Abstract

Contents: Definition of Variables: hearing loss, noise, exposure; The Human Problems of Industrial Noise; Presbycusis; Requirements for Field Data; Continuous Exposure to Steady Noise: The Relation of Hearing Loss at Certain Frequencies to Octave Band Levels; Average Net Hearing Loss Contours; Trend Curves: Estimates of Average Net Hearing Loss; Confirmation of the Trend Curves; Limitations of Trend Curves: Spectra and Extrapolations; Limitations of Trend Curves: Intermittent Exposure and Non-Steady Noise; Limitations of Trend Curves: Temporary Threshold Shift; Reduction in Temporary Threshold Shift after Cessation of Exposure; Exposure to Low-Frequency Noise; Gross Hearing Losses in Three Hypothetical Groups; Intermittent Exposure to Steady Noise: Airplane Noise; Jet-Engine Noise; Intermittent Exposure: Riveting Noise; Impulsive Noise: Proof-firing; Impact Noise: Drop Forge; Relation of Threshold Shifts to Initial Audiograms.
