NIOSH Health Hazard Evaluation Program Noise Measurement Database

This noise database was developed to provide researchers and other interested stakeholders with noise measurement results that the National Institute for Occupational Safety and Health (NIOSH) has collected during health hazard evaluation (HHE) surveys from 1996 through 2013. HHEs are requested by employees or their representatives, or employers, to help learn whether health hazards are present at their workplace. The scope of HHEs varies based on the requestors’ concerns and the NIOSH project officers’ professional judgment. Only noise measurement results are included in this database; however, many HHEs include evaluation of exposures other than noise. Individual HHE reports are published on the NIOSH website. When available, the database provides a direct link to the HHE report for each of the noise measurement results.\n\nThe noise database contains workplace noise measurement results from 77 HHE reports, including over 808 personal noise exposure measurements and 582 area noise measurements. It also includes the following information: U.S. state or territory; Occupational Safety and Health Administration (OSHA) region; National Occupational Research Agenda (NORA) sector; North American Industry Classification System (NAICS) code; facility description; type of dosimeter or sound level meter used; whether a hearing conservation program was in place; whether a hearing protection was used; whether octave band data was collected; job title; noise-generating activities; location of noise measurements; start and end date for site visit; type (full-shift, partial-shift, or task-based) and duration of noise measurement; type of noise (continuous, impulsive, or intermittent); exposure to ototoxic chemicals; and results in decibels A-weighted (dBA) and percent dose according to OSHA and NIOSH noise measurement criteria. This database is an ongoing project and will be updated at least yearly to add the most recent HHE noise measurement data.

本噪声数据库旨在为研究人员及其他相关利益方提供美国国家职业安全与健康研究所（National Institute for Occupational Safety and Health, NIOSH）于1996年至2013年间在健康危害评估（Health Hazard Evaluation, HHE）调研中收集的噪声测量结果。健康危害评估申请由雇员、其代表或雇主提出，用于协助判断其工作场所是否存在健康危害。评估的范围取决于申请者的关注点以及NIOSH项目官员的专业判断。本数据库仅收录噪声测量结果，但多数健康危害评估会对噪声以外的暴露情况开展评估。每份单独的健康危害评估报告均发布于NIOSH官方网站。若可获取，本数据库将为每条噪声测量结果提供对应健康危害评估报告的直接链接。

本噪声数据库收录了来自77份健康危害评估报告的工作场所噪声测量结果，其中包含超过808项个体噪声暴露测量数据与582项区域噪声测量数据。本数据库同时涵盖以下信息：美国州份或领地、美国职业安全与健康管理局（Occupational Safety and Health Administration, OSHA）辖区、国家职业研究议程（National Occupational Research Agenda, NORA）行业领域、北美行业分类系统（North American Industry Classification System, NAICS）代码、设施描述、所使用的剂量计或声级计类型、是否已实施听力保护计划、是否使用听力防护装备、是否采集了倍频程数据、岗位名称、噪声产生活动、噪声测量点位、现场探访起止日期、噪声测量的类型（轮班全程、轮班部分时段或基于任务）与时长、噪声类型（连续型、脉冲型或间歇型）、耳毒性化学品暴露情况，以及符合OSHA与NIOSH噪声测量标准的A计权分贝（dBA）结果与剂量百分比。本数据库为持续更新项目，将至少每年更新一次，以纳入最新的健康危害评估噪声测量数据。
