Introduction
2250 Light combines renowned Brüel & Kjær measurement excellence and the Type 2250
platform’s ease of use, in an efficient and versatile sound measurement instrument. Whether
you are addressing workplace noise compliance, environmental noise assessment, or product
noise certification, 2250 Light offers the functionality to meet your requirements. A unique
user-interface makes your measurements easier to perform with results that are easier to analyze
and report.
This data sheet describes the suite of software applications available for 2250 Light. All
instruments come with the Sound Level Meter Software for 2250 Light (BZ-7130) included.
Note: 2250 Light can be upgraded to a Type 2250 Hand-held Analyzer, to include more
features and applications such as advanced logging, sound recording or reverberation time
software. Please refer to Type 2250 Product Data BP 2025 for more information. The upgrade
is on an exchange basis, please contact you local Brüel & Kjær representative for details.
Applications
Workplace and Industrial Hygiene Noise Measurement Applications
2250 Light was developed with special interest for the measurement of workplace noise. The
comfortable and secure design feels safe in your hand. With the display located relatively close
to you, the buttons fall precisely where they need to be for a one thumb operated Start, Stop
and Save. The ‘Traffic Light’ indicator surrounding the Start/Pause pushbutton gives you an
immediate visual indication of measurement status – even in the brightest sunshine. The large,
high contrast, touch screen/display, lets you select parameters on the display, and 2250 Light
can memorise those setups for your next measurement.
As for occupational health noise
parameters, nothing was left out.
2250 Light can measure Fast and
Slow, A-weighted and C-Weighted
SPLs simultaneously, along with a
separately weighted peak detector,
so that the values you need to specify
hearing protection are immediately
on the display. Parallel analysis allows
you to compare a 3 dB exchange
rate average measurement with a
selectable alternate 4, 5 or 6 dB ex-
change rate, including separate
dose, expected dose and exposure
values.
2250 Light also offers three independent threshold peak event counters, along with simultaneous
Fast, Slow and Impulse RMS detectors, to assess impulsive noise.
When you add the optional 1/1-octave frequency analysis software option, you are ready to
instantly assess noise control and detailed hearing protection requirements for a surveyed
location. With 2250 Light there is no filter switching, or range changing, all the octaves are
measured at the same instant, along with the broadband A- and C-weighted values. For even
more detail, add the 1/3-octave frequency analysis option. Instantly see the maximum and
average levels across 31 frequency bands spanning three decades from 12.5Hz to 16 kHz.
