Electro Acoustical Measurements and Developments

You want to set up new loudspeakers in a studio, have developed the prototype for a new microphone, or require special data for a piece of equipment which are not specified in the manufacturer's data sheet? IRT can assist you in these cases and many others by performing measurements to define sensitivity levels and directivity indices, impulse responses, directivity patterns, non-linear distortion, or the background noise of electroacoustic transducers.

On the basis of our readings, we can then provide precise answers to your questions and suggestions for enhancements, if necessary. IRT specialists can help you realise your ideas and develop new microphones or loudspeaker systems. We also gladly assist you with the optimisation of acoustic accessories such as microphone windshields.

IRT has an outstanding spectrum of devices at its disposal as well as all the necessary measuring facilities (e.g. anechoic chamber, reverberation chamber).

IRT developed KEM, a cardioid microphone which is truly innovational and features an omnidirectional directivity pattern comparable to that of a loudspeaker line. By carefully coordinating the interconnection of individual microphones along a common axis, a configuration can be created which offers advantageous angular distribution of acoustic sensitivity for a number of applications (e.g. the positioning of microphones on people for broadcast purposes or for music/theatre performances).

IRT’s KEM even enjoys great success in Germany’s Bundestag – at the speaker’s lectern on the floor of Berlin’s Reichstag.
