概括
城市噪音暴露被静态地图低估了. 个人监测显示,每日噪音剂量明显超过健康限制,这是由公共交通使用等流动行为驱动的.
科学领域:
- 环境健康 环境健康
- 城市规划 城市规划
- 声学 声学 在声学上.
背景情况:
- 传统的城市噪声评估依赖于静态的,住宅层面的年均地图.
- 这种方法可能低估了由于日常流动和接近各种噪声源而导致的个人噪声暴露.
研究的目的:
- 使用高分辨率传感器数据,将个人噪音暴露与模拟的噪音地图指标进行比较.
- 确定影响个人噪音暴露的社会经济和行为因素.
- 评估行为重新分配对日常个人噪音暴露的影响 (LAeq,24h).
主要方法:
- 利用了来自巴黎 (2018-2020年) MobiliSense队列259名参与者的数据.
- 配备参与者个人声压监测器,GPS接收器和加速度计.
- 通过移动调查收集的运输方式数据.
主要成果:
- 个人噪音暴露与建模的住宅水平有显著差异.
- 参与者在只有36%的日子里经历了低于55dB健康指南的噪音.
- 公共交通,特别是地下交通,对每日噪音剂量产生了不成比例的贡献 (9.5%的剂量占1.4%的时间).
结论:
- 个人移动性和行为是城市噪音暴露的关键决定因素.
- 静态住宅噪声评估低估了实际的个人暴露.
- 政策建议包括促进可步行城市,减少通勤时间,建立城市"安静区域"以恢复噪音.

Mechanistic Models: Compartment Models in Individual and Population Analysis
23
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

The Availability Heuristic
5.9K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Naturalistic Observations
15.3K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
