The reason cell phone speakers often sound "shrill" is that manufacturers love to overboost the 3k-8k range in an attempt to create a richer tone for media playback, but that's certainly not the frequency that's going to be getting past walls. Meanwhile the lower frequencies on these cell phone speakers are absolutely terrible, often -20 or even -30dB off peak by 500Mhz.

Of course, if the walls are thin enough, anything's going to get through.
I don't think that the physics of sound is what's really at issue here.

I agree. Why aren't headphones an indispensable part of ones business travel equipment, right along with the power cord for your laptop? And we've completely overlooked the privacy aspect of discussing business issues where one can be overheard.
