Sound transfer path analysis to model the vibroacoustic behavior of a commercial earmuff
Journal of the American Society of Acoustics
Hearing protection devices (HPD), such as earmuffs, are widely used to protect workers from noisy environments. Numerical predictive tools can be used to simulate the vibroacoustic behavior of earmuffs and thus assess their sound attenuation and improve their acoustical design. The present work describes the implementation of a vibroacoustic finite element numerical model of an earmuff coupled to a rigid baffle in the frequency range from 20 to 5000 Hz. An experimental assessment of the sound transfer paths
Development of an equivalent solid model to predict the vibroacoustic behaviour of earmuff cushions
Canadian Acoustics
A study that examines the relevance of using an equivalent isotropic visco-elastic solid model to capture the sound transmission law of an annular cushion from a commercial earmuff is presented. Ten cushions from a hygienic spare set are studied. They are mounted on a shaker and submitted to the weight of three metal blocks with masses of 1.15kg, 1.65kg and 2.13 kg, representing the force applied by the head band when the earmuffs are positioned on the head. Holes are glued with cyanoacrylate glue, when eac
