For give me if I spelled the name wrong but I'm close.

I was going to say the name too but I couldn't remember how to spell it either.

Helmholtz! Sheesh!

Here's a Wikipedia article on it: Helmholtz resonance - Wikipedia, the free encyclopedia

Note near the bottom it talks about reducing drag on aircraft bu 40% using acoustic liners based on the Helmholtz principle. This effect was something I was a bit concerned about when people talked about removing the resonators from intakes. I thought it might induce standing waves in the intake that would hurt its efficiency. I think that is why "drone" is probably NOT a good thing too.

Thanks Jack!

I was close but no cigar!!!!!!

Ah, you guys opened yourself up for that! I just couldn't resist! (At least no one called those things "mufflers")!

Same here, its just not easy to prove when people think that cutting it off will make the intake more streamline like the aftermarket CAIs.
