the first part of this program is to find out which workers are affected by the noise that is over the exposure action value. once the workers have been found, they each need to do a hearing test. this will help employers figure out how much hearing protection they will need to keep their workers safe as well as be able to compare the hearing level of the workers at this time to hearing levels later on. if there are large changes, that usually means that workers need more help with their hearing health.
