Wood hoops don't decrease the amount of sound a drum makes. They change the frequencies and arguably add sustain. Though the type of wood and hoop would make a difference. Compared to say a die-cast rim, wood rims would make a substantial difference in the sound. Of course, it just depends what kind you want, sound that is.

Think: Triangles are made of metal.....not wood.
Cymbals are made of metal.... not wood
Metal hoops on a BASS DRUM are the best thing you can
do for shell resonance. I can't theorize what wood rims
do for snare drums.
Metal rims on BASS DRUMS are a great way to increase
resonance and sound....Make sure you don't have rubber
buffers between rim and BD claw. You want the sound
to be enhanced by all components...head, shell, rim, claws, etc.
Don't take my word. Call Mark Ross....he is a drum maker and
knows what it takes to build a real drum.
As opposed to a fake drum?
I'd have to disagree with this post. It's contrary to the entire 'Suspension' theory, and also blown away by the fact that metal is heavy, weight dampens the drum. That can be easily seen by trying different rims, die-cast being the heaviest vs aluminum rims which are the lightest metal rims out, there is a noticeable difference in sound and length of sustain. Heaviest -> Lightest.
Hardware, Rims, etc change the frequency of the overtones without a doubt. But metal does not cause a drum to have MORE sound. It's less sound, depending on the weight and player. A different sound. Metal, and different metals, resonate at different frequencies.
The most sound you can get out of a drum, is where the drum has the least amount of extraneous weight and shell material removed. IE, theoretically a drum with no rims or lugs would resonate the most - it has nothing restricting it's vibrations.
The proof is in acoustic guitars, the constant strive for more resonance, body and volume of sounds is constantly leading towards lighter construction (that weight thing again) and use of tone WOODS in body bracing.
And of course, high end drums that strive to reduce hardware weight and shell intrusion.
The common thing about wood rims is they soften the drum sound, which is fairly obvious considering you don't have (as much) material attached to the drum that vibrates at higher frequencies.
Metal rims weigh POUNDS. Pull your rims off some day and weigh them. Most the weight in a drum set comes from the hardware, a good 75% of it.
Adding metal to a drum sure as heck doesn't make it resonate more the weight difference alone is dampening the drum. It most definitely will change the pitch, frequencies and focus the sound - which if that's what you are looking for, rock on.
As an example, the PHX kit's have the new YESS system which uses a wood plate instead of a metal plate. Yamaha has tons of dollars into the R&D of these drums and they are by far superior sounding. In addition to using the lightweight aluminum rims, extremely low mass and single bolt lugs.
All of these changes are to remove as much weight and metal mass from the shell - and it works.
Besides, to use your own logic jean krupa, Marimba bars are made of WOOD... least the good ones that is. Piano's, Violins, Basses, Guitars, 95% of all acoustic instruments. The metal ones are made of brass, like cymbals, very few are made of steel.
BTW - No offense to Mr. Ross, but anyone using Keller shells ain't doing jack different from the 100's of other "custom" companies out there using them. Which while Keller is a great "base" for "custom" companies - they absolutely pale in comparison to shells built by companies using super high end woods and processes.
