Is there a difference in what you hear from the ground due to cloud over and denseness of cloud?

Eg. When a plane goes over do you hear a different level of sound depending on the denseness of the cloud.Is there a difference in what you hear from the ground due to cloud over and denseness of cloud?
Yes you do. In cloudless air, sound attenuation increases with relative humidity up to a peak at 17% (1 kHz, 0 C, SLP) and then decreases as RH increases to 100%. In clouds, however, attenuation is greater than in cloud-free air. See the refs.
