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.
How does foam in ear defenders protect the ear from being damaged by loud noises?
It's a 'high density' foam, which moulds itself to the ear canal. The density of the foam, coupled with the snug fit in the ear, limits the volume of sound reaching the eardrum.
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.
What are the different types of ear plugs?
There are foam ear plugs, silicone ear plugs, wax ear plugs, and custom-molded ear plugs. Foam ear plugs are disposable and provide good noise reduction. Silicone ear plugs are reusable and moldable to fit your ear canal. Wax ear plugs are soft and comfortable, but not as effective for blocking out noise. Custom-molded ear plugs are made by an audiologist to fit your ear perfectly and provide the highest level of comfort and noise reduction.
What material can you use for ear defenders?

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.
Do the ear buds come with extra foam covers?
No, the ear buds do not require foam covers, so they aren't included. You can find some on the internet that are very inexpensive, though.
Where can one purchase foam ear plugs?
Foam ear-plugs can be purchased from many locations such as local drugstores, and stores like Walgreens, Walmart, Target, Sears, Overstock, Amazon and many others.
