Measures necessary for an effective hearing conservation program were described and discussed. Several industries and individual work places have established hearing protection programs which require the comprehensive and coordinated efforts of factory administrators, safety personnel, and employees. For a hearing conservation program to be effective it must include a noise survey conducted at the work site, engineering controls, administrative controls, audiometric evaluation, hearing protectors, worker education and training, and accurate recordkeeping. A hearing conservation program must be integrated into the total safety program at the facility. The workers should also be encouraged to take steps to protect their hearing away from the job. Additional steps were offered to make hearing conservation programs more effective. First, a commitment must be made to excellence in the program, not just meeting the minimum requirements. Secondly, a key person should be designated as the contact person and implementor of the program. Thirdly, operating procedures should be kept simple and have a continuity. Fourthly, a regular review of the hearing conservation program should be made to allow modifications of operating procedures and safety goals to be met.
