a vacuum is a space with no particles in it. Sound needs particles to travel through because it is just vibrations travelling through the air. Particles vibrate and hit each other and pass the vibration on. But if there is no particles, the vibration cant travel so you cant hear anything- that's why astronauts need radios to communicate, space is a vacuum.
Sound travels better through solids because the particles are tightly packed together so the vibrations are passed on more quickly whereas in a gas the particles are spaced further away from each other and can travel around, so they don't hit each other as often, so the sound vibrations take more time to travel around.
So yeah i guess a vacuum is a good material for an ear defender :)
What else can I help you with?
How does the ear wax candle work to remove ear wax effectively?
The ear wax candle works by creating a vacuum that draws out ear wax when the candle is lit and placed in the ear. The heat from the candle melts the ear wax, which is then drawn up into the candle through the vacuum effect. This process can help to effectively remove excess ear wax from the ear canal.
What is the term for the flexible material that forms the material in the ear?
The term for the flexible material in the ear is called cartilage. It provides structure and support to the ear, helping it maintain its shape and flexibility.
How do ear defenders work using a model of energy transfer?
Ear defenders work by absorbing sound energy before it reaches the ear. The material of the ear defender converts the sound energy into small amounts of heat or mechanical vibration, thus reducing the intensity of the sound that reaches the ear. This process helps to protect the sensitive structures of the ear from damage due to exposure to high noise levels.
Why is plastic a good material to use for ear defenders?
Plastic (in conjunction with a couple of other materials) is a good choice for ear defenders for a number of reasons. First, it's tough and effective. It's also fairly cheap, readily available and easy to work with. Plastics come in a wide variety of types and with as wide a range of characteristics. Can anyone lookaround himself in a day and not see something made of plastic that is in use? Plastic is an excellent material from which to make ear defenders.
How does an ear wax candle work to remove ear wax effectively?
An ear wax candle works by creating a vacuum that draws out ear wax when the candle is lit and placed in the ear. The heat from the candle melts the ear wax, which is then drawn up into the candle as it burns. This process can help to remove excess ear wax effectively.
What is a good material to filling the ear defender?
foam and plistyreine
Is tinned foil a good ear defender?
no
Why is rubber a good ear defender?
It will expand to fit the ear to close all inputs
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 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
Witch is a better conductor a earing or a magnet?
ear rings a sit is made of material but in case of magnet it is a stone so ear ring is a good conductor.So be ware of wearing a ear ring ear rings a sit is made of material but in case of magnet it is a stone so ear ring is a good conductor.So be ware of wearing a ear ring
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!
Where can you buy ear vacuum equipment?
Ear vacuum equipment can be bought at most stores with a health and wellness section. Prices may vary by location.

What material gives your outer ear its shape?
Cartilage is the material that gives your outer ear its shape. This flexible and firm tissue provides structure and support to the ear, allowing it to maintain its form.
