The Best Noise-Reducing Flooring Solutions for Multi-Story Homes
Many people find the high noise level of various items on the floor of their multi-story home to be an unintended consequence. Furniture scraping, the sound of footsteps, and echoes between levels may seem like a minor annoyance when living in a multi-story home. If you’re trying to manage children running up and down the stairs, noise from high-traffic areas in a hallway or home theatre noise into bedrooms below, it’s imperative that you get the right materials to dampen the sound. To find acoustic peace, it is important to understand how sound moves through building assemblies and to choose building materials that absorb impact and are not conductors of vibrations to the home frame.
This course is designed to educate the student on the concepts of Household Noise and Acoustic Ratings.
When considering flooring materials, it is very important to understand the two primary types of such noise in multi-story buildings. Impact noise is caused by structural vibrations that travel down to the floor surface during impact events or when an object strikes the floor surface; examples of impact events include footsteps, dropped items, shifting chairs, etc. Airborne noise is noise from the air, like conversation, music or television noise. There are two industry standards to assess flooring materials: Impact Insulation Class for resistance to structure-borne impact sound and Sound Transmission Class for airborne sound transmission. Choosing materials with higher numbers in both metrics will provide better noise control throughout all the living spaces at the lowest level.
Luxury Vinyl Plank with Low-Outdoor Noise Transmission (LOW-Ownt) Underlayment.
The natural acoustic dampening properties, water resistance and durability of Luxury Vinyl Plank make it one of the most popular flooring options in modern residential spaces. High-quality vinyl has a flexible core that provides a natural ability to absorb kinetic impact as opposed to reflect sound waves like natural hardwood or ceramic tile. The modern planks can be acoustically dampened either by adding cork padding to the bottom or by using high-density acoustic foam backing, and this can significantly reduce footfall noise. In addition, floating panels of luxury vinyl over specially designed rubberised underlayment sheets create a second acoustic barrier, which helps to stop the impact energy from passing into the subfloor structure under them.
Natural Cork Flooring for Exceptional Sound Absorption
Natural cork is a sound-absorbing flooring option which is one of the best flooring options in residential properties. Cork is made up of millions of minute air-filled cellular chambers that serve as a natural buffer that retains thermal and acoustic vibrations. This special matrix of cells absorbs sound waves into harmless kinetic energy, thus blocking footstep echoes from passing down to rooms directly below. Today’s cork flooring options are available in an assortment of engineered planks and tiles with protective wear layers, perfect for the upper-level room, home office or nursery. Cork can also be used as a high-quality layer of underlayment under engineered wood and floating floors to enhance the sound isolation quality of the floor.
Carpet Tiles and High-Density Cushioning Systems.
In multi-story layouts, carpet continues to reign supreme for its ability to absorb sound. Tightly woven fabric fibres absorb impact sounds at the moment of impact, and soft surface textures block any airborne room echoes. These modern carpet tile systems are extremely practical, as they enable homeowners to lay carpet in high-traffic spaces, such as upper corridors or staircases, which are typically high-density modular. Carpet should be underlain with a high-density, high-quality polyurethane foam or heavy rubber carpet pad at all times, to provide maximum sound-dampening characteristics. Dense carpet pile coupled with resilient underpadding provides a formidable footstep barrier from top to bottom.
Specially designed to stop noise from escaping, Engineered Hardwood composite panels are a mix of specially formulated wood composite and acoustic barrier materials.
While many homeowners favour the timeless elegance of hardwood flooring, they fret about the noises of natural wood that can occur underfoot. Swinging hardwood flooring directly to subfloor joists conducts a lot of vibration down through the building structure, but when installed properly, engineered hardwood offers a much quieter option. Engineered wood planks are made of several layers of wood cross laminated to provide a more stable board and less reverberation. For maximum noise reduction, engineered hardwood should be installed over acoustic rubber membrane underlayment products or installed with sound-dampening underlayment products that are slightly flexible to provide physical separation from the vibrations in lower level ceiling assemblies.
Conclusion
Making a calm and quiet multi-level home depends on picking flooring materials which are designed to be extremely acoustically isolating. High density carpet systems, acoustically treated engineered wood, cushioned luxury vinyl, natural cork, and other sound reduction materials can help reduce distracting noise from footsteps and acoustic transmission between the different levels. The addition of targeted acoustic materials to upper-floor surfaces can make these rooms quiet and comfortable to live in, and create a great overall value for your property.
