Acoustic Testing
Acoustic measurements are used to quantify noise or sound power emitted from a product
Acoustic measurements go hand in hand with vibration measurements – and in many cases the the goal of vibration reduction is rooted in the need for a reduction in acoustic noise
Octave Measurements
Realtime Octave Measurements
Octave bank filters can be customized to fit your application; with support up to 20kHz on all input channels (ANSI S1.11 compatible)
Synthesized Octaves
Octave measurements can be synthesized from narrowband FFTs
In Parallel with Vibration Measurements
Create accurate synthesized octaves for acoustic measurements live during vibration measurements, with separate sample rates
Industry-Leading Hardware
High dynamic range
The 24 bit ADCs acheive over 140dB of dynamic range – making full use of sophisticated or ICP microphones
Quiet Operation
Abacus 901 is passively cooled and is completely solid state – it is completely silent and is perfect for acoustic measurements. The 906 supports a temporary quiet mode which disables its fans – it can be enabled to take acoustic measurements
High Channel Count
The 900 Series hardware works at low or high channel counts – allowing for the acquisition of hundreds of channels – alias free and synchronized to within 35ns
