The best thing you can do is get sound treatment with an air gap between the treatment and the wall that faces your neighbor. The cheapest solution here would be to get a large room divider curtain rod and a really thick, sound deadening room divider curtain.
The best way to soundproof walls is to use a combination of products in a soundproof system. Adding mass and density, decoupling the existing structure from the new and increasing the sound absorption capability of the wall ensures the highest noise reduction.
Like others have said a faux wall will be best. Real sound proofing methods usually employ a double stud wall with an inch or 2 gap in between.
Walls: Adding soundproof material to walls will cost around $1 to $10 per square foot. You can also spend $40 per sheet of soundproof drywall. The total cost varies based on the size of the room and the thickness of the drywall sheets you need.
The best affordable way to soundproof your walls effectively is to use drywall and other materials like acoustic caulk to create an air-tight wall space. Installed over insulation and sealed in to form an extra layer in your walls, drywall forms a solid barrier for sound.
Soundproof paint is a specially formulated paint that contains sound-absorbing particles. Once it's applied to a surface, it creates a thin layer between the wall and whatever sound it's intended to absorb. That might sound like science fiction, but to the credit of the manufacturers, it does work how it's intended…
You can use MLV between drywall layers to significantly reduce noise. Make sure to use acoustic caulk to plug gaps, leaks and cracks around doors, switches and anywhere else noise might be seeping through.
All factors considered, most homeowners pay between £900 to £1,400 in total, depending on the chosen wall soundproofing solution. While the above wall soundproofing estimates will give homeowners a good idea of what they can expect to pay to soundproof a wall, the actual price will vary based on several factors.
The purpose of the rubber in the sound isolation clip is to break up the sound that transfers from the plasterboard to the steel stud and through to the other side. Typically, a wall or ceiling would be constructed by installing a stud frame, finished with plasterboard.
Party walls need high-mass materials, like acoustic plasterboard and Tecsound, to insulate against noise. These high mass panels can prevent sound from entering your home or leaving it. This means that your noisy neighbours no longer bother you, but also you won't be bothering them.
The most popular Noise Nuisance Recorder is the NNR-P-A1, which includes the following items: Class 1 Data Logging, Integrating Sound Level Meter. Class 1 Sound Level Calibrator.
Strategically placed furniture, wall insulation, noise reduction windows, shutters, rugs, soft furnishings and hedges will all contribute to blocking disruptive noise.
One of the best ways to soundproof a room is to increase the soft materials you have around, like blankets, rugs, and curtains. This is also a temporary way to soundproof that's perfect for renters or folks with a lower budget. "The heavier the blanket, the more effective it will block airborne noise," says Chung-Sao.
Alternative Solution: Mass Loaded Vinyl + 5/8" Drywall
Mass loaded vinyl is a great soundproofing material because it is super dense, versatile, and great at blocking sound. Best of all, it checks the “varying materials” box.
Summing Up. It is not necessary to soundproof an entire wall to obtain good soundproofing. Laying soundproofing material over 15 to 30 percent of a room is sufficient to block noise.
