How To Block Out Low Frequency Noise

Because low-frequency sounds are hard to deal with, soundproofing projects targeted towards these sounds can be quite expensive. Fortunately, I have some affordable hacks that you can implement to reduce the impacts of low-frequency sound waves drastically.

1. Try Superchunk bass traps (corner bass traps)

Superchunk bass traps also known as corner bass traps (Click here for a guide on how to build one) are placed on the four corners of a room and extend from the floor to the ceiling. They use fluffy insulation and are highly efficient in blocking bass sounds.

Alternatively, if you don’t want to get your hands dirty building bass traps, you can purchase already made bass traps on Amazon.

These are easy to use and install. Actually, no installation is needed– you only need to place them at the corner of the walls. The one I recommend is the NEW LEVEL Charcoal Acoustic Foam Bass Trap. 

However, you should note that these bass dampeners are highly effective in blocking low-frequency sounds from leaking outside the room than leaking inside the room.

2. Try Acoustic Panels

Acoustic foam panels are highly effective in blowing bass noise and other low-frequency sound waves. They are great drywall alternatives and ideal if you don’t want to do major structural changes to your walls.

If you live in an apartment or a rented structure where your landlord doesn’t allow major structural changes to the unit, acoustic panels are the way to go.

If you’ve visited recording studios or night clubs, you’ve probably spotted acoustic panels. They are affordable and help reduce bass, reverb, echoes, and low freq sounds. However you should know that acoustic foams are not designed for bass absorption, so you should expect some slight difference is you use them.

3. Install Bass Blocking Curtains

Windows and doors are the biggest culprits when it comes to the noise problem. Windows have gaps and often are made of a single thin glass layer.

For this reason, windows are prone to leaking in not only low-frequency noise but also sound waves of different frequencies.

One of the efficient and effective ways to deal with bass noise coming through the window is by the use of noise dampening curtains. Even though these curtain dampeners are designed to reduce noises and echoes, they will also help in dealing with low-frequency sound waves and expect some noticeable difference after installation.

One of my recommended curtains is NICETOWN Blackout Curtains.

Not only will the curtains block unwanted noise, but they will also add aesthetic beauty to the room where you install them.

4. Create a sound barrier using drywall and green glue

Low frequencies sound such as bass can travel through the walls through vibrations. To deal with a noisy neighbor playing loud bass music, you can add a layer of drywall.

For effectiveness in reducing unwanted noise, it’s recommended that you add two layers of drywall and apply green glue in between. Here is a simple guide on how you can accomplish that.

Green glue will absorb all the vibrations and convert the sound energy into heat before traveling the sound waves reach the next layer of drywall.

5. Soundproof ceiling and the floor

To deal with noise problem to the maximum, do not forget the ceiling and the floor after you’ve sound dampened the walls, windows, and the door.

There are different DIY hacks you can implement to soundproof a ceiling. (Click here to see the article). This guide will also help you deal with footfalls, which can be quite a menace.

If you’re dealing with low-frequency sounds from the room upstairs, you can request those living upstairs to add some thick carpet. Thick carpets and rugs placed on the floor will help reduce foot stomps, and bass menace.

6. Seal all the gaps and cracks

Doors and windows often have gaps that leak outside noise in our rooms. In addition, over the years, ceilings, walls, and floors may develop cracks- which could also leak outside noise inside.

One of the ways to deal with these culprits is by sealing them for good.

You can use weather-stripping to seal the gaps on your door and windows. My recommended product is Kanzzy weatherstrip.

In addition, to seal cracks on the walls, ceiling, and floor, you can use green glue sealant. Remember its green glue sealant and not green glue compound- same manufacturer but different uses.

 Conclusions on how to block out low frequency noise

Implementing one or a combination of the above methods will significantly help in reducing low freq sound waves.

While you won’t see a 100% difference, you will notice some noise reduction from 40% up to 50%.

Recommended Articles

We have some articles that I would like to recommend to the readers.

