资源简介:
The supplementary material contains sound examples from the Klima|Anlage ("Climate Control Unit") performing climate data from 1950 to 2100 for various regions. The overall soundscape of the Klima|Anlage has distinct sounds that can be followed over time and compared for different regions (one at a time). The eleven-year solar cycle leads to a slowly pulsating harmonic spectrum on a tetrachord instrument, with a period of roughly one minute; it is slowly detuned over time according to radiation balance data. Thunder sheets follow shorter, yearly cycles of the air temperature, and oscillate between a low grumbling and high intensity rattling. The noise of two marble plates placed on a record player mimics large wind intensities in the higher atmosphere, changing from left to right in the stereo panorama as the wind direction reverses. Furthermore, resonant water drops vary in their rate from random single drops to heavy rain sound. Finally, an electronic „beep“ sound is used to map the global greenhouse gas emission concentrations and provide orientation over time. The beeping rate increases with rising concentrations. <br> <br> Tibet: <br> Northern Europe: <br> Amazon: <br> Australia: <br> Greenland: <br> Sahara: <br> Indonesia: <br> Western North America: <br> South Africa: <br> East Canada: <br> Central Asia: <br> Middle Europe:

本补充材料包含来自气候控制单元(Klima|Anlage)的声效示例,该单元基于1950年至2100年的气候数据,为全球多个区域生成对应声景。该气候控制单元的整体声景包含清晰可辨的声效元素,可随时间追踪其演化过程,也可针对不同区域逐一开展对比分析。十一年太阳活动周期会通过四弦乐器(tetrachord instrument)生成缓慢脉动的谐波频谱,其周期约为一分钟;该频谱会依据辐射平衡数据随时间缓慢失谐。雷鸣声效遵循更短的年度气温周期,在低沉轰鸣与高强度震颤之间往复变化。将两块大理石板置于唱片机上产生的噪音,可模拟高空强风效果,并随风向反转在立体声场(stereo panorama)中从左至右动态变化。此外,共振水滴的发声频率会随机变化,覆盖从单一水滴滴落声至滂沱大雨的全范围音效。最后,电子"哔哔"声被用于映射全球温室气体排放浓度,并随时间提供方位指引;哔声频率会随浓度升高而加快。 西藏: 北欧: 亚马逊流域: 澳大利亚: 格陵兰: 撒哈拉沙漠: 印度尼西亚: 北美西部: 南非: 加拿大东部: 中亚: 中欧:
