Sound

This time, we learned what is the different between listening and hearing, one is a  initiative to do, the other is a naturally occurring. also we know what is sound, ‘sound is created by physical vibrations that set molecules in motion, creating sound waves that travel through the air’. and we know different ages of people can  hear different sounds, the younger of human the most sensitive to sound normally.

we learned many knowledge about sound, but what i think interested is totally different with what we learn.

in the process of doing excise about imaging what is the figure, ground, field of a image, it is interesting that human imagination.

usually, we can know there are the sounds of burning fire, running maybe people screech.

but my classmate think that maybe have the police car whistle sound and sirens or brakes sounds of cars when they meet those people in the background of image.
