Complete Guide to Noise Management in Rental Apartments
Noise disputes in rental housing are a major source of stress for tenants. This guide from rental professionals explains noise types and causes, along with practical DIY soundproofing measures you can implement, how to consult with your property management company, and restoration obligations at move-out.
Noise in rental apartments and complexes falls into four main categories.
Footsteps and Vibrations from Adjacent Floors (Solid-Borne Noise)
Sound transmitted through vibrations in floors and walls. Common examples include footsteps from above, the sound of dragging chairs, and children jumping. Even in reinforced concrete buildings, thin floor slabs transmit sound easily. This is even more pronounced in wooden apartment buildings.
Neighbor's Noise (Airborne Sound)
Sound transmitted through the air, including television, conversation, music, and vibrations from washing machines. Properties with low sound insulation ratings (D values) are more affected, and this is often a problem in older buildings and inexpensive wooden apartments.
External Noise
Sound entering from outside the building, such as traffic from main roads, trains, construction noise, and voices from restaurants. Window air-tightness and soundproofing performance are key to addressing this.
Musical Instruments and Loud Sounds
Noise from musical instruments such as guitar, piano, or drum practice has a wide frequency range and is significantly more difficult to manage than ordinary household noise. Most rental properties prohibit musical instrument practice in their management rules, so checking the lease terms before moving in is essential.
DIY Soundproofing Measures You Can Implement
Even in rental properties, many soundproofing measures can be implemented within the scope of restoration to original condition.
Soundproof Carpets and Mats (Cost: ¥3,000–¥30,000)
This is the most effective measure for blocking solid-borne noise. The lower the LL rating (lightweight impact sound rating), the better the performance. Products with an LL rating around 45 provide noticeable results. While covering the entire room is ideal, you can also achieve significant noise reduction by initially covering high-traffic areas such as dining rooms and living rooms. For households with babies or children who run around, laying soundproof mats over interlocking mats provides additional benefits.
Soundproof Curtains (Cost: ¥5,000–¥30,000)
Effective for reducing external noise and traffic noise entering through windows. Choose products with a listed sound insulation rating, and cover from the curtain rod to the floor without gaps for best results. Layering them with existing curtains further increases effectiveness. Most products also provide blackout properties, offering additional benefits beyond soundproofing.
Window Seal Tape and Gap Sealing Tape (Cost: ¥500–¥2,000)
If noise leaks through gaps in window frames, EPDM rubber or urethane gap sealing tape available at home improvement stores can noticeably reduce external noise with simple application. This approach offers excellent cost-effectiveness and is recommended as the first measure for soundproofing beginners. Strips can be easily removed at move-out for full restoration.
Sound-Absorbing Panels and Soundproof Wall Materials (Cost: ¥5,000–¥50,000)
These absorb reflected sound within the room and reduce sound spread. Products are available for mounting on walls to prevent sound leakage to neighboring units, as well as standalone models that simply sit on the floor. For rentals, using double-sided tape or tension-mounted installation methods allows you to set them up without making holes in walls.

Steps to Take When Experiencing Noise Disturbance
If you experience noise disturbance, direct confrontation with the source can escalate the problem. Address the situation calmly by following these steps.
Step 1: Document the Situation
Make a record of when the noise occurs, which direction it comes from, what type of noise it is, and how frequently it happens. Recording decibel levels using a smartphone noise meter app provides concrete evidence useful when consulting later.
Step 2: Consult with Your Property Management Company or Condominium Association
Based on your records, contact your property management company (for rentals) or condominium association (for rented condominiums) in writing or by email. Using documented methods rather than verbal communication is important for creating a record. Property management companies have a duty to notify the tenant responsible for the noise, and typically respond by posting notices to the entire building.
Step 3: If the Problem Persists
If the problem continues after consulting with the management company, you may also contact your local authority's consultation desk (consumer life center or housing consultation service). If the noise exceeds reasonable tolerance levels, the situation may escalate to legal action, but first prioritize resolving the matter through the management company.
Important Note
Direct complaints to suspected neighbors carry a high risk of escalating into further conflict. Always have the management company handle the situation.
Tips to Avoid Being a Noise Source
Noise problems don't only happen to those affected—you may be the source. Keep these points in mind daily.
•Be mindful of noise during late night and early morning: Avoid using washing machines and vacuums after 10 p.m.
•Be conscious of your footsteps: Wear slippers indoors and walk from heel to toe
•Keep TV and music volume down: Use earphones or headphones at night
•Mind your manners when guests visit: Voice volume tends to increase when groups gather, so consciously lower your tone
•Musical instrument practice: Check management rules beforehand and follow designated practice hours
Even if you don't notice a sound, building structure may cause it to be heard loudly in adjacent or lower units. Greeting neighbors when you first move in and establishing good relationships help ensure smooth resolution should any problems arise.
Soundproofing Products and Restoration to Original Condition at Move-Out
Issues often arise at move-out regarding damage or stains caused by soundproofing products. The "Guidelines on Disputes and Restoration to Original Condition" published by the Ministry of Land, Infrastructure, Transport and Tourism state that normal wear and tear from ordinary use and age-related deterioration are not the tenant's responsibility for restoration. However, incorrect installation methods may result in repair cost claims.
Key Points to Prevent Restoration Disputes
•Avoid drilling holes or using strong double-sided tape to attach items (risks leaving marks or paint peeling)
•Choose sound-absorbing panels explicitly labeled as "rental-friendly" and "non-damaging to walls"
•Periodically flip soundproof carpets to allow air circulation and prevent mold
•Photograph the installation and removal process
At move-out, remove all installed products and compare the condition of walls and floors against photos taken at move-in. If damage or stains have appeared, consult with the management company before leaving to minimize disputes.
Noise problems in rental housing can typically be resolved or reduced through proper measures and good communication. Start with low-cost options like gap sealing tape and soundproof mats, then layer additional measures based on your building's characteristics and noise types. The best soundproofing strategy is maintaining daily awareness to be neither a victim nor a source of noise disturbance, ensuring a comfortable rental life.
