The Navy Hearing Conservation Program aims to prevent noise-induced hearing loss. It involves identifying noise hazardous areas, implementing engineering controls to reduce noise levels when possible, posting hazard signs, providing hearing protection, and conducting medical monitoring with audiograms. Key program elements include conducting sound level surveys to determine hazardous noise areas, considering engineering controls first before resorting to personal protective equipment, using double hearing protection in very loud areas over 104dB, and giving all naval personnel baseline and periodic audiograms.
