This "noise reduction first aid kit" will help you find solutions in 3 minutes, teaching you step-by-step how to fight noise pollution using legal means and practical skills!

I. Essential Reading for Construction Teams: The "Silent Rule" of Construction Schedule Management

1. The Golden Formula for "Staggered Construction"

- Focus on high-noise operations during the day and keep quiet at night: Concentrate high-noise operations such as piling and cutting during the day (6:00-22:00), and only retain low-noise processes (such as material handling) at night.

- Compensation for "quiet periods": Residents are notified in advance on weekends, the construction period is shortened in exchange for quiet rest days, and the risk of complaints is reduced.

2. Cutting-edge noise reduction equipment

- Sound barrier wall: A 3-meter-high sound-absorbing panel is built around the construction site, which reduces noise by 15-20 decibels (actual measurement data).

- Low-noise equipment replacement: For example, replacing traditional drilling rigs with "silent crushers" reduces noise from 90 decibels to 75 decibels.

II. Property Management/Owners: Low-Cost Blocking of Low-Frequency Vibrations

1. DIY Solution for "Vibration Isolation Device"

- Elevator shaft sound insulation: Install rubber vibration damping pads on the elevator track, costing 50 yuan/meter, which can reduce vibration transmission by 80%.

- Air conditioner outdoor unit "soundproof cover": The equipment is wrapped with polyester fiber sound-absorbing cotton and paired with sound insulation baffles, reducing decibels by 30%.

2. A Guide to Quick, Accurate, and Decisive Rights Protection

- Three essential pieces of evidence: a mobile app called "Decibel" (recommended: "Noise Assistant"), video recordings, and communication records with property management.

- Direct complaint channels: Call the 12369 environmental hotline or report with one click through the "12345 Citizen Hotline" APP. We guarantee a response within 72 hours!

III. Residents' Self-Help: Low-Cost Soundproofing Tips

- "Vibration Trap" Floor: Lay a 3cm thick sound insulation felt and a floating floor joist under the wooden floor to block the transmission of sound from the floor slab (cost approximately 80 yuan/㎡).

- "White noise" countermeasure: Playing rain or ocean waves can mask low-frequency humming, and tests have shown that it can improve sleep quality by 50%.
