售楼小姐说出大实话：买电梯房别选这3个楼层，坏处太多！

Core Viewpoint - The article emphasizes the importance of floor selection when purchasing elevator apartments, highlighting three specific floors to avoid due to potential issues that may arise after moving in [3][12]. Group 1: Floors to Avoid - The top floor is prone to extreme temperatures and has a high risk of water leakage, especially in areas with heavy rainfall [5]. - The ground floor, while convenient, suffers from noise and dust pollution from street traffic, and residents still incur elevator maintenance fees [6]. - The mid-level or waistline floor may appear aesthetically pleasing but can accumulate water and suffer from poor lighting, with potential radiation hazards from concentrated building utilities [7]. Group 2: Noise Reduction Techniques - For those who have already chosen undesirable floors, various renovation techniques can help mitigate noise issues, such as installing high-quality soundproof doors and double-glazed windows [8][9]. - Additional soundproofing methods include creating soundproof walls with acoustic materials, using solid wood flooring, and employing floating floor techniques to reduce sound transmission [9][10]. - Other strategies involve soundproofing ceilings, sealing wall openings, treating balconies for noise insulation, and wrapping drainage pipes with sound-absorbing materials [10][11].
