What would you use to make an ear defender?
if i made ear defenders i would : Use foam because - it will absorb the sound Use rubber because - it has a lot of air bubbles in it. Sound takes a long time to travel through gases like air . Also some of the sound may reflect off the rubber. airpoo Vacuums, because sound travels best through air and there would be no air to travel through. And use cotton wool. : )
Are leather gloves a good insulator for electricity?
Better than nothing at all. Best is rubber gloves.
Why do electricians wear rubber types shoes when climbing electric poles?
Rubber is an insulator, so it prevents the flow of electricity. Electricians typically wear shoes with rubber soles so they don't get electricuted.
What material is the poorest conductor of electricity?
Rubber compound is one of the poorer conductors of electricity. That is why rubber tape is used in both high and low voltage splices.
How is electrisity stoped by rubber?
Any dry material that is an insulator is normally a poor conductor of electricity and that is the reason, if it is used in the right way, it can help to stop you from getting an electric shock. By itself rubber doesn't stop you from getting a shock or from being electrocuted. Just having some rubber in your pocket or having some rubber somewhere in the room with you will not stop you from killing yourself if you touch a high voltage wire. That is not a joke. Kids and adults have killed themselves because they did not really know what they were doing. Electric power is really dangerous and should never ever be played with.Dry rubber is normally a good insulator so wearing dry rubber gloves and dry rubber-soled shoes can help to protect you if you have to work with electric power but any experienced electrician will tell you this: Because electricity is so dangerous you must go to school to learn how to work safely with electricity - and pass the necessary exams - before you try to fix anything that plugs into receptacles or sockets in your home, in your school or anywhere else.

foam would be a good material to use for the inside of the ear defenders, as it will give more support, as well as being dense to conduct sound. Foam has particles with several small air particles, forming sound waves to absorb into it's surface.
What does an ear defender particle diagram look like?
You have your ear defenders. Then the sound waves hit the ear defenders and bounce off it.Other answerFirstly you draw the ear defender. Most likely sideways.Secondly, you can draw the materials you want to use in order and add what the particles look like in each material - close together, far apart etc.Hope I helped XD

Why is cotton wool good for making ear defenders?
Cotton wool is a very poor ear defender against sound. The best hearing protectors are the preformed foam plugs that one rolls between the fingers to compress, then inserts into the ear canal before they expand. Some are more effective than others, but a noise reduction rating (NRR) of 35 is about the most effective.
