Innovative design of acoustic treatment for air conditioning system

The objective of this study is to design a new acoustic treatment for air conditioning system, specifically jet pump noise source. The innovative design should have a large absorption band of frequencies (100 Hz - 5000 Hz) with a small thickness and mass. The absorption would be optimized with a special study of the noise source and a development of a specific modal detection (or antenna) adapted to the Topic Manager jet pump source will be set up. Please refer to the full and formal topic descriptions published in this call.
