DATS Acoustic Analysis Suite

The 1/N Octave filters can be used with either time signals or narrow band spectral data.

The Sound Power Analysis scripted measurement procedure allows the measurement of sound power using either sound intensity probes or microphones according to the international standards ISO3744, ISO3745 and ISO9614-1.

The Sound Level Meter module provides a number of analyses that mimic the operation of a simple sound level meter.

The Transmission Loss modules are automated measurement and analysis procedures for determining the effectiveness of either panels for room acoustics or pipes for exhaust mufflers.

The Room Acoustics Reverberation Time T60 and Total Absorption modules use the noise source switch-off method. The T60 determination is based on a practical measurement with a decay in the room of less than 60dB.

The Two-Microphone Impedance Measurement Tube, (B&K Type 4206), is a completely scripted measurement procedure for guiding the user in making an accurate measurement of the acoustic properties of small material samples, it complies with ISO10534 and ANSI E1050.
