Unable to hear rain between level 92 and 88 (Only when moving from a higher elevation)

I had just gone up the top of a mountain in the extreme hills biome when it started to snow. As I moved down the mountain the snow stopped and the rain started. However, for those four blocks which were showing rain particles, I was unable to hear the rain. However, upon walking back up the hill I can hear it fine. These extreme hills were generated in 1.4.x.
