The NOISE (Non-Occupational Incidents, Situations and Events) Database: A new research tool

Abstract This paper describes the development of the NOISE (Non-Occupational Incidents, Situations and Events) Database. The NOISE database currently contains 536 separate leisure activities and events, including noise level measurements, (LAeq and LCpeak), and detailed information about the circumstances of each event. The data are organized into seven categories, in which high-noise events and activities can be identified. Thirty-five percent of events in the database were over 85 dB (the level at which noise is considered a risk according to workplace standards) and 3% were over 100 dB. Fourteen percent of events exceeded the acceptable workplace noise exposure limit of 1.01 Pa2h. The noise exposure levels recorded in the database can be used to identify high-risk leisure activities and to estimate individuals’ leisure noise exposures and make comparisons between leisure and workplace noise exposures.
