General Analyzer Module
The general analyzer module allows for level versus time multi-channel sound pressure level measurements or level versus frequency analysis in 1/1 or 1/3 octave bands. This module can be used for product quality control and assurance using a reference curve where the low and high level criteria can be defined in each 1/1 or 1/3 octave band. Additional capability supports assignment of markers, statistic calculation and audio recording.
Building Acoustics Module
The building acoustics module is delivered with preset measurement setups for both national and international building acoustic standards such as the ASTM E90/E336 as well as the ISO-10140/16283 series. Simply select one of these and the entire system is ready to start the measurement procedure. This module can be used in laboratory environments for measurement of sound absorption or performance evaluation of building construction assemblies. STC and IIC ratings can be measured to meet Uniform Building Code (ICBO), International Building Code, Boca (Building Officials Code Administrators) code. Analysis and reports can be generated through direct measurements or by importing measurements into the module. The software allows users to import measurements made by other instruments as well.
