amplitude, frequency, and energy???

this question came up in our music appreciation class:
does it take more energy to increase the amplitude of a soundwave of a high frequency than it does a lower frequency wave?

Welcome to the PF, Stert. Questions like this from homework or coursework need to be posted in the Homework Help forums, like this Intro Physics homeowork forum where I've moved your post. We also require that you tell us what you know so far, in order to provide you with help.

So what can you tell me about the energy of a sound wave? At least in electronics, for purely resistive loads, the energy dissipated is independent of frequency and depends only on the load resistance and load voltage (peak-to-peak or RMS value). However, for reactive loads like when there are inductors and capacitors involved, the energy involved does change with frequency.

Do a little research with google or other resources, and tell us what you think the answer is and why.
