How To Soundproof A Drop Ceiling
Drop ceilings combine form and function like few other alternatives. They allow us to set any ceiling height we like, they are easily customizable, and they allow for easy access when we need to make overhead repairs. There’s a lot to love.
Whether we want to create cozier spaces, increase heating and cooling efficiency, or hide overhead infrastructure, they serve on multiple levels. If you want to add noise control to that list, consider installing a soundproof drop ceiling. There are great reasons to do so.
Mechanical, electrical, and plumbing (MEP) systems create a lot of low level sound as they operate. This translates to overhead noise that increases the ambient volume of the room. Not only does this interrupt our quiet space, but it makes it more difficult to communicate with friends or family. We often get louder to compensate. That creates even more noise. The solution may be a simple soundproof drop ceiling.
What is a Soundproof Drop Ceiling?
If you’ve got some familiarity with drop ceilings, you may know that they aren’t inherently great at blocking sound. In fact, a standard drop ceiling performs far worse than the alternatives in the world of sound control. It all comes down to their construction.
A drop ceiling, or suspended ceiling, is simply a set of tiles laid into a T-grid system of intersecting supports that’s suspended from the true ceiling overhead. It allows us to hide MEP systems, but doesn’t do a world of good for the acoustics in the room.
When we soundproof any surface, we’re looking to add mass and density. Standard drop ceiling tiles have neither. Not only that, but if they aren’t well fitted, you’ll get sound passage around the edges. Luckily, there are ways to significantly improve the performance of drop ceilings. Why go to the trouble? Good question.
Why you want a Soundproof Drop Ceiling
So many of us have lived with excess noise for so long that we forget just how beneficial quiet spaces are in our lives. We just deal with it the way we always have. Unfortunately, there are a handful of negative consequences associated with chronic exposure to noise.
Noise increases stress levels
Stress is no good. We all do our best to avoid it every day. The fact that noise has been shown to raise stress levels is troublesome on a number of fronts. First, stress can lead to all kinds of health problems. Creating more quiet spaces in your life can actually improve your health and help you live longer.
Noise causes trouble concentrating
Noise exposure can also make it harder to concentrate. If you’ve got excess noise in the workplace, this can spell disaster. By reducing the volume of the ambient room tone, you’ll be less likely to make mistakes or miss deadlines.
Noise impacts sleep
Getting good sleep is an important part of maintaining a healthy life balance. When we deal with excess noise while trying to sleep, we don’t get the quality sleep we need. A soundproof drop ceiling can help ensure we fall asleep fast and aren’t disrupted by bumps in the night.
Noise can damage hearing
The louder the noise we’re exposed to, the more likely we are to develop hearing problems down the line. This makes it harder to hear our friends and family, and can also lead to a number of health issues.
As people’s ability to hear declines, they often develop tinnitus or a chronic ringing in the ears. Not only does this further diminish our ability to hear, but it’s another factor that can disrupt our sleep patterns.
Hearing loss has also been linked to an increased risk of developing dementia in old age. There is evidence to support the theory that an inability to hear can increase your chances of developing dementia. That’s a big risk that can be reduced by following a few soundproof drop ceiling steps.
Soundproof Drop Ceiling Basics
If you’re interested in creating a more soundproof drop ceiling for one of your favorite work or living spaces, you’ll need to understand a few basics first. They’ll allow you to address the type of sounds you’re plagued with in the most efficient way. Let’s look at the best way to soundproof a drop ceiling.
Identify the main source of unwanted noise
When it comes to suspended ceiling soundproofing, the first thing you’ll want to do is identify where most of your acoustical issues stem from. Footfalls from your upstairs neighbors will require a slightly different treatment than tackling noise created within the room. There are two main types of noise that need to be dealt with.
Airborne noise
Airborne noise is all around us. This is the type of noise caused by conversation, keyboards clicking, and any other sound that travels through the air into our ears. The main method of tackling this type of noise is to absorb it. This reduces reflections off hard surfaces, and that reduces reverberation. Introducing soft, absorbent materials into the space will keep the space quieter.
Impact noise
On the other side of the coin, we have impact noise. This is the type caused by people walking overhead, the neighbor blasting music, and any other sound energy that passes through surfaces and into our space. The go-to methods for reducing impact noise are added mass and density, as well as decoupling surfaces.
Both types of noise can be mitigated by a soundproof drop ceiling. Let’s look at how you can retrofit your current drop ceiling or design a new one with soundproof elements.
Improve the quality of your tiles
As I mentioned before, standard drop ceiling tiles do very little in the way of sound control. They are thin and light, and don’t absorb much sound energy. Replacing them with tiles designed to reduce noise passage will go a long way toward creating a quieter space.
There are a number of quality drop ceiling acoustic tiles on the market. So many, in fact, that you can easily find one that matches your needs and design aesthetic perfectly. They’ll seal you off from overhead noise and reduce reverberation from below at the same time.
For a more modern look, you can opt for microperforated panels. This type of panel is made of a harder material that’s perforated with thousands of tiny holes. You’ll barely see the holes, but they are enough to create a perfect balance of reflection and absorption (when used with the optional acoustic backing) that delivers a beautifully balanced sound. Plus, they can mimic all kinds of surfaces, meaning you can get what you want with the performance you expect.
If you don’t want to replace the tiles you already have, you can add an acoustic backing to improve their performance. Soundproofing drop ceiling tiles works especially well if you’re dealing with a lot of noise from your MEP systems or sound that travels through the plenum, or the area between the drop ceiling and true ceiling.
In commercial buildings, the plenum is often open and connects all units for heating and cooling efficiency. Unfortunately, this design also allows noise to pass from one unit to the next. Absorbing sound waves with an acoustical backer before they reach the tiles will go a long way.
Install insulation
Insulating a drop ceiling delivers solid benefits too. If you’re installing in a commercial space with a common plenum, this step is especially important. Any vibrations that make it into that empty void can make it into your space if given the chance.
Using sound insulation on drop ceilings will trap any sound waves before they reach your room. You can use standard fiberglass insulation, but you’ll get the best results with an acoustical insulation. Insulation for a drop ceiling will keep upstairs sounds up, downstairs sounds down, and your neighbor’s noise next door.
Decouple the T-grid from the true ceiling
If you’re dealing with a lot of noise caused by upstairs neighbors, decoupling the T-grid may be a helpful solution. Decoupling refers to the process of breaking the direct pathways that vibrational energy uses to pass from one side of a structure to the other.
T-grids are somewhat decoupled by nature, but adding some clips could completely cut you off from upstairs noise. They’re affordable and easy to install, and this investment in a more soundproof suspended ceiling will benefit your health and happiness.
