source of ambient noise 中文意思是什麼
source of ambient noise
解釋
環境噪聲源-
The coherence analysis of the sound field using prssure and particle velocity combined processing was discussed. a new kind of combined sensor was used to gather the information of the sound field. the main idea of this paper is to seperate ambient noise field , and the characteristics of it can be further studied. the coherence of a point source sound field was also analyzed to verify the validity of the approach
聲場聲壓與振速的相干性是聲壓、振速信息聯合處理的重要物理基礎之一,本文對其進行了初步的分析.在新型組合傳感器湖試的基礎上,把環境噪聲場分解為不相干的各向同性分量和相干的各向異性分量,初步分析環境噪聲場的構成;同時對點源聲場的相干性也進行了驗證性的分析 -
