10 Smart Ways to Soundproof Ceiling

It’s 3 AM, and you are dead asleep in your room when a sudden noise from the ceiling wakes you from your slumber. Is your neighbor playing loud music and partying like it’s the end of the world? Or maybe he is rearranging furniture and the noise can’t allow you to sleep.

Luckily, you don’t have to go through this frustration as there is a solution for it. There are numerous ways to soundproof your ceiling that won’t make you break a bank.

Even if you don’t consider yourself handy with tools, worry not since most solutions do not need any construction skills.

Soundproofing works by lessening the capability of noise to travel from one point to another, where it is achieved by absorption and reduction of sound.

If you are tired of your loud neighbors robbing your peace every night, continue reading to know various ways to regain your peace of mind.

But before that, let’s look at the types of noises you might be dealing with at your home.

Types of Noises

Soundproofing your ceiling reduces two types of noise; airborne noise and impact noise. Other forms of noise like flanking noises are sourced from the surrounding. These are solved by soundproofing the windows and walls.

Airborne Noise

Airborne noises are transferred through the air by sound waves. Controlling or reducing these noises is hard. They include cars honking, crying babies, music, and loud conversation. Airborne sounds travel via the space within the setup.

Impact Noise

When you drop a book or stomp your feet, the ensuing noise is known as impact noise. It travels through vibrations conducted straight via the drywall linked by joists from the floor above to your ceiling.

Dropping dishes and footsteps are some of the examples of impact noise.

Components of Soundproofing

Knowing the soundproofing elements is important for the successful completion of your project.

They include:

Decoupling

This is a process of disengaging or separating things. And since sound is a vibration of waves, the vibration needs a conductor or solid pathway to follow. In the case of a ceiling, the studs or joists act as the solid pathway.

When it comes to decoupling, you need to separate the framing in your ceiling to break down the noise pathways,  consequently decreasing the noise.

Absorption

The impact of this soundproofing element is the absorption or soaking in of the noise, leading to the decrease of ensuing sound.

For insulation, use an insulating material to fill the spaces in the joints. The insulating material will absorb the vibration.

You can use various insulating materials such as cellulose, fiberglass, recycled cotton, mineral wool, and open-cell foam.

The concept of insulation isn’t to only fill the ceiling or compress the materials but to also reduce the density.

Mass

This component is important when blocking sound. The idea here is to make the walls heavy since huge walls make it hard for airborne sound to pass. However, it’s not useful for impact sounds traveling via the structure.

Mass-loaded vinyl, drywall, cement board, and plywood are high mass materials.

Damping

It is done using damping compounds. Damping compounds are unique in their ability to transform sound into heat energy and stop it from spreading.

For effective results, combine the four basic elements. You can install each element after the other considering the opportunity and cost.

Types of Ceilings

Another important thing you should know is your type of ceiling. This will define everything involved in soundproofing, such as the technique, procedure, cost, and time.

The common types of ceilings include suspended and drywall ceilings.

Drywall Ceilings

This type of ceiling is board-designed gypsum coated in paper. It’s different from other panels like fiberboard, plywood, or hardboard due to its unique properties. It has noise isolating properties and is easier to remove. This means you can fix it on your own.

Drywall ceilings are ideal for soundproofing since they are affordable and easy to make changes.

Suspended/drop ceilings

Drop or suspended ceilings are well known for their aesthetic quality. They dangle from the structural ceiling and can be easily removed.

They are made in a way that they provide an in-built decoupling. Nevertheless, other features like the availability of ductwork, light fixtures, and mechanical units offer a pathway for noise. Therefore, insulation in a suspended ceiling may not be as effective as that in a drywall ceiling.

Effective Techniques for Soundproofing your Ceiling

There are numerous methods you can use to soundproof a ceiling. However, you’ll need to combine them in various setups for effective results.

We’ll start with the most effective methods to the least effective.

1. Soundproofing the Floor Above

This entails building on the insulation matrix, a layer of damping/decoupling, and a double layer of drywall.

The first thing you should do is remove the drywall to expose the surface on the floor above you. Then, you remove the subflooring before applying a damping material on the layer of drywall.

Add a double layer of drywall with a layer of damping material in between the ceiling below and use the hat channels to decouple. You should then replace the sub-flooring.

This technique will guarantee a completely soundproof ceiling and less flanking sound.

2. Installing an Underlayment to the floor Above

Instead of doing the hard work of tearing down the ceiling to install different materials, you can make easy changes on the floor above.

Try convincing your neighbor if it isn’t your house. Bring down the existing floor to expose the subfloor below, and then install your underlayment and acoustic mat to eliminate the noise from the source.

Replace the existing floor and caulk the perimeter if you want. Though it may be costly, this is quite an effective process.

3. Mass Loaded Vinyl

This material can block sound effectively. It acts as a damping method and can be a good substitute for Green Glue. It’s composed of barium and vinyl sulfate.

Mass loaded vinyl is non-toxic and has a high relative density, making it ideal for blocking noises. It can be utilized as a carpet underlayment since it’s dense and tough.

In most cases, mass-loaded vinyl works best in blocking airborne sounds. You can place the material between drywalls or on the subflooring. It also offers extra padding to ceilings or floors.

Nevertheless, green glue tends to be cheaper and more effective.

4. Floating Ceiling Joists

This is a decoupling idea for lessening impact sound. This technique is most feasible for drywall ceilings, not drop ceilings, since the roof shouldn’t be filled with ductwork.

The process involves installing a new joist between the existing ceiling joists. Then, extend the new joists two inches below the original joists.

After that, install the insulation substance in between the joists. Don’t compress or over-pack the material to avoid affecting the freshly fixed joists.

