Should be what?
Analyzed to determine the potential hazard,
Resurvey 30 days after any significant modifications or changes in work routine which could impact the noise exposure level.
Records of noise measurements shall be kept by the measuring activity for how long?
50 years.
What shall be assigned to all potentially hazardous noise areas and operations?

Reference hearing test.
Monitoring Audiogram?
For personnel in HCP,
Annual exam is required,
Recorded on DD-2216.
What is an STS?
Significant Threshold Shift (STS),
A change in hearing threshold relative to the current reference audiogram of an average of 10 dB or more at 2000, 3000, and 4000 Hz in either ear.
Positive STS?
Poorer Hearing.
Negative STS?
Better Hearing.
If the STS is negative, the hearing levels of the monitoring audiogram are better than the reference audiogram, what could be the cause?
Either the Reference or monitoring audiogram may be in error.
If a patient has a negative STS, when do you retest them?

If the negative STS retest showed no STS, assume what?
That the monitoring audiogram was in error.
