The Extended Acoustic Pack supports the daily tasks of acoustic consultants. It offers additional features for sound level logging and acoustic measurements, such as recording linear wav-files, percentile statistics, sound exposure level, 100 ms logging, event monitoring, reverberation time RT60 in 1/3 octave resolution, Zoom-FFT with 0.4 Hz resolution and many more.

• SLMeter/RTA function
  • Recording of wav-files (24 bit, 48 kHz), a new wav-file is started after each hour (max. wav-file size 512 MB)
  • Percentile statistics for wide band, 1/1 and 1/3 octave spectrum: 1%, 5%, 10%, 50%, 90%, 95%, 99%
  • Sound Exposure Level LAE
  • 100 ms logging
  • Event-triggered audio and data recording
  • Time weighting: Impulse (LxI, LxIeq with x= A, C, Z)
  • True peak level in 1/1 and 1/3 octave resolution
  • Clock-impulse maximum level (TaktMax) and values as specified in DIN 45645-1
• FFT function
  • High-resolution Zoom-FFT with selectable frequency ranges and resolution up to 0.4 Hz in the range of 5 Hz to 20 kHz
• RT60 function
  • Reverberation time RT60 in 1/3 octave resolution
