What is Sound Control in Payload Fairings about?

This dissertation investigates a new passive method to reduce sound transmission into payload fairings using distributed vibration absorbers (DVA) and Helmholtz resonators (HR). A coupled structural-acoustic model is developed, demonstrating noise reduction of up to 9dB in specific frequency ranges, validated through outdoor experiments on a composite cylinder. Additionally, an adaptive HR is introduced, capable of adjusting to varying acoustic conditions, achieving broadband noise reductions similar to opt
