Larson Davis SoundTrack LxT (preconfigured kit KLxT-QPR)
The SoundTrack LxT® Sound Level Meter Kit KLxT-QPRwas specifically designed for gunfire testing, including suppressor and silencer testing. In product testing, the examiner is often tasked with determining whether the installation of a suppressor results in a “perceptible reduction” in the sound pressure level of a gunshot. The KLxT-QPR is an ideal tool for gathering, analyzing, and presenting detailed firearm noise data quickly, easily, and concisely. With a sleek ergonomic design, it is able to be held and operated with just one hand. See the following video for a demonstration of a firearms acoustic test.
With the included ¼” prepolarized pressure microphone, Model KLxT-QPR, is capable of reading the very high levels typically associated with gunfire testing. These readings can quickly be organized and stored on internal memory and exported to a PC for archiving and reporting. Reports generated include selectable noise parameters (peak, background level, max SPL, etc.) as well as calibration history of the instrument, important for courtroom presentations.
All sound level meter rentals include NIST-traceable calibration certificates. Rentals ship with a customer specific expected return date in mind. For example, if equipment is expected to be out for 5 months, the last calibration date will be within the past 7 months.
