Considerable doubt is cast on the validity of past satellite measurements of micrometeoroid fluxes in which piezoelectric microphones have been used as detectors. Data have been obtained from satellite and laboratory experiments which show that the microphone crystals emit noise when subject to slowly varying temperatures. The rate of noise is consistent with past flight data which have previously been interpreted on the basis of micrometeoroid impacts. These measurements have given rise to the theory that the earth is surrounded by a cloud of dust, although no satisfactory mechanism has yet been found to explain this apparent phenomenon. On the basis of the results reported here, it now appears that whether or not a concentration of dust exists in the vicinity of the earth, the data from satellite microphone measurements should not be used to support such a hypothesis.
过去使用压电麦克风作为探测器的微流星体通量卫星测量的有效性受到了相当大的质疑。从卫星和实验室实验中获得的数据表明,当麦克风晶体受到缓慢变化的温度时,晶体就会发出噪声。噪声的速率与过去的飞行数据一致,这些数据以前是基于微流星体撞击的基础上进行解释的。这些测量结果产生了一种理论,即地球周围环绕着一团尘埃,尽管还没有找到令人满意的机制来解释这一明显的现象。根据这里报告的结果,现在看来,无论地球附近是否存在尘埃集中的情况,都不应该使用卫星麦克风测量数据来支持这样的假设。
