Summary,This monograph has been a presentation of a new experimental technique for the spatial characterisation of complex, random sound fields. Such fields are encountered, for example, in the study of acoustic fields in ducts, enclosures and in the ocean, and in many other contexts.fluffy 发表于 2025-3-24 15:21:12
