12/10/21 Science - sound proofing a studio.

 Daffodils discussed how we might sound proof a studio, so that the neighbours were not disturbed by the loud noises of a rock band rehearsing. We thought about jobs where people have to use headphones or ear defenders to protect their hearing. Which materials are good at absorbing sound? 
The children drew a labelled plan for a sound proofed studio on the playground. They listened to each other's ideas for sound proofing:-
double glazing, padded doors, blinds, carpeted floors and walls, polystyrene roof tiles, layers, and thick trees surrounding the studio. These measures might help absorb sound or reduce the vibrations and volume.
In class we carried out an experiment to see which material would muffle sound best. Our options were polystyrene, newspaper, foil, wrap and a tea-towel. We wrapped a mobile telephone up inside the materials whilst it was playing music and then placed it into a model studio. 
We predicted which would be the best material for soundproofing and then carried out our test. 

Our results were surprising...  - ask your child to explain what we noticed.
