【讨论】这两句话的意思

Forecasters say the market explosion will really unfold after 2009.

预测家们预言该市场会在2009年后出现真正的火爆

这段话的意思好象是说以硅为主要材料的微机电系统将有很大的发展前景，预计2009年之后将会出现火爆场面。前面那句话直译还真不好译。

rumbling : may mean 闲言碎语 (or 八卦消息)

感觉that rumbling跟前面有句话有关，但是楼主没写出来。

搜索了下，前面好象没有什么话了，内容大概如下：
Sound Check: Silicon MEMS Microphones Ready To Make Lots Of Noise

Companies in this small arena are mapping strategies for a much bigger commodity market beyond 2010, aiming to replace electret condenser microphones and address new application requirements.

What’s that rumbling? It’s the ever-loudening boom expected to stand the silicon microelectromechanical systems (MEMS) microphone market on its collective ears. Forecasters say the market explosion will really unfold after 2009.
Two years ago, only three or four dominant silicon MEMS microphone manufacturers existed. Knowles Acoustics had the lion’s share, followed by Akustica, Pulse Engineering’s Sonion MEMS Division, and Infineon Technologies. Now the list includes at least a dozen others (see “Representative Silicon MEMS Microphones” at www.electronicdesign.com, ED Online 20667).

这是一种科技消息的报道方式。非常的口语化。是否翻译为“惊爆消息”：

似乎是讲关于MEMS方面的报道非常热闹,但on its collective ears?

前面有个stand, stand on the ears,使耳朵立起来，是否是引人注意的意思，collective这里不知道是何意，收集信息的耳朵？？？很多耳朵？？？众人耳朵？？
