Common Causes of Noise in the Kitchen

The kitchen is one of the main hubs of activity in most homes. As a result, kitchens can often be some of the noisiest rooms in a house. There are many sources that contribute to kitchen noise pollution and make this space loud and disruptive.

Some of the most common causes of noise in kitchen areas include:

  • Using kitchen appliances: Appliances like blenders, food processors, garbage disposals, dishwashers, refrigerators, and more generate significant noise when running. The sounds of appliances chopping, grinding, whirring, and rumbling can be very loud and intrusive.
  • Closing cupboards and drawers: The banging of cupboard doors and drawers opening and closing creates startling bursts of noise, especially if the cupboards are loose or don’t have soft-close hinges.
  • Cooking sounds: The sounds of cooking–like frying, boiling water, sizzling, etc.–add to the background noise level. Pots and pans banging around also make plenty of noise.
  • Running water: The sound of water running from faucets and down drains contributes to ambient noise, as does the sound of a running dishwasher.
  • Conversations: People chatting, listening to music/podcasts, etc. also increases the noise level substantially.

All these sounds can make the kitchen a loud, chaotic place. The constant noise can make it hard to hear, converse, make phone calls, or just relax in the kitchen area. Finding ways to reduce noise is important for creating a more peaceful environment.

Soundproofing Materials to Use in the Kitchen

When it comes to reducing noise in your kitchen, using the right soundproofing materials and products is key. There are a variety of effective options designed to block, absorb, or dampen sounds.

Mass Loaded Vinyl

Mass loaded vinyl (MLV) is one of the most effective noise blocking materials available. This dense, heavy, flexible vinyl contains barium salts or other mineral fillers that make it excellent at impeding the transmission of sound vibrations. MLV works by providing a sound barrier thanks to its limp, plasticized properties and high density of 1 to 2 pounds per square foot. This density blocks mid-to-low frequency sounds very well.

MLV can be installed in a few different ways to reduce kitchen noise:

  • Apply 1-2 layers beneath laminate, vinyl, or tile flooring to block impact and airborne noise from transferring through floors.
  • Use MLV sheets on walls, adhered with construction adhesive. This creates a soundproof barrier stopping noise coming from adjoining rooms.
  • Make DIY MLV soundproofing curtains to cover kitchen windows. The heavy layering blocks outside noise.

Acoustic Caulk

Filling all cracks, gaps, openings, and crevices with acoustic caulk is important for sealing sound leaks that allow noise to transfer. Acoustic caulk contains noise dampening fillers and provides excellent adhesion. When applied properly, it dries into a flexible airtight barrier that prevents airborne noise from passing through vulnerable spots.

Be sure to apply acoustic caulk:

  • Around the perimeter edges of windows and doors to seal sound leaks
  • Along wall trim, corners, baseboards, and crown molding
  • Around outlets, pipes, vents, fixtures, and any openings
  • Between countertops, cabinets, and backsplashes

Acoustic Panels

Acoustic panels, also called acoustic foam tiles, are great for absorbing extraneous sounds and preventing echo buildup. Panels are made from sound absorbing materials like polyurethane foam or fiberglass. They work by trapping sound waves and dissipating the energy so that less noise reflects around the room.

Because panels dampen reverberation and high frequencies, they are ideal for placement:

  • On walls – reduces noise bounce
  • Inside cabinets – absorbs sound when doors open
  • On the ceiling – stops echo from buildup

Various thickness and density panels are available to target different frequency absorption needs.

Soundproofing Techniques for Appliances

Kitchen appliances are major contributors to noise pollution in this busy room. Luckily, there are ways to reduce the amount of noise that comes from essential appliances like refrigerators, dishwashers, and garbage disposals.

Use Sound-Absorbing Mats

Placing appliances on mats made of noise-blocking materials is an effective way to dampen vibration sounds. Materials like recycled rubber, cork, or even thick folded towels, absorb appliance vibrations instead of letting that energy transfer into the floor and surrounding cabinets. This reduces the humming and rumbling sounds appliances can generate.

