中文摘要:
      本文介绍了4种高声强声源:(1)单孔旋转阀;(2)带中心杆的哈特曼发声器阵;(3)喷流点声源;(4)喷流反馈旋转发声器。本文还给出这4种声源的用途,即分别应用于:(1)流动管道中有限振辐波的传播研究;(2)进气道吸声内衬的声阻抗测量技术;(3)风洞声学环境的研究;(4)利用高强度声能来清灰除尘
英文摘要:
      In this paper, in accordance with the requirements of speech study, the authors have developed a speech analysis, modifying and synthesis system, which integrates speech sampling, analysis, synthesis, revising, comparison, playing and modifying into one, and modifies speech parameters by parameter revising middle value smoothing Hanning window filtering mouse lining and value modifying. The ystem can shorten the time for speech analysis and synthesis promote efficiency, inquire into the quality of speech analysis and synthesis. It is very useful in speech study. The paper presents the system in three a spects:architecture, function and application.
