Assessment of Acoustic Noise Generated from Machines in a Mechanical Workshop Using 1-Octave Band Frequency Analysis
Abstract: Acoustic noise is one of the prominent occupational health hazards, particularly in manufacturing and process industries. Prolonged exposure to loud noise can cause noise induced hearing loss of the exposed personnel. Limiting the exposure to noise intensity within its permissible exposure limit is adopted as one of the administrative control measures to reduce the risk of hearing loss. However, frequency specific assessment of occupational noise exposure is limited. Here, we …