Install Perimeter Gaskets

Adhesive rubber or foam gaskets can be installed around the perimeter base of appliances to act as a buffer. This includes dishwashers, refrigerators, and any freestanding or built-in appliances. The gaskets compress when the appliance is pushed into place, sealing gaps and blocking sound leakage. This prevents appliance noise from emanating out.

Build Custom Soundproof Boxes

For very noisy appliances like garbage disposals, you can build a custom soundproof box enclosure. Use MLV lined walls attached with acoustic caulk to fully contain the appliance and block noise. Make sure to include ventilation holes so the unit doesn’t overheat. The soundproof box traps all the noise inside.

Choose Quieter Models

When replacing old appliances, select models designed to operate more quietly. Newer appliance technology and noise dampening features can dramatically cut down on noise levels. Compare sone ratings (quietness measurement) and customer reviews to choose the quietest dishwasher, fridge, etc.

Soundproofing Techniques for Appliances

Kitchen appliances are major noise makers, but thankfully there are effective ways to reduce the amount of noise produced by refrigerators, dishwashers, garbage disposals, and other units.

Use Sound-Absorbing Mats

Placing appliances on mats made from sound dampening materials is an excellent way to absorb vibration noises before they amplify. Materials like recycled rubber, cork, felt, and even folded towels, act as buffers that prevent appliance vibrations from transferring into surrounding surfaces. This significantly reduces the humming, rumbling, and rattling sounds appliances can create.

Look for appliance mats that are at least 1/4 inch thick for adequate noise blocking. Cut the mats to fit the dimensions of freestanding appliances like refrigerators. For built-in units like dishwashers, cut mats to line the interior base where vibrations originate. The more contact between the mat and appliance, the better the noise reduction.

Install Perimeter Gaskets

Adhesive rubber or foam gaskets can be installed around the entire perimeter base of appliances to act as noise barriers. The compressible gaskets help seal gaps that allow noise leakage. When the appliance is pushed into place, the gasket material compresses and creates a tight noise-blocking seal.

Foam tape gaskets work well for retrofitting existing appliances. Or install custom cut rubber gaskets for a more permanent seal. Use gaskets at least 1/4 inch thick for optimal noise blocking. Be sure to clean and degrease surfaces so the adhesive adheres tightly.

Build Custom Soundproof Boxes

For very noisy appliances like garbage disposals, you can build a custom soundproof enclosure box. Use doubled up MLV material lined with mass loaded vinyl on all interior walls. Seal all edges and seams with acoustic caulk to contain noise. Make sure to include ventilation holes on the top so the unit doesn’t overheat.

The rigid, airtight box traps all the grinding noise inside. You can build boxes to fit around and over the appliance easily. Just be sure to allow openings for plumbing, wiring, and access. This is the most effective method for significantly reducing noise from obtrusive appliances.

Choose Quieter Models

When shopping for new appliances, compare noise ratings and customer reviews to select the quietest models. Look for features like insulation, vibration damping, air flow optimization, and noise reducing technologies that dramatically cut down on noise production.

Newer, high-efficiency appliance models tend to operate much more quietly than older units, making this an effective long-term strategy as you update appliances over time. With careful selection, it’s possible to have a kitchen full of appliances that don’t interfere with conversations or relaxation time.

Techniques for Soundproofing Kitchen’s Walls, Floors and Ceilings

Double Up Drywall on Walls

Adding a second layer of drywall is one of the most effective DIY methods for reducing noise transmission through walls. Stagger the seams between the two layers so they do not align. This prevents sound from passing through vulnerable seams. Green glue applied between layers adds damping.

Use 5/8″ thick drywall sheets for the second layer. Screw the sheets through to the wall studs, but do not screw into the existing drywall layer – let the green glue provide isolation between layers. Caulk acoustic sealant along the perimeter before taping for an airtight seal. The extra mass blocks more noise vibrations.

Seal Electrical Boxes and Plumbing

Gaps around switches, outlets, pipes, vents, and wiring penetrations allow noise leakage. Seal these thoroughly with acrylic latex caulk or other flexible acoustic sealant.

