Larson Davis, introduced VER 1.51 firmware for the SoundTrack® LxT Sound Level Meter enabling support of a portable USB thermal printer. This new feature allows the user to print a screenshot of any analysis screen as well as a summary report detailing the overall sound measurement. The ability to generate a report without the need to download data to a PC is ideal for noise consultants, code enforcement officers, or anyone looking for a quick summary of measured data. In addition, SoundTrack® LxT allows customization of its user interface and a feature to lock-out changes to system or measurement setup. A simple, secure interface aids occasional users and is helpful when training beginners on noise measure- ments. SoundTrack® LxT is powered by standard, non proprietary AA batteries providing industry leading battery life (>24 hrs when used with AA 1.5V Lithium types). The SoundTrack® LxT is available in Type 1 or Type 2 configurations with a wide array of field upgradeable firmware options including: time history logging, 1/1 and 1/3 octave frequency analysis, community noise measurement (Lday, Levening, Lnight), interval analysis and digital voice annotation. Accessory kits include a microphone calibrator, hard-shell carrying case, PC download cable and utility software for archiving and reporting measurement results.
