"Diffraction: Why Bass Music is Easier to Hear

[student07]

Homework Statement

If you hear music in the distance, would you be more likely to hear the treble or the bass notes of the music? Using your knowledge of diffraction, explain your answer.

2. The attempt at a solution
So I found that the bass's waves are carried at a longer distance than the treble ones and can pass through doorways or small openings at a greater distance than that of the treble since their frequency is not affected a lot by diffraction. Thus, the wavelength of the bass carries a longer distance than that of the treble but is it only because of the frequency?

Since the only difference between bass and treble is frequency what else could it be?
