Amplitude
Sounds are waves and waves have energy.
sound waves
Ear defenders don't reflect sound waves, they absorb or reduce the amplitude of the sound.
Sound waves move away from the source of energy, but other sorts of waves move perpendicular (at a right angle) to the energy source
no.

Sounds are waves and waves have energy.
Sound energy depends on waves.
That varies, depending on what causes the sound waves.
it depends how much energy is used making the sound the more energy the louder because sound waves are transverse waves and waves are a reapeating disturbance of energy
