One question is bugging me since years. By definition, the energy of a wave is proportional to its frequency, the higher the frequency, the higher quantum of energy the wave is transporting, right? BUT, if your neighbor is listening to music for example, it is always the low frequencies you will hear, ie the basses that permeate the wall. So, why do walls absorb high frequencies better than low ones, although latter ones transport less energy?
