.
-
- * be able to explain the working of the human ear and some
- common defects in hearing.
-
- * be able to describe the workings of audio devices, for
- example, the microphone, loudspeaker and telephone.
-
- Level 7 * know that sound waves can be converted into electrical
- oscillations, transmitted (as electrical, optical or radio
- signals) over long distances and converted into sound waves
- again.
-
- Level 8 * know that a vibrating object has a characteristic
- fundamental frequency of vibration, and that some systems
- produce resonant oscillations which can be advantageous and
- disadvantageous.
-
- Level 9 * understand the use of electronic sound technology, for
- example, in industrial, medical and social applications.
-
- Level 10 * be able to apply a knowledge of wave properties to explain
- common sound phenomena.
