Sound Level Meter
831-LOWN
-
Easily make low noise measurements to 6.5 dB A-weighted using the Model 831-LOWN sound level meter paired with the 378A04 low noise microphone and preamplifier. Due to the innovative design of the 378A04 which uses a prepolarized microphone and ICP (constant current) interface, the combination produces a highly portable system that is battery powered and intuitive to use for measuring low noise levels.

Impulsive Sound Source
BAS006
-
The BAS006 is an innovative device used to create impulsive noise that includes low frequency energy and avoids problems like secondary bounce. These characteristics make it a great choice for quickly measuring reverberation time when the complexity and weight of a speaker and amplifier is not needed.

Headphone Test Fixture
AEC206
-
The Larson Davis Model AEC206 Binaural Test Fixture is the tool for testing supra-aural, circumaural, supra-concha, intraconcha, and insert-type headphones. Preassembled with IEC 60318-4 (711) occluded-ear simulators and TEDS compatible preamplifiers that provide electronic calibration information, the Model AEC206 is user-friendly and easy to learn. Additionally, calibration is a simple process—a custom adapter is included for the Model CAL250 acoustic calibrator or similar device.

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.

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

Human Vibration Monitor
HVM200
-
The HVM200 is a small rugged vibration meter with built in Wi-Fi that can be used to measure hand-arm, whole body and general vibration. It includes the metrics and frequency weightings needed to measure human vibration. This 3 channel meter meets the requirements of ISO 8041:2005 and it is designed to measure per ISO 2631-1, 2 & 5 and ISO 5349 in support of the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) and the directive 2002/44/EC. This makes the HVM200 an ideal choice for an instrument used to demonstrate compliance with human vibration requirements and regulations worldwide.
