Acoustic Control System

The m+p VibControl acoustic control system provides features such as support for up to 40 microphones for control and/or measurement (more on request), continuous time domain octave analysis in 1/3 and 1/1 octave bands, a control bandwidth up to 10 kHz with multi-horn control, equalizer tool, calibration tool, automatic microphone drop-out detection and exclusion from control, extensive octave band and OASPL alarm and abort checks for safe testing as well as comprehensive post-test analysis and reporting functions in 2D and 3D.

The user interface of the acoustic control system has the same look and feel as the interface of the m+p VibControl vibration controllers for set-up, test run and post-test analysis. Supporting the same Ethernet-based m+p VibRunner hardware, m+p VibControl for acoustic control can be configured as a vibration control system for shaker testing by simply adding software modules.

Key Features

Acoustic Control System for Reverberation Chambers
