Can you splice stair stringers?
You need a stair stringer of about 18′, so I would get a 2×12 of 10′ and 8′ and splice them together with a 4′ splice: 2′ on each side of the joint, using a 2×12 as the splice. Then you can cut out the stair stringer and splice together. Then screw or nail the splice together well.

Can you soundproof between floors?
Short of that, placing a dense sound barrier in the open joist spaces between the floors is the most effective way to slow the transmission of noise. This is done is by removing the ceiling drywall and inserting enough fiberglass or rockwool insulation to fill the joist space.
Can you soundproof an existing floor?
Existing floors can be soundproofed from below using insulation (like roxul/rockwool to address airborne noise between floor/ceiling), resilient channels and other noise isolating materials like Green Glue (to decouple ceiling from the floor joists, limiting impact vibration and noise from transferring.
What is the best flooring for noise reduction?
Here are some of the best acoustic flooring materials:
- Carpet. Carpet or carpet tiles are known for mitigating impact sound, making them a perfect choice for hotels, classrooms and offices.
- Cork Flooring.
- Wood Plastic Composite (WPC) Flooring.
- Rubber Flooring.
- Vinyl Tile.
