QualidB a new approach of acoustic measurement QualidB is a signal-processing platform which has been developed to improve the results with repetitive tests and to overcome the needs concerning acoustic measurements in the automobive world.
Used in the past in the diagnosis and cure of defects observed on prototypes, systematic measurement are set up carry out validations, function by function. It is in this context that MicrodB developed the signal-processing platform QualidB which is perfectly adapted to processing repetitive tests.
Productivity, easier use and data fluidity
A database structure and some judicious choices of I.T. have allowed us to make a significant saving in processing time. The user interface, developed in C++ allows for intuitive use. At least, MicrodB enables one to exchange data between systems, in particular.
Simple footbridges of use make it possible to exchange data with LMS platform. The QualidB software controls the Oros hardware.
Application
The QualidB software makes it possible to reach various applications: Usual signal-processing tools, measurements with impedance tubes, measurements in small cabins. jury testing software. quantification of the acoustic quality. localisation of the sound sources with the nearfiled focalisation.
