Description
Summary:A new approach to solving the problem of reducing the noise produced by vibrating elastic structures is proposed. It is based on minimizing the flow of acoustic energy between subsystems by means of local structural changes. The author describes the theoretical grounding of this approach and presents the results from experiments that prove its relatively high efficiency (12–15 dB). The approach is useful in cases that require noise reduction without increasing the mass of a structure.
