To grasp dwelling distribution of birds living in water sites and investigate their acoustic tastes by means of acoustical engineering, basic researches were carried out and the following main results are obtained :(1) From automatic recording and analysis of acoustical signals, up to ultrasonic range, radiated from birds living in water sites, it is made clear that most of the birds emit signals in ultrasonic range as well as audio one.(2) Recorded audio signals of bird songs amount to the quantity of about 20 DAT tapes, each of which being for 2 hours.(3) On-line signal processing system of highly flexible and high speed was constructed by connecting a newly introduced high speed work station with the existing system in our institute by way of computer networks.(4) 2D and 3D spectral pattern information obtained from the 2nd and 3rd order spectral and speech analyzes of measured bird songs was compressed as vectors of simple forms, and the resultant 14 kinds of vectors were discriminated by discriminant analysis and neural network. The latter provides the more correct discrimination rates than the former.(5) Investigation of acoustic tastes of the birds through radiation of artificial signals shows that birds seem to be more sensitive to burst signals than to stationary ones.

为了掌握居住在水位地点的鸟类的居住分布，并通过声学工程研究了它们的声学品味，进行了基础研究，并获得了以下主要结果：（1）从自动记录和声学信号分析中，到超声范围从居住在水地点的鸟类中散发出来，很明显，大多数鸟类在超声波范围内发出的信号以及音频一号。（2）记录的鸟类歌曲的音频信号总计约为20个dat录像带的数量（3）通过计算机网络将新引入的高速工作站与现有系统连接到现有系统的在线信号处理系统是通过计算机网络连接到现有系统的。（4）2D和从第二和第三阶光谱获得的3D光谱模式信息和测量鸟歌曲的语音分析被压缩为简单形式的向量，由此产生的14种矢量被判别分析和神经网络歧视。后者提供了比前者更正确的歧视率。（5）通过人造信号的辐射来调查鸟类的声学品味，表明鸟类似乎对爆发信号比对固定信号更敏感。
