Noise and vibration analysis

ICR has always insisted on the importance of including real testing in its analyses. The main reason is that experimentation enables us to capture the reality of direct knowledge of the problems being dealt with, whilst theory makes it possible to understand the reality in question and to establish effective alterations.

However, at times this more theoretical part has proven insufficient, as ICR has been implementing its own methods for years and has helped develop certain internationally recognised theories such as APTA (Advanced Transmission Path Analysis) method for the analysis of noise transmission paths, and the inversion model.

At the same time, and in order to put the more experimental part into practice, the company has been upgrading its equipment, consisting of a total of 48 simultaneous noise and vibration analysis measurement channels. They all analyse the signal as a function of frequency in real time, and are capable of analysing spectra, transfer functions, coherence... The simultaneous control of this large amount of measurement points enables us to conduct the efficient testing needed to diagnose acoustic solutions for real vibro-acoustic problems.

 

ICR is an Acoustic Engineering resolving problems of noise and vibrations. ICR works for the railway, car, industry, construction and environmental sectors. The company researches (R+D) new methods to solve vibroacous-tic problems. ICR also designs software for quality control and transmis-sion loss and teaches acoustics to private companies and official colleges.
