Introduction
Noise pollution is often overlooked in urban living, but its impact on daily life is huge. From the constant hum of traffic to the neighbour’s late-night TV, unwanted noise can disrupt sleep, reduce productivity and increase stress. In a city like Melbourne, where close quarters and busy streets are the norm, reducing noise pollution in your home is key to a peaceful living space. One of the best ways to do this is through insulation. Insulation keeps your home warm in winter and cool in summer but also plays a big role in noise transmission. In this blog, we will look at the types of noise, how it travels through your home and the best insulation materials and techniques for noise reduction.
Noise Transmission
Before we get into insulation solutions, let’s look at how noise travels through your home. There are three types of noise:
- Airborne Noise: This type of noise travels through the air and includes voices, music and traffic. It enters your home through windows, doors and gaps in the walls.
- Impact Noise is the noise produced by physical impacts, such as footsteps on a floor or objects being dropped. It travels through a building’s structure, making it harder to manage.
- Structure-borne Noise: This type of noise occurs when sound is transmitted directly through the building materials, such as the vibrations from a washing machine or plumbing. It often results in a deep, resonant sound that can be felt as much as heard.
Noise travels through walls, ceilings, and floors by vibrating the materials from which they are made. The denser and less flexible the material, the less it will vibrate, which is key to noise reduction. So, choosing the right insulation materials and techniques is important.
Insulation Materials and Their Noise Reduction Properties
Several insulation materials are good for noise reduction. Here are some of the most common:
- Fiberglass Insulation: Known for its cost effectiveness and versatility, fiberglass insulation is used in most homes in Melbourne. It’s good for both airborne and impact noise by trapping sound waves and reducing transmission. But not so good for structure-borne noise.
- Rockwool Insulation: Rockwool or mineral wool is made from natural stone and recycled materials. It has excellent sound absorption properties making it good for both airborne and impact noise. And its fire resistant properties add an extra layer of safety.
- Spray Foam Insulation: Spray foam expands to fill every nook and cranny creating an airtight seal. This makes it one of the best for soundproofing especially for airborne noise. It’s also good for irregular spaces.
- Cellulose Insulation: An eco-friendly option, cellulose insulation is made from recycled paper treated with fire retardants. It’s good for soundproofing, especially for airborne noise, and a great option for those looking for a sustainable solution.
- Mass-loaded Vinyl (MLV): MLV is a dense, flexible material that blocks sound. It’s often used in combination with other insulation materials for added noise reduction especially in walls and floors.
- Acoustic Panels: While not traditional insulation, acoustic panels are decorative elements that absorb sound, reducing echo and reverberation in a room. They’re great for home offices, media rooms or any space where sound clarity is important.
Insulation Techniques
To get the most out of these materials, you need to use them correctly. Here are some insulation techniques:
- Cavity Insulation: Filling wall cavities with insulation materials like fiberglass or rockwool stops sound from travelling through the walls. This is especially good for airborne noise.
- Attic Insulation: Insulating your attic not only improves energy efficiency but also creates a barrier that blocks external noise from entering your home. This is especially important for homes near busy roads or flight paths.
- Floor Insulation: Insulating between floors can reduce impact noise like footsteps or furniture movement. Rockwool or MLV are good for this purpose.
- Window and Door Insulation: Sealing gaps and cracks around windows and doors is a simple way to reduce noise infiltration. Adding weather stripping, caulking or even replacing single pane windows with double glazed ones can make a big difference.
- Layered Insulation: Combining different materials like spray foam with MLV can give you maximum noise reduction. This layered approach covers both airborne and impact noise.
