NettetIn physics terms the difference between amplitude and intensity is that amplitude is the maximum absolute value of some quantity that varies while intensity is time-averaged … Nettet20. feb. 2024 · The intensity of a sound wave is also related to the pressure amplitude Δp I = (Δp)2 2ρvw, where ρ is the density of the medium in which the sound wave travels and vw is the speed of sound in the medium. Sound intensity level in units of decibels (dB) is β(dB) = 10log10( I I0), where I0 = 10 − 12W / m2 is the threshold intensity of hearing. korbin in the bibleNettet11. jan. 2024 · Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound. Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. korbin countryman

"NettetAs defined in physics, the intensity of a wave is proportional to the square of its amplitude ( A2 ∝ I ). So that means that if we want to emulate the effect of a sound being twice as far away, (1/4 the intensity), we would need to … " - Intensity and amplitude relationship
