Bruel & Kjaer 2236D - Features
•Measuring environmental noise
•Measuring occupational noise
•Frequency analysis of sound sources
Precision Integrating Sound Level Meter Type 2236
is a Type 1 instrument, designed to meet stringent standards in environmental- and occupational-noise measurement.
As Type 2236 is designed to fulfil the national standards and directives, all parameters 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.
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 value and the Peak value of the same signal — particularly useful when analyzing transients or impulses.
•Conforms with IEC651 (1979) and 804 (1985) Type 1
•Conforms with ANSI S1.4 -1983 and Draft S1.43 -199X Type 1
•Calculates and displays LN values *
•Simultaneous RMS and Peak measurements with independent frequency weighting
•Automatic logging of results
•Performs complete statistical analyses
•40 records of manually stored results
•Automatic-start allows for unattended measurements
