Possible objections:
1. "Sound" may refer to perception rather than to mere vibrations or waves in a medium.
2. If you're not present, how do you even know the vibrations happen?
3. How do you know reality is based on "natural principles"? Isn't that an assumption?
4. What if consciousness is required for reality?
How do you know that is not the case?
How do you know that things exist apart from the observer?
Possible objections:
If a tree falls in the woods and there is nobody there to hear it fall, does it still make a sound?
The answer is yes, because sound is defined as vibration and waves, which will still form in the local air, regardless, since the physical systems are sufficient to create the effect. As long as there is air and motion there will be a vibration and the transmission of sound; make a noise. Reality exists based on natural principles, even if we are not conscious of it.

4. What if consciousness is required for reality?
If you answer the above question, no, since there is no observer to hear, you would assume reality needs the filters of the human mind to exist, and reality would not continue to exist apart from the human mind.
How do you know that is not the case?
Reality is that which exists apart from the observer.
