Larson Davis LxT Sound Level Meter Overview

The SoundTrack LxT® Sound Level Meter was developed to meet the unique needs of those involved in workplace noise exposure assessment, plant noise surveys and noise ordinance enforcement. With a sleek ergonomic design, it is able to be held and operated with just one hand.  The LxT is the perfect tool for gathering, analyzing and presenting detailed noise environment data quickly and easily. New and better ways to organize your sampling methodology and annotate noise survey data save time and provide concise results at a price that won't consume your entire instrumentation budget.
