Sound Level Meter & Real-time Analyzer
824
The Larson Davis System 824 combines advanced sound level meter and real-time analyzer capabilities into a rugged, user-friendly, ergonomic package. The base unit is an Integrating Sound Level Meter (ISM) that meets Type 1 Standards and offers simultaneous measurement of sound pressure levels using fast, slow, and impulse detectors, for A, C, and flat frequency weightings. This feature, termed ANY LEVEL™ measures 48 sound pressure parameters at once with a linear, 105 dB range. With firmware enhancements, the base unit expands as needed to accommodate multiple data processing requirements

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.

Noise Monitoring Kit
LxT NMS SoundExpert
In addition to the SoundExpert LxT meter, this kit includes the EPS042 protection case and D-cell battery pack, the EPS2116 microphone protection shroud, and EXC010 10 ft. cable. Using D-cell alkaline batteries, allows the noise monitor to be smaller and lighter; avoid the expense of shipping heavy lead acid batteries and the hassle of recharging. You can transport it easily to your site, deploy it, measure data, retrieve your system, download the data, and issue your report.

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.
