项目摘要
B. Pilsudski's sixty-five wax cylinders were brought to the Research Institute of Applied Electricity, Hokkaido University, for reproduction and investigation of the sound recorded on them. Using the Edison-type phonograph, its stylus gives such a heavy pressure of approximately 20 g to the grooves of the wax cylinder in the reproduction process that there is definitely a grest risk of damaging the wax cylinder. This is a problem because not only the sounds recorded on the wax cylinder but also the cylinder itself is part of our cultural inheritance. So a method using a very light pressure stylus was developed as a reproduction system of the sound from wax cylinders. However, there were twenty-four more cylinders that have not yet been reproduced; the stylus method cannot be used because the cylinders are cracked or in pieces. These broken wax cylinders were repaired. Since the valuable sounds of the Ainu talk and songs lost so long ago seem to be recroded on these cylinders, reproduction is most important. To reproduce the sounds from these repaired cylinders, the laser-beam reflection method which is noncontacting and nondestructive was developed.The present research was done by following the four steps: (1) Cleaning and replication of the wax cylinders, (2) Sound reproduction using the tylus method and the laser-beam reflection method which were newly developed, (3) Noise reduction for two different spike-like noise and random noise.
B。毕苏斯基的65个蜡筒被带到了北海道大学应用电学研究所,用于复制和研究其上记录的声音。使用爱迪生型留声机,其唱针在复制过程中对蜡筒的凹槽施加约20 g的重压,因此肯定存在损坏蜡筒的极大风险。这是一个问题,因为不仅记录在蜡筒上的声音,而且蜡筒本身也是我们文化遗产的一部分。因此,开发了一种使用非常轻的压力笔的方法,作为蜡筒声音的再现系统。然而,还有24个圆柱体尚未复制;由于圆柱体破裂或破碎,无法使用触针方法。这些破碎的蜡筒被修复了。由于阿伊努人的谈话和歌曲的宝贵的声音失去了这么久以前似乎是重新录制在这些圆筒,复制是最重要的。为了再现这些修复后的圆柱体的声音,发展了非接触、非破坏性的激光束反射法。(1)蜡筒的清洁和复制,(2)使用新开发的胎块法和激光束反射法进行声音复制,(3)对两种不同的尖峰噪声和随机噪声进行降噪。
