Table 2: Typical Measurement Tasks

Task Suggested Settings

Determine Noise Exposure of

Employees Working Near an

Impact Press

Use broad band ENV with 1 second period and EVT

enabled,

Measure Leq and LinPeak, Inspect period profiles,

Check events.

Measurements to Aid Selection of

Hearing Protection Suitable for the

Employees Above

Use

1

⁄

1

octave band real time SLM,

Store SPLmax spectra followed by L

eq

spectra,

Apply data to protector selection chart.

Reduce Noise Levels in Location

Adjacent to a Noise Source

Use

1

⁄

3

octave band real time SLM,

Compare stored SPL spectra from source with SPL

spectra from location,

Check for noise leaks/improvements.
