I believe I saw referenece to the sound of one hand clapping somewhere in the gemora of masechet berachos.
Can you please remind me which daf this might have been? Thank you.

I'm not sure I found what you were looking for, but here is an idea. The Gemara 59a explains that an earthquake is the result of Hash-m clapping one hand onto the other. The Gemara then mentions that the sound of an earthquake is a single rumble. Can this be what you were referring to?
