Over the years, a wide variety of sound level and octave band instruments from Commissioner for Industrial Hygiene and Safety to monitor the noise were used in the workplace. Many of these devices require quite a long training period, which is why Larson Davis has placed on ease of use in the development of the sound level meter great importance.

The sound level meter SoundTrack LxT® was developed specifically for the special needs of those who deal with workplace noise measurements. The unit meets fully the IEC and ANSI standards for sound level meter class 1 and 2. Furthermore, are lxd files fully compatible with the measurement strategies according to ISO 9612: 2009 for work-related measurements.

Starting with its ergonomic design to its clear presentation of the data SoundTrack LxT® is the perfect device for fast, easy and accurate collection, analysis and presentation of environmental noise data. New and better ways to organize and commenting the acquired noise data save time and deliver better results.
