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.
A good electrical insulator?
Two good Insulators are foam and styrafoam
Is tinned foil a good ear defender?
no
What is a good material to filling the ear defender?
foam and plistyreine
Why do headphones need rubber?
it feels good it your ear, it might have something to do with the sound
Why are foam rubber and cotton good to make ear deffenders?
It's soft enough to go into the ear canal, and fluffy enough to trap sound well.
Why is foam a good ear defender?
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 material can you use for ear defenders?
Foam, rubber, and cotton wool can be used for ear defenders.
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

Is the Land Rover Defender a good car?
amazing
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.
Why is cotton wool a good ear defender material?
Cotton wool is NOT good for hearing protection as it only has an average attenuation of 7dB whereas you require 25-30dB in an average metal workshop for proper protection. DO NOT use cotton wool as hearing protection EVER. If one tiny little cotton fibre gets left behind you're in trouble - ear infection on the way!
What material are ear plugs usually made from?
You should use foam because foam molds itself to the contours of your ears and or the inside of the defender therefore stops sound waves from entering. It also absorbs sound. If you increased the sound you would have to increase the thickness or density of the foam. Foam is used on car insulation as well for the same reason. It deadens vibrations.
