After reference audiometric testing has been undertaken to determine the baseline hearing of a person, subsequent monitoring audiograms can be used to assess whether a person’s hearing has been significantly affected due to noise exposure. Monitoring audiograms can be used in two ways:
- Assess temporary threshold shifts
- Determine permanent hearing loss
Monitoring audiograms are generally conducted onsite at the workplace with mobile audiometric units, close to, or at the end of the workers shift. The monitoring audiogram is then compared to the initial reference or baseline audiometric testing to determine whether there has been a threshold shift (which may be either temporary or permanent).