Foundation Repair And Maintenance

We have described here the type of foundations, what is a foundation inspection and what should be included in a good foundation inspection checklist. We can discover problems in the foundation to make us ask ourselves if it is safe to live in a house with foundation problems, and what entails a foundation repair. Not only the repair activity itself but how it affects our wallets.

I explain if the foundation repair is actually covered by homeowners insurance and the actual foundation repair cost. We disaggregated these foundation repair costs and determined, the cost per pier when footings or piers are the solutions for the settlement of a foundation.

To repair a foundation, the service provider might require an underpinning system using piers: push piers vs helical piers where helical piers are preferable for residential real estate objects, despite their costs. Also when you compare helical piers with concrete footings, we can determine that helical piers are more cost-efficient than concrete footings, in my opinion.

We have water in the crawlspace, which can be an issue for the whole foundation if the problem persists, and an additional difficulty when selling a house with water in the crawl space, as it can provide the prospective buyer with a lot of bargaining power, so what can we do: I explain what to do when the crawlspace is flooded or there are simply puddles of water always standing, thus I describe how to remove quickly the water in the crawlspace and how to prevent the problem for the future. So I discuss if it is normal to have water in the crawlspace after a heavy rain, and the importance to perform a crawlspace waterproofing thereafter, normally by installing a vapor barrier.

I describe how to improve the air quality in the crawlspace and to accomplish this, I am reluctant to use lime powder in this article, where I explain the pros and cons, as I would be using lime powder only to avoid the dangers of raw sewage under the house.

We discuss the sill plate replacement cost and how to avoid the outdoor sump pump freezing because it happened to me once.

There are always new methods for repairing foundations. One of them that we investigate here is the Powerbrace foundation repair method.

Animals can be a problem when they live near the foundation: In the following articles, we describe how to remove them and how to prevent them from digging and burrowing. The articles are about animals digging holes around the foundation or when they are burrowing below concrete, below a concrete slab, or between gaps in concrete footings, for example.

In regards to basements, I describe how to solve the hydrostatic pressure in the basement, which is a lateral pressure that is the main cause for having a basement wall that is bowing, or that can be caving in or buckling. While a slight inward curve for basement wall bowing is acceptable, after that degree, you have to address the issue and face sometimes relatively high basement wall repair costs.

I provide to you some reasons why we will need a certified specialist to deal with a risky sewage backup in the basement because bacteria survive a long time in a contaminated sewage network, and also we discuss how to deal with a basement drain backing up in general and what to do when it happens only when flushing the toilet, something that is not a DYI project at all.

Concrete

I explain here the process of concrete lifting or concrete raising, which can be done through mudjacking or slabjacking. We recommend the latter, which injects polyurethane foam.

Framing

There are some interesting articles here, in this Framing category. I refer to sistering floor joists, as a methodology to reinforce existing floor joists with some emphasis on sistering 2x6 floor joists or sistering with 2x8 instead, and about the building code for sistering joists, for sistering rafters, and the code for notching floor joists.

Many of these problems have a consequence: sinking or sagging floors.

Water Heaters

About water heaters, we have a complete guide about water heater types and their installation requirements, about power vent water heaters, and venting in tankless devices, and I also explain in detail the difference between a mobile home water heater and a standard water heater. I also describe in detail how to remove the heating element without an element wrench using just a socket, and how to fix leaks.

We have a few reviews when a water heater falls into our hands, such as the Titan product portfolio, Navien lineup, the Titan N-160 reviews, the most praised by our readers, and the Rinnai R94LSi.

I study several water heater capacities and tested 20-gallon water heater units and a comparison between point of use and tankless water heaters.

We open a tankless water heater to show how does it look like inside a tankless water heater, and how to protect your water heater against the effects of hard water. I also explain the pros and cons of tankless water heaters because many people consider that tankless units are better than standard heaters and it is not always the case.

After the lifecycle of the water heater is over, I reveal to you different options to proceed with its disposal.

Electricals

Just because they became popular and related to current news, I study how to identify aluminum wiring and once discovered, how to proceed with its remediation or retrofit.

Pest Control

I have a featured article where I compare Orkin vs Terminix pest control services.
