Ear defenderes reduce the amount of noise (sound power) that gets to your ears by producing a physical barrier that absorbs the noise and muffles it.
Ear defenders work by absorbing the sound that was headed to your ear. They absorb the sound waves by increasing air resistance this reduces the loudness of the waves. The energy is converted into heat and the person wearing them can hear sounds at quieter amplitude than the actual sound.
Ear defenders work by absorbing sound waves.they absorb sound waves and vibrating particles which head to your ear and the ear defender helps because air resistance then increases and reduces the loudness of the wave at a lower amplitude. The energy is then converted into heat and so when you wear them it allows you to hear sounds at a quieter amplitude. =)
