Management Techniques to Prevent Noise Disputes | How Apartment Soundproofing Works and the Measures Management Companies Should Communicate to Residents

Noise-related disputes are among the most frequent complaints in rental property management. To prevent issues as a management company, it is important to correctly understand how sound travels and provide residents with appropriate information and practical countermeasures.

Why do everyday sounds feel more noticeable in apartments?

There are two ways that sound is transmitted.

What is airborne sound?

Airborne sound refers to sound that is emitted and reaches others through the air.This includes voices, television audio, and the operating noise of equipment. It generally becomes weaker as distance increases and as barriers are introduced. In general, higher-frequency sounds are considered easier to block than lower-frequency sounds.

What is structure-borne sound?

Structure-borne sound occurs when vibration travels through floors, walls, and other parts of a building and is then radiated as sound.This includes toilet noise, water supply and drainage noise, footsteps, and the sound of doors opening and closing. It is influenced more by a building's structure and materials than by distance or obstacles, and many complaints described as "not knowing where the sound is coming from" fall into this category.

What measures should management companies communicate to prevent noise disputes?

Measures for vibration noise from household appliances

Guide residents to use washing machines and vacuum cleaners with consideration for the time of day. In addition, older appliances tend to become louder during operation, so residents should be encouraged to respond promptly when malfunctions or unusual noises occur.

Measures for residential fixtures and furniture

Consideration for bathing hours, closing doors quietly, and attaching caps to furniture legs are all examples of everyday living habits that can significantly reduce noise.

Measures for AV equipment and musical instruments

Inform residents that loud-volume use late at night or early in the morning is prohibited, and advise them not to place speakers against walls. It is important to clearly state in the rules that musical instrument performance is generally prohibited in apartments without dedicated soundproofing work.

Measures for everyday living noise

Residents should be asked to be mindful not only of their own noise, but also of noise from visitors and pets. Including pet training and measures to prevent unnecessary barking in the occupancy rules can help prevent problems later.

What soundproofing items can residents use on their own?

Large-scale soundproofing work is generally not possible in rental housing. By introducing the following three items to residents, management companies can encourage improvements through residents' own efforts.

• Soundproof mats (sheets):Simply placing them on the floor helps reduce vibrations transmitted to the unit below. Cork and low-resilience materials also blend easily with interior spaces
• Soundproof panels:Applied to walls to help prevent sound leakage to neighboring units. There are also many renter-friendly peel-and-remove options
• Soundproof curtains:Effective both for blocking noise from outside and for preventing indoor sound from leaking out

Frequently Asked Questions (FAQ)

Q1. When a noise complaint is received, what should a management company do first?

First, hear the details from the complainant, including the date and time, the type of sound, and the frequency, and keep a record. After that, the standard initial response is to send a notice of caution to the resident in the relevant floor or unit.

Q2. Is noise regulated by law?

There is generally no direct legal regulation for ordinary living noise, and much depends on individual perception. It is effective to define such matters in condominium management rules or as prohibited acts under the lease agreement.

Q3. Do noise-control measures differ between wooden apartment buildings and reinforced concrete buildings?

Yes. Because wooden buildings tend to have lower sound insulation, the use of soundproof mats and soundproof panels is particularly important. Even in reinforced concrete buildings, structure-borne sound can still travel easily, so similar measures remain effective.

Q4. What should be done if repeated warnings to a resident about noise still do not lead to improvement?

A phased response should be taken: written warning, notice of lease violation, and ultimately a recommendation to vacate. Consultation with a lawyer should also be considered when necessary.

Q5. Is soundproofing work possible even in rental properties?

Yes, if the owner's permission is obtained. However, the decision should be made after taking restoration costs at move-out into account.
