Brüel & Kjær Logging Sound Level Meters

Sound-Level-Meter-MainAn indispensable option for community noise is Logging software and Sound Recording software. This software upgrade is available on the Brüel & Kjær 2250 Sound Level Meter.

This provides key advantages over taking single measurements, namely:

  • Staff can deploy and retrieve instrument without remaining onsite
  • Untrained staff can drop off and collect the pre-configured instrument
  • Detailed time histories can be obtained
  • Sound recordings can take place based on noise level trigger thresholds

Key features which make the 2250 ideal for this purpose include:

  • Exceptionally low noise floor (< 18dBA )
  • Very wide single dynamic range (20 – 140 dB)
  • 100ms Logging (10 samples per second) as well as
  • Clock synchronized logging e.g. 1 minute, 15 minutes or 1 hour
  • MP3 / WAV file sound recording onto large CF / SD memory cards
