4. Mass-spring system
4.1 Principle
One-dimensional vibration systems are essential for describing certain acoustic phenomena to first order. Whether it's airborne noise or vibration transmission, the behavior is the same: an excitation on a facing decoupled from its support by a resilient (even air, for example) (figure 11 ).
Within certain limits, we can approximate the resilient layers to an elastic system with viscous damping. Without repeating the differential equations governing the motion of these masses coupled by a spring and damper,...
