We did three things and guessed what the sound would be like:ģ) the container, and bands, stuffed with a tea towel. This doesn’t happen in a room that has a sofa, carpet and curtains – the soft furnishings absorb the sound. Making it often sound louder (as we have lots of sound waves heading our way) and sometimes echo-y (depending on how large the room is and how long it takes for the sound to “come back to us”). Sound reflectionįor Science Sparks, we explored what happened to sound in different environments – have you ever been in a room with nothing in it? Does it sound echo-y? What is going on? What is acoustics?Ī smooth flat surface – such as brick, metal or wood, reflects sound – it makes it bounce and come back straight at us. An energy that is caused by something moving backwards and forward – like the vibration on a guitar’s string. Which, of course, have a fabulous Science element to them: Acoustics! What is sound, and how does it work? What is sound? ![]() Over on Red Ted Art, we have been making guitars. I usually blog at Red Ted Art and Life At The Zoo. Noise barriers alongside roads reduce the traffic sound for houses in the shadow zone. This makes it even more humbling to be here today with our simple sound experiment! Acoustic shadow zones are exploited by acoustical engineers to reduce noise. Everyone is doing it now, be it in Science Hangouts or just having fun with the kids at home. I think Science Sparks is doing AMAZING things in getting families and bloggers into science. Hello! Lovely to be visiting Science Sparks again. Maggy blogs at Red Ted Art and has a great sound science experiment to show us. Today, I am very excited and honoured to have the lovely Maggy Woodley guest posting for us.
