Do you mean the types,..like shells with re-rings vs thick non re-ring drums ?
I was under the impression that the hole is cut to reduce the resonance quicker and not change the frequency at all, (stop the ringing) and the vent hole was to allow air change inside a drum with two resonance heads. (stale air causes dryrot to wood)
I thought a vent hole was for kids to put crayons into drums with?
510,
What do you mean by .."speak" ??

Drums do not have airtight seals. The air is constantly being 'refreshed' with or without a vent hole. Nitrogen and oxygen atoms (to name a few) are quite small and move about the drum with ease. An atom compared to a Tom would be like the Tom compared to Earth ... close enough.
As far as the drums capability, yes the larger Di. is capable of lower tunning than the smaller Di. but at some point the frequency of both can be equaled by tension of the head, much like the frett board of a guitar starts over but at an octive higher. I can get my 8" roto to sound just like the 10" by tension and they are clearly different sizes. I can get my E and A strings to sound identical, exactly the same by where I pinch the frett board when both are in tune. I think the frequency of a drum is determined by it`s with only if the tensions are the same...No ?? ...and there is facts in what VM2K said because when I had the solid coated BD heads my BD vibrated the cymbals and the snare but when I changed it to the cut-out center hole, 5", it stopped vibrateing the cymbals and the snare is much less noteable. So escapeing air plays a role in volume of the note !! Maybe I`m not clear on what it is when refere to a drum speak !!
OddBall - I understand what you are saying above and I'm sorry that it probably is unclear in what I have written here about what the "Speak" from BDs is. It is something that when others here have mentioned it in evaluating their shallow BDs I got what they were saying, and I used an analogy about upright basses in a post above to try to give some insight into how I think of the word when folks use it to describe that type of response from an instrument. I think it is something we can hear easier in the lower frequency range and is not as preceptable in higher frequency ranges. I've only noticed folks using the term in regards to lower instruments. Sorry, I'm not sure I can describe it.

But the humidity inside will be absorbed and released into the wood and out of the wood again (dryrot)
Kieth Moon put water and goldfish in his drink holder floor tom !! They are tight.

Well in that case,...when my BD speaks,...I`ll throw it a milkbone !! :D

Moonie had an acrylic kit built to hold the fish. It was a custom clear plastic job. The video is up on YouTube for the curious. Horrible playing, but an interesting visual.
Typical wood kits do not seal airtight. Humidity is a measurement of how much water the atmosphere can hold at a given temperature and pressure. That has nothing to do with the air molecules moving about. If one believes that a single oxygen atom bonded with two very small and simple hydrogen atoms are too large to pass in and out of a headed drum, then I would suggest that individual has not fully grasped scale.
We are losing sight of the points here.
Let's not get caught up in this minutia.
