Choosing The Right Hearing Protection
It is critical to use adequate hearing protection to avoid long lasting damage. Permanent hearing loss can result from extended exposure to unsafe levels of sound. This type of hearing loss is irreversible and cannot be corrected with hearing aids or other equipment. In addition to temporary or permanent hearing loss, loud noises can also create physical and psychological stress and interfere with productivity and communication.
