When living in shared housing or apartments, noise can often become a serious issue. You’ll want your peace and quiet while your neighbor might have a different schedule, lifestyle or simply doesn’t share the same noise sensitivity. Soundproofing shared walls can be a practical solution to ensure your comfort. You’ll be glad to know there are various do-it-yourself methods to soundproof your walls effectively and cost-efficiently. Here’s an in-depth guide on DIY soundproofing for shared walls.
## Understanding Sound Transmission Class (STC)
Before embarking on your soundproofing journey, it’s essential to understand the concept of Sound Transmission Class (STC). This metric gauges a partition’s ability to reduce the transmission of airborne sounds such as voices, TV, or music. The higher the STC, the better the soundproofing. Residential walls typically have a rating of STC 30-34, but for true privacy, you’d want to aim for STC 50 or above.
## Material Choices
Some household items like bookshelves, thick curtains, or carpets can be reasonably effective for sound damping, but specialized materials designed for the purpose will work best.
### Soundproofing Drywall
This looks just like regular drywall but has increased density, incorporating materials like gypsum and steel, designed to absorb and nullify noise. While relatively costlier than normal drywall, it’s extremely effective, with a higher STC rating.
### Resilient Channel
This thin metal device can be screwed onto the existing wall, providing a base to mount your new drywall onto. By separating the two layers, it creates an air gap that helps block sound waves.
### Mass Loaded Vinyl (MLV)
This thin yet heavy material can be hung like wallpaper or attached to your wall using screws, nails, or adhesive. Because of its density, it’s effective at blocking out sound.
### Green Glue
This is a special kind of noise-proofing compound used between two layers of material, such as drywall. It converts sound energy into heat energy, effectively dampening noise.
## Implementing Your Soundproofing
### Adding Another Layer of Drywall
One of the simplest methods to soundproof shared walls is to add another layer of soundproofing drywall. This reduces the amount of noise entering your space. Use Green Glue to bond the two layers together, boosting noise reduction capacity.
### Installing a Resilient Channel
Install a resilient channel before attaching your new drywall layer for better results. The channel creates a soundproofing buffer, leading to more effective noise reduction. It’s critical to properly secure these channels to the old wall for a solid suspension.
### Using Mass Loaded Vinyl
MLV can be used either as a standalone solution or together with other methods for enhanced soundproofing. It can be attached directly to the wall or layered between drywall for better results. MLA is especially effective for low-frequency noise.
### Acoustic Foams
Though less effective than other methods, acoustic foams can be an aesthetically pleasing and easy-to-install solution. They help by absorbing the energy of the sound wave, reducing echoes and reverberations.
## Weatherstripping Tape
While primarily used to insulate gaps around windows and doors, thick, adhesive weatherstripping tape can also be beneficial for soundproofing walls. Stick it between drywall layers or other materials to create an extra soundproofing layer.
## Soundproof Wall Decorations
Hang thick rugs or tapestries on your shared walls to absorb noise. These won’t be as effective as specialized soundproofing materials, but they can make a noticeable difference in reducing echo and minor sounds.
## Final Thoughts
Effective soundproofing starts with understanding your goals and the type of noise you are dealing with. Then, selecting the right materials and methods becomes straightforward. Practice good noise etiquette and ensure the soundproofing you opt for satisfies your city’s building codes and the housing association rules. Also, always consider your neighbor’s comfort during installation – the aim should be to benefit all parties.
These DIY soundproofing methods for shared walls are a great starting point. However, professional consultation can be invaluable, especially if you are not accustomed to home improvements. The results promise not only peace but an increase in your property value in the long term.
