Handheld Solution for Occupational Health

XL2 Audio and Acoustic Analyzer
with M2210 Measurement Microphone

• Handheld and compact design for field applications
• Calibrated acoustic measurement system
• Improved efficiency with dedicated measurements profiles and appending test results to previous data records
• Automated sound level documentation and high resolution wav-file recording in 24 Bit / 48 kHz format to SD Card

• Sound pressure level SPL
  for industrial sound pollution monitoring
  - LAeq (averaged sound level with A-weighting)
  - LCpeak (peak sound level with C-weighting)
   
• Stack Light
  Alarms at exceeding sound levels, thus employees near the test station are notified immediately.
   
• Noise exposure level LEX,8h
  The Noise at Work Directive 2003/10/EC reduces the risk of hearing damage for employees. The action limits are
  

  	LEX,8h	LCpeak	Action
  Lower limit value	80 dB(A)	135 dB	recommend wearing hearing protectors
  Upper limit value	85 dB(A)	137 dB	hearing protectors must be worn and noise level reduced as possible
  Exposure limit	87 dB(A)	140 dB	employee with hearing protectors shall never exceed this limits

• At steady noise (applies for LAS deviation is < 5 dB)
  Measure the LAeq over a few minutes, the resulting LAeq represents the noise exposure level of the complete 8 hours period LEX,8h = LAeq. The following formula applies for a daily exposure time ≠ 8 hours:
  LEX,8h = LAeq + 10 x log ( T / 8 hours )
   
• At steady noise with stepwise level variations
  (applies for steady noise at clearly distinguishable levels)
  Measure the LAeq at the different levels and note the corresponding exposure time. Enter all data in the NTi Audio noise exposure level post processing form; the LEX,8h will be calculated and displayed.

• At varying noise levels
  LEX,8h = LAeq measured for 8 hours.
