Zombie hearing through walls(too sensitive)...What can be done?

[daliputka 7]

Hey,

I've noticed that a lot of times zombies can hear me through walls like there was no wall there. I'm pretty sure they can't see me, but it seems being inside a building does little/nothing for sound diminishing.

I didn't want to open this as a bug as it appears that bug admins are either overloaded or not existant currently and I also didn't know if this was even a bug. What are other people's thoughts? Can anything be done?

-D
