Noise treatment of turbomachinery

Details

Published: 12 February 2026

The transfer of energy between a rotating part (a rotor) and a fluid (a liquid in the case of a pump, air in the case of a compressor, another gas in the case of a combustion turbine), which forms the basis of turbomachinery operation, is accompanied by very significant noise emissions, characterized by a very high sound power level over a wide frequency range. Noise treatment of turbomachinery is necessary for various reasons:

• from the perspective of the health of employees (and also of...

Noise abatement in a production facility

Details

Published: 02 January 2026

Noise abatement in a production facility is necessary for several reasons:

• as regards the health and well-being of employees, which must be preserved by offering them sufficiently good working conditions, if only to avoid the decline in the quality of production, absenteeism, hearing injuries and accidents possibly resulting from excessive fatigue or stress, or even from the failure to perceive audible warning signals. Prolonged use of noise-canceling headphones - which do not always offer...

Design and construction of a semi-anechoic room for acoustics R&D works

Details

Published: 03 December 2025

ITS will participate in the design and construction of an anechoic room for acoustics R&D works near Paris (Île-de-France region, France). The project will provide technicians and engineers with a space enabling high-precision measurements of sound pressure and possibly sound intensity levels inside and outside automobiles to improve acoustic comfort for drivers and passengers during their journeys. With regard to electric vehicles, the aim is obviously not to address the noise emissions of...