The entire setup is effective in blocking airborne and impact noise.

5. Decoupled Ceilings

This alternative comprises of an insulated ceiling with a double layer of drywall and a layer of green glue.

Decoupling is included as a hat channel and resilient sound clips.

Start by removing the drywall from the current ceiling. You don’t fix the hat channels directly to the joists since that might prevent them from functioning properly.

Separate the hat channels from the drywall and joists using soundproofing clips. Then, fasten them with small screws, which should be 10 inches apart.

You will need to measure the joists to define the number of hat channels your ceiling might need. Then, divide the parts using a cutter such as a hacksaw.

Put the hat channels into the ceiling joists and make sure the small flange points to the roof and the large flange points downwards.

Attach the channels with the clips to prevent a transfer of vibration through the screws.

Start this procedure from one side of the ceiling and move forward. Once you come across a light fixture, lift the hat channels into place. Once you complete the decoupling process, attach the double layer drywall.

The matrix will isolate impact noise and is an effective soundproofing alternative.

The good thing with this technique is that it comprises all four components of soundproofing.

6. Double Layer of Drywall and Green Glue Damping

Damping material (green glue) application should be made according to the manufacturer’s guide on the drywall. Then add the second drywall over the original one and screw it to the base of your ceiling.

Seal the perimeter with acoustical caulk to finish the sealing procedure. If you aren’t happy with the results after this, add another layer of drywall for more mass and sound lessening.

The third layer of drywall will mean two layers of damping material. In this case, you should follow similar instructions as the double layer drywall and one layer of damping material above.

7. Double Layer of Drywall

The double layer of drywall is denser and more effective in blocking airborne noise. The setting is fiberglass with two layers of drywall.

It will make the ceiling thicker, thus creating more mass than the normal drywall.

Additionally, thicker drywall will lessen impact sounds.

8. Soundproof Single-Layer of Drywall

One layer of drywall isn’t effective enough to block or reduce noise since the board is light making it easier for sound to pass through. So, sound travels from the drywall to the studs and then to the air hollow in your ceiling.

Adding soundproof to the drywall is a valuable and feasible option. Soundproof drywalls are thicker and tend to have good soundproof quality than the normal drywall. The only disadvantage is that they are expensive.

A panel of drywall costs $10, and a single board of soundproof drywall costs $40. The high prices make these soundproof drywalls unpopular.

To soundproof or improve a regular drywall ceiling, fill the ceiling cavity with an ideal sound-absorbent or insulating substance like fiberglass.

In some cases, insulating substances such as open-cell cellulose can be used on drywall. However, you need the help of an expert to use the material. Its best used when unpacked or uncompressed.

This technique is effective in reducing airborne sounds but not impact noises.

9. Pin Blankets to the Ceiling

If you reside in a rented apartment, you may be restricted in numerous ways. You can’t make any adjustments to the ceiling or carry out a complex soundproofing project. Due to these challenges, pinning blankets to the ceiling is the best method to reduce sound in your home.

For better results, pin thick blankets. If you own the room above, add a thick rug on the floor to absorb the sound impact from that room.

Use nails to attach the blankest on your ceiling. While at it, avoid using thin nails since the blankets can slide off from your ceiling. Use nails that have fat heads to help in securing the blankets.

Keep in mind that while most blankets can be utilized in soundproofing the ceiling, not all will offer a good experience. Thicker blankets block airborne noises and vibrations. Also, look for blankets made of mineral wool, multilayered polyester or cotton.

Moving blankets are also quite effective in soundproofing the ceiling.

10. Install Acoustic foam Mats on Your Ceiling

These foam mats serve as insulators. They contain rubber foam and are petrol, water, and oil resistant.

They do not allow any noise or air to pass via them. Furthermore, they don’t absorb moisture or produce a smell as blankets do.

The foams are easy to attach to the wall since they are adhesive. They absorb all the sound that bounces off the ceiling and soften the echoes in your house.

Things to Consider When Selecting Soundproofing Methods for the Ceiling

The soundproofing materials for the ceiling range from soundproofing glue, curtains, anti-vibration pads, blankets, and rags.

Here are the things to consider when choosing the best method to soundproof your ceiling.

Type of Sounds to Soundproof

Normal sounds and vibration require various soundproofing methods. Some materials will work perfectly with vibration sounds, while other methods won’t work at all. So, it’s important to know the type of noise you want to eliminate.

Noise Level

Is it a high or low-frequency sound? Various levels of sounds require different methods for your efforts to be effective. The noise level will define the budget and material requirements of your project.

Budget

Choose materials that fit your budget. When looking at the cost of these materials, consider the long-term expenses. Don’t only look at the current price but consider the maintenance cost of the method, if any.

Performance of the Material

Heavy blankets and rags perform better than lighter ones. Pick soundproofing materials that can reduce almost all the sounds.

Tips and Precautions for Soundproofing the Ceiling

Ductwork can act as a pathway for sound between floors, particularly in suspending ceilings. So, substitute the inelastic duct with flex ducts or install cheap duct liners and deliver a curved pathway.

Ensure you adhere to the building codes and utilize the ideal screw to mount drywall to the pathway.

Remember that the STC values are important as they offer an estimated value of the soundproofing effectiveness. Nevertheless, the rating doesn’t take into account the very low or high frequencies.

Make sure you seek professional assistance and advice during the entire process.

Also, consider the budget. Many soundproofing techniques are cheap, but they can get ineffective; you’ll need to spend more. So, pay attention to your budget and what soundproofing techniques will work best for you.

Note that you can soundproof the current ceiling or break it down to make the required changes. Irrespective of the option that you think is comfortable and ideal for you, make sure you inform the owner of the apartment if you are a tenant.
