How to Reduce Noise and Sound Through Walls: 5 Easy Hacks



Living in an apartment block or shared accommodation sometimes means dealing with unwanted noise from the walls. Whether it’s a neighbor’s TV, street traffic, or other distractions, finding effective ways to reduce noise is crucial for a peaceful environment. In this guide, we’ll explore five simple hacks to help you reclaim your peace of mind.

1. Assess your noise reduction goal.

Before diving into the solution, figure out whether you want to reduce incoming noise or block outgoing noise. If you’re bothered by outside noises, focus on ways to block or absorb noise from entering your space. For those looking to control room noise, focus on vibration dampening, sound path redirection, and changes to your floor arrangement.

2. Locate the shore leak.

Identifying the source of a shore leak is an important first step. Knock on walls to find weak points, listen for sound passage areas, and inspect your walls for gaps around cables and pipes. Thin walls and poor insulation are often the culprits. You can also use a decibel meter or feel the air coming out of your hand. The goal is to find and address these leaks effectively.

3. Seal with acoustic caulk.

Once you’ve discovered noise leaks, sealing them is the next step. Acoustic caulk, also known as noise proofing sealant, is specially designed to reduce noise and vibration. Using a flat paintbrush or your finger, apply the caulk starting at the top and working down. Common leak areas include wall outlets, baseboard cracks, window sills and door frames. Once dry, the caulking is discrete and can be painted for a seamless finish.

4. Install the acoustic foam panels.

When the source of the noise is difficult to pinpoint, and includes high-frequency sounds, consider using acoustic foam panels. These acoustic foam panels absorb sound and are effective in reducing echoes. Determine the origin of the noise and place the panel accordingly. You can mount them directly on the wall or use a frame to determine the placement. For low frequency noise, choose thicker foam panels to increase sound absorption capabilities.

5. Find alternative solutions.

If the above methods don’t completely solve your noise concerns, consider additional hacks:

a. Add an extra layer of drywall.

Adding an extra layer of drywall to a noisy wall can significantly reduce noise transmission. This method adds mass to the wall, reducing sound transmission. Particularly effective for light walls, this solution is DIY-friendly for those with intermediate carpentry skills.

b. Use sound tiles.

Acoustic tiles, like foam panels, act as a barrier against noise. This wall strip enhances the acoustic properties, creating a buffer between the noise source and your living space.

Mount them on the walls to experience better sound reduction.

c. Place a bookshelf near a noisy wall

A budget-friendly and practical solution involves placing a bookshelf between the noise-absorbing wall and your living space. The bookshelf’s mass and density make it an excellent barrier against vibration and sound transmission. Other heavy furniture, such as chairs and tables, can also contribute to noise reduction.

By combining these hacks, you can create a comprehensive strategy tailored to your specific noise challenges. Experiment with different methods to find the perfect combination that transforms your living space into a haven of peace. Remember, a quiet home leads to a more enjoyable and peaceful living experience for everyone.


In the pursuit of tranquility, it becomes necessary to master the art of noise reduction through walls. From spotting leaks to sealing with acoustic caulk and outfitting spaces with innovative solutions like acoustic foam panels, our guide unlocks the secrets to comfort. Whether opting for an extra layer of drywall or embracing the versatility of acoustic tiles, the possibilities are vast. With these simple hacks, reclaim your peace, and let your living space resonate with the soothing harmony of a noise-free sanctuary. Your journey to a calmer, happier home begins now.
