Слайд 9How can you measure the level of noise?
The level of

noise is measured in decibels (dB).
The rocket engine is 140 dB
Girl’s scream is 127 dB
The sound of metro is 100 dB
«Hurrah!» is 100 dB
The harmful level of noise is 90 dB Clapping hands is 88 dB Vacuum cleaner is 70 dB Automobile traffic on the freeway is 60 dB Comfortable sound for a person is 30-40 dB The conversation is 40 dB The rustling of leaves is 10 dB The level of noise which is higher than 180 decibels can be fatal.

How can you measure the level of noise? The level of noise is measured in decibels (dB).The

Слайд 10 I made the experience

Слайд 11 Then I measured the level of noise in school № 19
The

results of measurements are: - in the cafeteria at dinner-time the level of noise was about 63dB; - during the breaks the level of noise was about 50 dB.
Comfortable sound for a person is 30-40 dB.
The harmful level of noise is 90 dB. The level of noise which is higher than 180 decibels can be fatal.

The conclusion is the level of noise in school № 19 does not exceed the comfortable noise level for a person. It means that the level of noise influences the health of our pupils and teachers not bad.
