Directional Source
BAS003
The BAS003 Source is designed to generate homogeneous sound fields using random noise in compliance with the following standards: Building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-3, ASTM E90, ISO 140-5, ASTM E966). The BAS003 is typically used to generate a noise in a free-field for the evaluation of the transmission loss index of a façade. The available high-efficiency power amplifier, BAS002, is light and can be remotely controlled for easy use in the field.

Human Vibration Management Software
HVManager
HVManager is a Risk Assessment and Recordkeeping software tool for reporting Vibration measurements and predicting Personal Exposure Levels. It provides reports of vibration measurement data from hand-arm and whole-body measurements acquired from the Larson Davis HVM100 Human Vibration Meter and produces vibration database records by tool type and serial number. HVManager also compiles cumulative predicted vibration exposure levels from any combination of tools and task durations taken from the measurement database.

Omnidirectional Source
BAS001
The BAS001 Source is designed to generate omnidirectional sound fields for making standard compliant measurements including: reverberation time (ISO 3382, ASTM E2235), building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-4 ISO 140-3, ASTM E336, ASTM E90, DIN 55 210). The BAS001 is typically used to saturate a room with a uniform acoustic field. The available high-efficiency power amplifier has no fan for cooling, allowing measurements in quiet environments, like those in reverberation time applications.

Sound Level Meters
LXT1-QPR
Quantitative measurements of sound pressure levels generated by firearms with & without suppression devices and silencers.Many firearm examiners are tasked with determining whether installation of a suppressor or silencer on a firearm results in a “perceptible” reduction of the sound pressure level of a gun. The Larson Davis SoundTrack LxT® provides this functionality utilizing an easy-to-use handheld platform.
