blog busters sound

We learnt that: incetcs make a buzzing sound beacause their wings are beating very fast.Did you know that the harder you hit something the louder it is and the louder the noise and the longer it lasts the more dangerous it is for your ears.Also we can mesaure sound waves by counting the number of vibrations that occur per second.If somting is going slow makes a deeper sound and if something is going quikly then it will make a high pitched noise.

    Hi Mrs Waterland and class.

    That is a very interesting post. I never knew that the buzzing sound that comes from insects is their wings beating very fast.
