Low pitch -more power? Anyone.

[Elza]

In one of the Kaplan videos it has been stated that low pitches (low frequencies) are transmitted with greater power, thus more energy, more intensity, which completely confuses me as I think that E=hf and v=f*lambda, so low pitch -> large waves -> small frequency -> smaller Energy -> smaller Power -> smaller Intensity?

Could someone clarify this for me? Thank you!

If some dude walks in with a low pitched voice and a high pitched voice, which one is more powerful ?

I believe sound waves have don't behavior like EM waves due to the difference in propagation.
Not going to lie, I am not very proficient with that subject but was overtaken by curiosity;

Shows frequency has an inverse square relationship to power...
