“…For hearing protection devices to be successfully implemented, it is vital to count on employees own willingness towards its use, the model of the device and the adaptation of the equipment insinde employees' external auditory canal. Such features neglected can cause decrease in the level of hearing protection, if compared to what is obtained in the laboratory 18 .…”
