Quickly identify noise sources
Accurately determine the sound power radiating from noise sources
Acquire measurements in acoustically noisy environments (in-situ), eliminating the need for costly acoustic chambers.
Check for ISO standards compliance in seconds

STARAcoustics organizes data by project: All test parameters related to the instrument, microphone, and environmental conditions are conveniently located in a single Project Slate. New and occasional users can guide themselves step-by-step through the acoustic intensity process by referring to the Show Assistant, a process-oriented task list.

The STARAcoustics program has a state-of-the-art, interactive measurement display designed expressly for narrow band and octave band acoustic measurements, including real, complex, and bi-polar data. You can view individual measurements, or, because the display accommodates an unlimited number of measurement windows, view entire data sets to spot trends or anomalies. A comprehensive set of display features-cursors, zooming, grids, and scaling-enables you to focus on the measurements of interest.

The STARAcoustics program performs a very wide variety of functions on narrowband and octave-band intensity or sound pressure level (SPL) data. Narrowband cross spectra and auto power data is automatically converted to Intensity and Sound Pressure datatypes respectively, synthesize data into 1/1 octave, 1 /3 octave, or user-defined bands. Weighting (A, B, and C) and correction (amplitude and phase) are easily applied. Critical data evaluation functions such as Pressure-Intensity(PI) index, Residual PI, and Dynamic Capability index are automatically computed as part of the Plot tab Data Types.

To check overall measurement quality, the STARAcoustics Measurement display can be configured to overlay the Dynamic Capability Index of the measurement system and the PI Index of selected measurements. You can easily scroll through the PI Indexes for each measurement location and to visually inspect measurements to confirm that they are within the acceptable limits of the dynamic capability of the measurement system.

CATSAcoustics/STARAcoustics graphs data in two or three dimensions to help you identify the location of noise sources. Contour maps handle both uniform and non-uniform test grids that match the geometry of a planar test surface. 3D vector displays enable you to examine the characteristics of sound fields, particularly around non-uniform structures. The vectors provide insight into noise source locations, strength of intensity, and propagation direction.

STARAcoustics uses the areas associated with each measurement location to compute overall sound power. You can view computed power levels in either tabular or chart formats, in watts, decibels or percent of total power, and computed by point, component, or overall level. You can rank data to quickly identify significant sound power contributors or choose a single command to compute the composite sound power spectrum from a set of measurements.
