Most people know that when a subwoofer is placed in a room that there is a small amount of sound that leaks through the walls and ceiling, causing vibrations. With this blog post, Hooke Audio will walk you through a few ways on how to reduce subwoofer vibration through walls. Let’s begin.
What’s Low-Frequency bass?
Music’s driving force is bass. It’s a combination of high-intensity, but low-frequency sound. The bass is created by the bass guitar, the bass key, and singers who have deep and coarse voices. It is important to understand what bass noise is before you can find the solution.
A subwoofer is essential if you love home theatre systems and enjoy music nights with your friends. However, it is important to learn how to keep the bass from reaching your neighbors.
How does Bass sound generate?
Owners of subwoofers often have questions about how to stop the bass frequencies from passing through walls. Mid-range speakers typically produce high-frequency sound. Subwoofers, on the other hand, generate deep bass with a physical manifestation and a strong sound impact.
Low-frequency bass sounds can be easier to feel, and they can engender a multitude of physical sensations. Deaf people can also feel them.
Bass has a long wavelength which allows it to travel through your entire apartment, floor, and walls. The problem isn’t the volume, it is the vibrations. It can cause vibrations to shake the walls and disturb your neighbors. It can be difficult to eliminate this structural noise due to the physical impact.
It is possible, but not impossible. Here are some life-saving tips on how to stop bass from traveling through walls of neighborhoods.
How to Reduce Subwoofer Vibration through Walls
People don’t often bother to find the root cause of problems before they seek solutions. People assume that having no technical or sound engineering background is the best way to solve their problems. They don’t find the right solution to reduce the vibrations of the walls and the bass noise.
As a responsible person, you don’t have to disrupt the peace of your neighbor for your enjoyment. Let’s talk about some simple tricks to reduce the sound frequency and bass noises that travel through walls.
1. Placement in the Near Field
Near-field placement is the best and easiest way to deal with vibration problems. This involves moving the subwoofer closer towards you. This will allow you to control the volume more effectively.
The volume can be turned down to reduce sub vibrations. This will reduce the chance of subwoofer vibrations reaching your neighbor’s homes.
You still get a loud sound but at a lower pitch. This will help you and your neighbors. You may also hear the bass sound being distorted around the room. The subwoofer, however, is what you get. You experience pure, heavenly waveforms that are a one-of-a-kind experience.
2. Subwoofer Isolation pads
There are many sub-isolation pads and stands available. You can also make your own.
They absorb and dampen the vibrations from audio devices. They prevent vibrations from reaching the floor, walls, and surfaces they are sitting on. By adding lower notes, the isolation pad improves sound quality and clarity.
3. Bass Traps
Bass problems can be caused by the dimensions of subwoofer placement rooms and areas. They tend to solve this problem by increasing the volume. This problem can be solved with acoustic treatment.
Acoustic bass traps are currently in high demand. These acoustic foam panels have many similarities to isolation pads. These traps can be placed in the corners of your living room and on the walls to absorb as much bass as possible.
They don’t deal directly with vibrations but instead handle sound waves that cause more vibrations by hitting walls. They are ideal for the absorption of stray bass sounds.
Bass traps reduce sound reflections, which can travel around and negatively affect your bass. They are unlikely to solve the noise problem. A bass trap is a great way to improve the sound quality. You won’t hear any weird sounds anymore.
4. Remove the Sub from The Floor
This is how you can make your sub float in the open air. To reduce or dampen mechanical vibrations caused by subwoofers, it is necessary to lift the subwoofer about an inch off of the floor.
It is important to avoid direct contact between subwoofers and the ground. This will reduce the vibrations that travel through the floor.
Decoupling, in simple terms, is about absorbing as many vibrations as possible and low-frequency noises as possible.
There are many subwoofer decouplers on the market. Subwoofer stands are available in a variety of materials, including rubbery material and metal decoupling pins. You can also make your own decoupler if you have the funds. Concrete tubing and cinder blocks are two examples.
While we can’t promise results, this alternative may help you get started.
5. For sub vibrations to be reduced, get Cinderblocks
A cinderblock is a clever tool that helps you to limit vibrations crossing your walls. Because they aren’t as deep and resonant as wood, they can be very useful in this situation. To create air gaps between your subwoofer and the vibrant material, you can set it on a cinderblock.
Many people find cinderblocks too boring to be able to use in their homes. If you don’t have many options, you can cover them with covers. You can cover them with attractive fabric covers and they will be set.
6. Concrete Tubing
If the above hack fails to impress, there is another. Your speaker can be placed on top of a concrete tube. It must be perfectly cut in length and filled completely with sand. Because it absorbs vibrations and adds weight, sand is crucial in this situation. These concrete tubes can be decorated or painted to make them more attractive.
7. Adjustments to the Bass Level
Most subwoofer owners don’t know how to adjust the bass levels. Most people don’t know how to adjust the sound system settings and technical stuff. Here’s a quick solution if that is the case. These settings can be managed with very little practice.
These settings are crucial for sound quality. You don’t need to make any major adjustments to achieve a three-dimensional musical experience.
Crossover. All information regarding crossover place settings can be found in the specifications of the speaker. The crossover can be turned up to the point that it starts rounding out the speaker’s music.
Gain. This part is the easiest and most important. Turn off the volume on the sub. Adjust it slowly until the subwoofer fills in the base.
Phase. Switch You can adjust the angle of the switch from 0 to 180 degrees to see the difference. It doesn’t matter what you are listening to, it just depends on how big the room is. Choose the one that makes you feel the most comfortable.
8. Adjust the Equalizer Frequency
Imagine hosting a party, and then realizing that your bass is not quite right. This is a problem that many people face. The bass can be affected by the room dimensions and device settings. This means that crappy vibrations maybe twice as annoying for neighbors.
Adjusting the frequency of your equalizer can help you solve this problem. This would improve the sound quality and decrease the frequency. This method might not be applicable to all speakers or subs. It will eliminate the raspiness to some extent.
All you need is a simple adjustment. Begin by turning down the 125hz slider of the equalizer until it is pleasant to the ears.
9. Green Glue – Try Something New
Although green glue is a common method of soundproofing, it’s not widely known. It is used to dampen low-end sounds and prevent them from moving between rigid walls.
It is a viscoelastic polymer. It is soft and absorbs all vibrations. It transforms the vibrations into heat later. This creates a sound space in your existing room. It is very easy to apply. The paste can be applied to drywall to soundproof your space. Green glue can be used with plywood to make your floor.
Resilient channels can be installed to make it soundproof. Make a new wall, and glue green glue between the existing drywall and your new one. This will create an air gap between the wall you are currently using and the one that is being added. It will trap the bass’s low-frequency sounds between the walls.
10. Major Construction
It would take a lot of work to make a house or room block bass vibration. To absorb as much vibration as possible, you would need to increase the mass of walls, ceilings, floors, and other surfaces.
I heard of someone who built a room within a room. This is how many people make their home theatre rooms. The room is built around the space where the theatre will be located and leaves an air gap between walls. To absorb vibrations, you’d fill the walls with acoustic insulation foam.
Other methods to reduce bass noise
These methods are great for blocking outside noise and bass. These are other ways to reduce vibrations from the wall and cabinets.
- White noise machines
- You can replace your down-firing subwoofers with front-firing ones. Down-firing subs produce higher vibrations.
- Soundproof your apartment using soundproof doors and windows.
- Resilient channels are installed.
