Precision Integrating Sound Level Meter Type 2236 is a Type 1 instrument, de-
signed to meet stringent standards in environmental- and occupational-noise meas-
urement.
As Type 2236 is designed to fulfil the national standards and directives, all param-
eters can be obtained from the one measurement. This saves both time and money.
Measurements are displayed on a large (4 lines, 16 characters/line) LCD screen.
The SPL (RMS) is continuously monitored on a quasi-analogue display. The digital
output allows interfacing with personal computers and printers, for further data
processing/presentation and printing.
The linearly-weighted AC output allows for a direct calibrated recording (on Digital
Audio Tape, for example), enabling later analysis.

Description
Precision Integrating Sound Level
Meter Type 2236 has been designed
specifically for environmental- and
occupational-noise measurements.
Double-detector
A unique feature of the 2236 is that
RMS and Peak detection occurs in
parallel. In this way the sound level
meter can display both the RMS val-
ue and the Peak value of the same
signal — particularly useful when
analyzing transients or impulses.
Intuitive User-interface
The clearly marked arrows and sym-
bols on the front panel, combined
with the large LCD screen (with back
light) make the sound level meter
very easy to learn and use. The dis-
play is clear and concise, and an in-
teractive dialog guides you through
your measurement, quickly and effi-
ciently. Warnings are also given when
you attempt to change a set-up pa-
rameter once you have started your
measurement.
Statistics
The sound level meter has three user-
definable L
N
values (only two fixed
ones for the International version).
With the USA and UKe models you
can also perform Level and Cumula-
tive Distributions on the results, al-
lowing basic statistics on the spot.
Real-time Clock
The 2236 sound level meter has a
real-time clock for marking results
with the date and time of any
measurement — particularly useful
for storing data for future use or pres-
