Membranophones are musical  instruments that make sound from the vibrations of stretched materials. Drums are a good example of a membranophone.

In this episode of Hub Lab we will...
1. Explore sound and harmonics.
2. Design and construct your own musical instrument.
3. Explore the different properties of materials.

Phil of Science is going to show you how to make your own instruments with bits and pieces you can get your hands on and with a bit of luck we will be making sweet music.



That's sound!

Sound is made up of vibrations. These are called sound waves and they are what we hear. These sound waves are formed by objects shaking back and forth. They travel through air, water, and solid objects as vibrations. When they reach our ears, these waves make our eardrums vibrate. This sends signals to the brain and it figures out what we're listening to.

Membranophones are musical instruments that make sound from the vibrations of stretched materials. Drums are a good example of a membranophone.

This experiment which was originally put together by Exploratium in San Francisco was brought to Ireland as part of the European Tinkering project. The idea of this project is that you build your own devices / inventions and then you keep messing with them in order to make new things.

For the membranophone Tinkering might mean changing the length of the straw, tube or even trying different materials entirely. Once you are producing vibrations you will be producing sound. Changing the types of materials or the length of things will change the shape of the vibrations produced and therefore change the sounds.

For instance, if you shorten the pipe, the higher the pitch of the sound. You should muck about with you constructions and see what new inventions you can come up with.
