MONITOR, COMPUTE AND RECORD NOISE LEVELS
A fully automatic, portable table-top recording sound
level integrator that monitors, measures, computes and
records cumulative daily noise exposure in noise-prone
industrial and similar environments has been introduced
by Triplett Corporation, Bluffton, Ohio.
The new Integrator, Triplett Model 380, is designed to
measure the fractional noise exposure Cn/T n where C n
indicates the total permissible time at that level.
The Model 380 Integrator continually sums these
fractional exposures and displays the number on the
four-digit readout representing the percentage of
allowable exposure to which the instrument has been
subjected.

When the permissible limit is reached, a red warning
light glows, and an amber light is activated when an
instantaneous sound level surpasses 115 db. The paper
chart recorder provides a permanent, continuous record
on paper tape of the sound pressure level versus time over
a specified period to meet all legal requirements of the
noise Acts.
The strip chart provides a legal record to meet
Occupational Safety and Health Act (OSHA)
requirements. The unit has a detachable omni-directional,
