To measure , calculate , display , print sound intensity sound pressure , sound power , three dimensional sound intensity spectrum , equal intensity contour are all deeply studied . a set of software using multiple document interface ( mdi ) running under microsoft windows platform is developed 本文就聲強、聲壓、三維聲強譜、等聲強線以及a計權、 1 / 3倍頻程的測量、計算、顯示、打印等進行了深入的研究,并編制了一整套運行于windows平臺的圖形化多文檔界面聲強測量分析軟件。

This paper researches on a novel method to measure three - dimensional sound intensity use for failure diagnosis of electro - hydraulic system and the fabrication of a miniature three - dimensional sound intensity probe by using two separate micro - machined pressure probes and one microphone frame 本文研究了聲強測量技術在汽車噪聲源識別中的應用。通過使用兩個微型雙麥克風和支撐它們的框架,我們設計了一個小型的聲強探測器,用它來實現對汽車噪聲源的聲強探測。

Besides that ray theory is helpful to calculate three - dimensional sound field , and the inversion of sound field could be finished quickly enough to realize the detection of ocean environment in wide area 特別是射線理論對解三維聲場尤為方便,它將有望實現三維聲場的快速計算和聲場的反演,達到海詳環境的監測目的。

When one tries the same trick with loudspeakers , though , the creation of three - dimensional sound runs into a serious problem called transaural acoustic cross talk 可是當我們試圖把這個伎倆用于喇叭上時,就會面臨漏音的大麻煩。
