LXT-OB3 (1/1 and 1/3 Oct Analysis)
Larson Davis Lxt Sound Level Meter; 1/3 Oct Frequency Analysis Provides real-time 1/1 and 1/3 Octave frequency analysis, that is useful in tonality assessment, selection of hearing protection, and qualifying of ventilation system.

Wide frequency ranges are provided:
- 1/1 Oct : 8 Hz to 16kHz
- 1/3 Oct : 6.3 Hz to 20kHz

Leq, Lmax and Lmin are measured with A, C or Z frequency weighting.

Remark : 1/1 Oct options (LXT-OB1) is available if only 1/1 Oct Analysis is needed (e.g. for selection of hearing protection)
LXT-ENV (Measurement History)
Larson Davis Lxt Sound Level Meter, Measurement History Logging Measurement History is used to perform a sequence of measurements using the same setup, either manually or automatically, at time interval from 1 min to 24 hours. All parameters are logged including spectra and statistics (Ln). The function is useful for environmental Base Line Monitoring study and report.

The Interval Time Sync feature ensures that all measurement records are properly aligned in time for easy reporting. For example, if the measurement time is five minutes, and the measurement begins at 08:14:00 (h:m:s format), the first measurement will be cut short such that the subsequent measurements will begin at 08:15, 08:20, 08:25, etc.

Different Smart Run Control Modes are very useful for monitoring. For instance, Daily Timer Mode can start automatically and collect data at mid-night from 1am to 3am for the coming 1 week. Another example is Continous Mode. SLM resumes measurement automatically when the power recovers after failture.
LXT-LOG (Time History)
Larson Davis LxT Sound Level Meter Analyzer; Time History Logging In Time History mode, SoundTrack LxT can automatically log up to 16 acoustic and non-acoustic parameters including spectra, at time intervals from 1 second to 24 hours.

10 markers are available for annotation of time history for different sound sources (truck, aircraft...etc)

Remark : for precise timing of noise event, logging down to 100ms can be achieved by LXT-HSLOG option.
