How do ear defenders work using a model of energy transfer?
Ear defenders do not transfer the sound waves, instead they absorb them, so as little sound as possible is transferred to the ears
How do ear defenders work using the big idea of energy transfer?
It absorbs sound waves by increasing air resistance reducing the loudness of the waves. The energy is transferred into heat and the person wearing them can hear sounds at a quieter amplitude than the actual sound.
What does the outer ear do to sound waves?
to funnel or pass sound waves through the ear to the middle ear
Which structures within the ear transfer a sound wave during hearing?
The ear drums are responsible from transferring sound waves from the outer ear to the middle ear. It vibrates in response to these waves.
What do ear protectors actually do to sound?
Ear protectors block out most or all sound waves trailing towards your ears, If sound waves are really hight your ear drums might pop/burst.
How do ear defenders work using a model of energy transfer?
Ear defenders do not transfer the sound waves, instead they absorb them, so as little sound as possible is transferred to the ears
Where do people wear ear defenders?
people wear ear defenders because incase of a high pitch sound the ears defenders absorb the sound and then you don't have an ear infection.

How do ear defenders protect your ears?
Ear defenders protect your ears by absorbing the sound and fizzling it out
What does the outer ear do to sound waves?
to funnel or pass sound waves through the ear to the middle ear
How ear defenders effect pitch and amplitude of sound?
I think because as the sound waves loose energy the frequency becomes less frequent so the pitch gets lower
How do you hear sound through the ear?
when you hear things, its really sound waves. the sound waves enter your ear, then it vibrates the ear drum.
How do ear defenders protect your ear?
Well, ear defenders absorbs the sound from going to your ear, if you don't wear ear defenders when your working in loud noises your ear can be damage.
When making ear defenders why do hey have a hard plastic outer case?
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. Rate This Answer
What of the ear collect sound waves?
The Pinna/Pinnae collects the sound waves.
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
What does the outer ear do to sound?
gather sound waves
