NIOSH Noise Exposure Data By Work Area
![NIOSH Noise Exposure Data By Work Area](https://www.johnsnowlabs.com/wp-content/uploads/2018/09/normal/Occupational-Health-And-Safety.png)
The dataset contains workplace noise measurement results collected during health hazards evaluation surveys from 1996 to 2013 for over 580 area noise level assessments. The collected data about exposure are based on OSHA and NIOSH assessment criteria and are accompanied by description of location, industry, working area, the activity that generates exposure, as well as other variables.

Description
The source of data is provided by The National Institute for Occupational Safety and Health (NIOSH), whose mission is to develop new knowledge in the field of occupational safety and health and to transfer that knowledge into practice.
Health hazards evaluations (HHEs) are requested by employees, 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. It also includes the following information: U.S. state or territory; National Occupational Research Agenda (NORA) sector; facility description; type of dosimeter or sound level meter used; noise-generating activities; location of noise measurements; start and end date for site visit; duration of noise measurement; and results in decibels A-weighted (dBA) and percent dose according to OSHA and NIOSH noise measurement criteria. This dataset is an ongoing project and will be updated at least yearly to add the most recent HHE noise measurement data.
All noise measurements were collected by NIOSH investigators as part of a health hazard evaluation. Data were extracted from the final report and, in some cases, augmented from investigator’s records. Administrative and observational information was extracted from the final report. The Health Hazard Evaluation Program has an extensive internal review process for its reports. Data entered into the database underwent a 10 percent random check to ensure accurate entry.
Area noise levels and octave band noise frequency measurements (measurement of noise in either single octave band or one-third octave band noise frequencies) were measured with integrating sound level meters (SLMs) and octave band noise frequency analyzers. The SLMs were equipped with 0.5 or 0.25-inch random incidence microphones (Type 1). During measurements, the SLMs were either hand-held or mounted on a tripod at a height of approximately 4 to 6 feet.
Because data related to measurements results in some cases were reported as singular or as interval of values (for the same variable), the lower and upper interval limits were placed in distinct fields (columns), along with singular values in each of the two fields. At the same time, in order to ensure the possibility to determine which of the values were reported as interval, a field that signals this aspect has been created.
