Soundproofing Tips by Appliance

You can apply various soundproofing techniques to reduce noise from major home appliances. The best methods depend on the type of appliance and main noise sources.

Refrigerators

As one of the most consistently noisy appliances, refrigerators are a key target for soundproofing. Here are some tips:

Install sound-dampening pads beneath the refrigerator to absorb vibration and rattling. Self-adhesive rubber pads work well.
Apply mass loaded vinyl (MLV) sheets to the walls around the refrigerator. MLV blocks noise by using heavy vinyl barriers.
Place thick rubber gasket material on doors and panels to block gaps where noise escapes.
Use a soundproof enclosure or insulation wrap specially designed for refrigerators.
Level freestanding refrigerators to minimize vibrations that cause noise.
Replace loud internal components like condenser fans with quieter models.

By layering several refrigerator soundproofing approaches, you can achieve noise reductions of 50 decibels or more.

Washing Machines

Due to intense spinning and vibration, washing machines naturally produce a lot of noise. Here are some washing machine soundproofing techniques:

Use sound-dampening pads beneath the washing machine to absorb vibration and noise transfer. These pads come in various thicknesses.
Construct a thick plywood enclosure around the washing machine area. Line the interior walls with MLV sheets. Leave the front open for access.
Attach thick weatherstripping around the washing machine opening to block noise escaping when the door is closed.
For front load washing machines, install a soundproof door that seals closed.
Replace loud internal components like motors or pumps with quieter versions.
Limit running washing machines at night to reduce noise disruptions.

With the right combination of washing machine soundproofing methods, you can decrease noise by more than 75%.

Dryers

Clothing dryers also generate significant operational noise. Soundproofing approaches include:

Use an external dryer vent silencer that connects to existing vents. This muffles noises flowing through vents.
Apply MLV sheets to the walls around the dryer area. Used alone or with enclosures, MLV blocks escaping noise.
Construct a dryer closet with soundproof walls to prevent noise transfer to other rooms.
Replace noisy dryer motors, fans, and heating elements with quieter components.
Allow greater distance between dryers and living spaces. Basement installations often work well.
Limit running dryers at night when appliance noises seem amplified.

Properly soundproofed dryer installations can reduce noise by 60-80% for a noticeably quieter operation.

Dishwashers

Dishwasher soundproofing is trickier because of the device’s integrated design. But you can still make dishwashers run more quietly using these methods:

Choose dishwashers with sound insulation built in. Many modern models advertise quieter sound profiles.
Install a soundproof dishwasher enclosure equipped with MLV sheets and noise-blocking materials.
Layer MLV sheets beneath dishwasher units if installing below counter level.
Replace loud dishwasher motors and pumps with quieter versions.
Allow sufficient clearance between dishwashers and other surfaces so vibration transfers less easily.
Run dishwashers during waking hours instead of at night when noise seems louder.

While not always possible to soundproof dishwashers completely, you can still reduce their bothersome noise by 50% or more.

DIY Soundproofing vs Professional

You can tackle appliance soundproofing yourself using do-it-yourself tips and materials. Or you can hire professional soundproofing companies to handle the project.

DIY soundproofing costs less but requires more effort on your part to design and install. Professional soundproofing costs more but delivers expert project execution.

The choice depends on your budget, skill level, and the scale of soundproofing required. Often a combined DIY and professional approach works best.

Complex professional installs using composite slabs and custom alloys offer the highest noise-blocking performance but cost thousands.

How to Measure Soundproofing Effectiveness

It is important to validate whether any appliance soundproofing actually achieves worthwhile noise reductions after installation. There are three main ways to measure effectiveness:

Use a Decibel Meter – Quantify before and after noise levels around appliances using an accurate decibel meter app or sound level probe. Look for reductions of at least 20dB at various spots around an appliance after soundproofing.
Listen for Noise Changes – Carefully listen as appliances operate before and after soundproofing and qualitatively assess noise reductions heard at different locations.
Feel for Vibrations – Pay attention to vibration through floors or surfaces before and after installing anti-vibration pads or damping materials. Less noticeable vibration equals an effective soundproofing upgrade.

Measure sound levels late at night when household background noise is minimized. Run appliances through a full cycle to capture any noise changes as internal components shift to different phases.

Record any noise observations for soundproofed appliances and retain receipts for soundproofing expenditures. This validates reductions achieved if longer-term performance issues ever occur.

Soundproofed Smart Home Integration

You can optionally integrate soundproofed appliances with smart home and IoT platforms using automation, voice commands, or mobile alerts. This allows you to:

Receive notifications if significant noise increases back to pre-soundproofed levels. This might indicate soundproofing degradation or new noise problems needing attention.
Monitor appliance usage cycles to understand typical noise patterns over days, weeks, and months post-soundproofing. Verifies continued noise reductions.
Change appliance settings like drum spins for smart washers and dryers to optimize cycles for lower noise.
Shift appliance run times to quieter periods using automation and scheduling.
Diagnose problems through recordings of appliance noises captured by smart speakers and microphones.

Smart integration maximizes the performance life of appliance sound treatments for sustained benefit. It also adds convenience controlling soundproofed appliances from mobile devices.
