Don’t Let Your Multifunctional Spaces Get Too Loud
Though we are living in times necessitating highly functional, flexible interior spaces, these areas can become annoyingly noisy and acoustically off putting, especially when involving home office situations and virtual conference calls. If you haven’t yet thought about improving the acoustics of your home, now is a good time.
Unwanted noise and unpleasant sounds are just the latest consequence of spending more time at home in open multi-functional spaces: more people at home at the same time; more time on video conference calls; more time learning virtually; more time consuming media; and more time pursuing hobbies & interests at home, such as playing musical instruments.
Equipped with the right knowledge about materials, products and approaches, you can significantly improve the sound in any room, without significantly extending your budget. Noise reducing treatments can help to create distraction-free and productive indoor environments, similar to how commercial office spaces are acoustically optimized.
Where to Begin?
The best first step is to set proper expectations. To clarify, this article is NOT about Soundproofing but rather Sound Absorption. This is the practice of reducing unwanted noise and sound levels within a room, by preventing sound from freely “bouncing around” within the given space by absorbing sound waves.
Soundproofing vs. Sound Absorption: What’s the Difference?
Soundproofing is a method of keeping sound waves contained in a physical space while stopping unwanted sound from entering that same space. Soundproofing product effectiveness is measured in STC’s or Sound Transmission Class. STC is the most commonly used measurement for sound reduction and is an indication of how much sound a wall, barrier or material might stop from penetrating. An STC rating of 60 or higher would be considered excellent soundproofing.
Soundproofing is more applicable for Sensory Rooms, Rehearsal Studios, Media/Theater Rooms and maybe Bedrooms, if you are a light sleeper. This would involve more extensive and costly construction and should be considered only when you have the luxury of starting from the studs to design and construct adequate soundproofing. In short, the details and methods are absolutely critical to create a truly soundproofed environment.
Sound Absorption on the other hand, actually absorbs sound waves that bounce around in space and distort acoustics, create background noise or produce an unwanted echo. Acoustic sound absorption is measured in NRC (Noise Reduction Coefficient) on a scale of 0 to 1. A higher value indicates more sound is being absorbed. Sound Absorption will not completely stop sound from entering another room, but improves the sound quality of an enclosed space. It will also improve how you sound on your virtual conference calls.

How to Mitigate Unwanted Sound
Understanding how acoustics work is extremely important in controlling noise resonance and determining the proper material to fix your sound issues. Do you need to reflect, absorb or transmit the sound waves to achieve your goals? What types of acoustic solutions are available?
The Basics of Room Acoustics
Mass is the key factor for controlling sound waves or abating noise. The thicker or denser the insulation material the better it will absorb sound. Insulation stops the transfer of heat, cold and sound by trapping temperature and sound waves into the insulating material. It is important to note that different materials have different densities and will perform better than others.
Hard surfaces such as walls, ceilings and floors reflect sound waves which create an echo. Therefore to eliminate this property, you will need to absorb the sound waves that bounce off these hard surfaces. This is achieved by increasing mass or insulating with a thicker, denser product for sound absorption. The two most important factors are noise reduction and absorption.
What is Wall Cladding?
Architectural wall cladding is the application of any material over another material to provide a layer for thermal insulation, sound reduction, weather resistance, or aesthetics. The material used for cladding can be comprised of any material including stone, wood, brick composites, polymers, polystyrene or various blends of fibers.
Can Wall Cladding Improve Sound Quality?
Architectural wall cladding, specifically acoustic panels, has characteristics which can be ideal for noise absorption to help improve privacy and security, while providing a unique design aesthetic. In many instances the “cladding” material is specifically engineered to have sound absorbing properties, however there are other materials such as stone and timber that insulate sound naturally.
Given that wall cladding is a popular interior design treatment, be sure to check the noise absorption properties of any paneling under consideration, as hard surfaces may worsen your situation.
External noise from traffic or neighboring homes can be reflected away from your home to give a quieter interior. Equally, sound waves can be absorbed within a room to insulate noise from travelling to other parts of the home. Depending on how acoustic panels are used, you can create privacy zones or acoustic separations within your home for:
- Home Office Spaces
- Home Theaters
- Music Listening Rooms
- Music Rehearsal Spaces
- Recording Studios
- Sensory Rooms
- Library/Study Spaces
- Virtual Learning Spaces
Products that Mitigate Unwanted Sound & Noise
When addressing specific noise issues, it is recommended to take practical, incremental approaches and measure progress along the way. An example of this approach is first making sure that a space is adequately “furnished” to counter the effects of hard surfaces (e.g. exposed hard flooring, drywall and tiles), with soft surfaces, such as carpeting, rugs, furniture and plants. This can be deemed the baseline before adding acoustic wall coverings and other acoustic treatments.
Here are types of products to consider that may be well-suited for your specific sound reduction needs:
- Acoustic Insulation
- Acoustic Panels
- Bass Traps
- Desktop Module Kits
- DIY Acoustic Panel Kits
- Movable Panels (AKA Gobos)
- Room Dividers
- Wall Cladding
- Wall Design Packs
Tools to Help Choose Acoustic Solutions
Given that acoustic panels are widely considered to be highly effective at improving the acoustics of interior rooms, most of these tools and resources have to do with selecting acoustic panels for a given space.
- Acoustic Art Panel Editors
- Free Acoustic Advice Forms
- Acoustical Room Calculators
- Room Acoustic Visualizers
Acoustic Art Panel Editors
Several leading manufacturers of acoustic panels offer the ability to create custom graphic prints. The process can entail some or all of these options: selecting orientation & dimension, thickness, insulation type, fabric, and spanning the graphic image across multiple panels (AKA multi-panel span or stack).
Free Acoustic Advice Forms
If you are addressing more complex noise issues, several leading acoustics-related websites have Free Advice Forms that will provide expert feedback and suggestions based on your unique situation and needs.
Acoustical Room Calculators
If you are leaning towards adding acoustic panels to a room, these two calculators will give you a quick overview of the likely number, size and cost of the panels adequate for a given room size.
Acoustimac has a quick and easy Acoustical Room Calculator to estimate the number of acoustic panels and sizes for rooms with ceilings of 13 feet or lower.
Audimute’s Acoustic Panel Room Calculator provides min and max panel recommendations across three treatment scenarios:
- Standard Treatment (e.g. offices)
- High-Intensity Treatments (e.g. recording studios and home theaters)
- Light Treatments (e.g. living rooms)
Room Acoustic Visualizers
GIK Acoustics has a free Room Acoustic Visualizer tool that allows you to create a 3D rendering of the space you are optimizing, with the ability to place GIK Acoustics products inside. If you plan to save or share your plans, you will need to create a free login account. The tool has several templates to start your design with, as well as several training videos to help you quickly get familiar with key features.
