    and affect his health?

    •Discuss this information with the classmates and with the parents;
    • Test the effects of loud music on my body;
    • Measure the level of noise in our school;

    What is noise?
    From the Internet and books, I learned that SOUND is something that you hear.

    NOISE is a collection of sounds of different intensity.

    Dahl’s dictionary says:
    «NOISE is sound of any kind, voices, affecting the ear, loud voices, screaming, knocking, everything that gets heard in the ears».

    The influence of noise on a person’s health
    Noises can be
    pleasant and unhealthy.

    Pleasant noises include:
    the sound of the sea, babbling stream, the rustle of leaves, the sound of rain, birds singing and the voice of dolphins.

    We like to listen to these sounds. They help us to relax.

    The influence of noise on a person’s health
    But noise, loud music may influence the human body badly. Noise effects
    your ears;
    your nervous system;
    your heart;
    immune system.

    Loud music
    makes you irritable, nervous, weak, forgetful;

    you get tired very quickly;
    you can’t do your homework well.

    The influence of loud music on a person’s health
    A lot of children listen to loud music for a long time with the headphones. The maximum volume of modern player varies from 100 to 115 decibels.

    Scientists claim that if you use the music player for more than 90 minutes a day, you may lose hearing.

    9 слайд

    How 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.

    11 слайд



    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.
