Quite the opposite really.

A drum riser will change the drum sound, acting as a resonator with the floor (fixed) or w/o it (floating).

Some like it, some don’t.

It takes some trial and error 2 get the resonance 2 work in ur favor so in most cases ppl choose resonant 4 stage (4 mobility) and floating/ dampened in the studio.

4 killing resonance, use un-even structures, different materials, and keep the joints a- symmetric.

Then stuff it with absorbers.

As 4 floating - I’ve seen many cool ideas: rubber bricks or tiles, tires, foam, shock absorbers etc.

The coolest idea were rigid buckets screwed 2 a 10mm plywood board.

YMMV,