For outlets, apply acoustic putty pads under and around the electrical box before installing the outlet covers. The putty molds to fill gaps. Use putty/caulk on box extrusions and wire holes too. Silicone-based caulk adheres well to glossy pipes, making it ideal for plumbing noise prevention.

Insulate Wall Cavities

Injecting fluffy insulation like rockwool or cellulose into wall cavities adds mass and damping between walls. This reduces noise transfer and blocks sounds from transmitting through.

Combine insulation with 1-2 layers of MLV mats attached to wall studs using screws and construction adhesive. The MLV acts as a noise barrier while the insulation stops cavity resonance. Seal all seams and edges with acoustic caulk as well. The layered approach creates a soundproof sandwich.

Add Drop Ceiling Tiles

A dropped ceiling with acoustic ceiling tiles is a straightforward upgrade that helps absorb ambient noise in the kitchen. The panels dissipate sound energy and prevent echoes from amplifying noise.

Look for ceiling tiles rated NRC 0.55 or higher. Fiberglass, mineral wool, and recycled cotton tiles work well to dampen sound. Install the tiles in a grid system suspended below the existing ceiling. Overall ceiling height is reduced, but noise is also reduced.

Use Floor Underlayments

Applying sound dampening underlayments beneath floor tiles and laminate provides noise reduction from footsteps and dropped items. Look for underlayments made of cork, recycled rubber, or foam that reduce impact noise transmission into lower floors in multilevel homes.

Soundproofing Windows, Doors, and Vents

Openings like windows, doors, and vents also need special attention when soundproofing a kitchen. These spots often allow significant noise transfer from outside areas into the kitchen.

Acoustic Curtains on Windows

Hanging heavy, multilayered acoustic curtains over kitchen windows helps block outside noise like traffic from entering through the glass. Choose mass loaded vinyl or quilted curtains with insulation or foam to optimize noise absorption. Ensure curtains form an airtight seal against walls around the edges when drawn.

For best results, install thick PVC or vinyl windows with built-in noise damping chambers. Acoustic laminated glass also reduces noise transmission through windows.

Weatherstrip Doors and Frames

Apply plush weatherstripping tape and sealant around the entire perimeter of door frames to seal noise gaps. Quality weatherstripping compresses when the door is closed to block sound leakage around the edges and bottom.

For the bottom door gap, install door sweeps or gaskets. These sweep the floor when closed to prevent noise coming through the space beneath doors. Adjustable sweeps fit most door types.

Seal Vents and Ducts

Vibration and noises from ducts and vents can transfer through walls and ceilings. Use acoustic duct sealant/putty around all HVAC ducting openings and vents to prevent noise escape. For bathroom or kitchen vents, replace standard units with humidity sensing vents or install sone-rated quiet ventilation fans.

By thoroughly sealing all openings, you stop potential sound leakage points that allow noise to travel between rooms and enter from outside the home.

DIY vs Professional Soundproofing

When undertaking kitchen soundproofing, you can either take on projects yourself or hire professional contractors. There are benefits to each approach.

DIY Soundproofing Options

Many effective soundproofing techniques can be managed as DIY projects. For example:

  • Installing acoustic curtains and window treatments
  • Applying acoustic caulk and outlet seals
  • Laying sound-absorbing mats under appliances
  • Hanging acoustic panels and foam tiles
  • Weatherstripping doors and windows

These straightforward fixes are affordable and accessible for DIYers. Basic materials can be purchased at hardware stores or ordered online ready for home installation.

Professional Soundproofing

For more complex soundproofing that involves construction, it is often best to hire contractors. Professionals have the expertise to handle projects like:

  • Building custom soundproof boxes around loud appliances
  • Installing MLV sheets and isolation clips on walls
  • Adding mass loaded vinyl barriers beneath flooring
  • Applying multiple layers of drywall with green glue
  • Spraying insulation into wall cavities

Pros have the right tools and skills for meticulous installation. Their work also meets building codes.
