Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is
where, P is the power through an area A.
The SI unit for I is {W/m}^{2}.
Sound intensity levels are quoted in decibels (dB) much more often than sound intensities in watts per meter squared.
The sound intensity level β in decibels of a sound having an intensity I in watts per meter squared is defined to be
where I₀ = 10⁻¹² W/m²
80dB sound intensity is greater than 60dB sound intensity.
80dB sound intensity can be found in loud radio and classroom lecture whereas 60dB sound intensity is the normal conversation.
