Question Soundproofing stairs

My basement stairs were boxed in with hideous faux wood panelling. I've finally got round to ripping it out and intend to leave the area beneath the stairs open for shelving, just covering the underside of the stairs with drywall. My only concern now is that the stairs are noisier underfoot.
Is there any way to deaden or at least reduce the thudding on the stairs?

Did you remove and replace the treads and risers? I just finished removing carpeted 2x12 treads from a project and the owner wanted oak treads and poplar painted risers. Talk about noise difference. From a quiet thud to a ringing twang, but that's what they wanted. I find that, not only for securing the treads down, but to help deaden the sound, a generous amount of PL400 adhesive under the treads will act as a somewhat of a cushion.
Exposed wood will ring, so without adding carpeting, I'm not sure how you will sneak up on anyone

If you have access to the underside of the stairs, consider applying a damping compound and drywall to the underside of the treads and risers. This will quite effectively damp the vibrations. Use 5/8" drywall, or perhaps 5/8" or thicker plywood. Screw into the stairs with screws that are not so long as to poke through the stairs.

Bud mentioned this product a few weeks ago. Sound Isolation | Home Soundproofing Walls | Active Noise Reduction Systems | Noise Control Products Green Glue Company

He says he hasn't used it, but someone he knows had and had good results from their application. I perused their website and they seem to have a bunch of good info about sound on there that is worth reading.

If you do use it, post back and let us know how well it worked.
