Waking up late at night from a construction site drill? Is the humming sound of your air conditioner like a concussion? Are construction noise and low-frequency vibrations giving you a headache? Don't worry! This "Noise Reduction First Aid Kit" will give you a 3-minute solution, offering step-by-step guidance on how to combat noise pollution using legal and technical means!

1. Construction parties must read: The "silent rule" of construction period management

1. The golden formula for staggered construction

- Hard work during the day, silence 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 sorting) at night.

- “Quiet Hour” Compensation: Residents are notified in advance on weekends to shorten construction periods in exchange for quiet rest days and reduce the risk of complaints.

2. High-tech noise reduction equipment

- Noise barrier wall: 3-meter-high sound-absorbing panels are built around the construction site, reducing noise by 15-20 decibels (measured data).

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

2. Property management/owners: low-cost blocking of low-frequency vibrations

1. DIY Vibration Isolation Tool

- Elevator shaft sound insulation: Installing rubber shock-absorbing pads on elevator tracks costs 50 yuan/meter and can reduce vibration transmission by 80%.

- Air conditioner outdoor unit "silencer cover": Wrap the equipment with polyester fiber sound-absorbing cotton and match it with a sound insulation baffle to reduce decibels by 30%.

2. A "Quick, Accurate, and Ruthless" Guide to Defending Your Rights

- Three-piece evidence collection kit: mobile decibel app ("Noise Assistant" is recommended), video records, and property management communication records.

- Direct complaint channel: Dial the 12369 environmental protection hotline or report through the "12345 Citizen Hotline" APP with one click, and you will receive a response within 72 hours!

3. Residents’ Self-help: Low-cost Soundproofing Tips

- "Vibration trap" floor: Lay 3cm thick sound insulation felt + floating floor keels under the wooden floor to block the sound transmitted by the floor (cost is about 80 yuan/㎡).

- "White noise" countermeasure: Play the sound of rain and waves to cover up low-frequency humming. It has been tested to improve sleep quality by 50%.
