Question about Local Sound and Sound in General

I have a looping sound in a prim that is on a thin strip of land (4m wide) and local sound is checked, but people can still hear it outside the parcel.

It's possible that the edge of the prim is outside the parcel, but the center of the prim and the prim allocation are within the parcel.

Anybody had problems like this with Local Sound?

Also, I'm confused about sound in general. The sound in question is not loud to me at all, even though it is at volume 1. Yes, I've read the Wiki, but my experience of sound doesn't seem to correlate well with what I've read in the Wiki.

The sound seems to fall off very rapidly with distance for me. Both my sound distance factor and rolloff factor sliders are in the middle.

Do different client configurations hear sound very differently? If so, how can you code your sounds so that everyone hears them the same. If you can't, then isn't sound kind of useless?

I guess the follow up question is:

What sound settings should I use so that my experience will be most like everyone else's?

Put your "rolloff factor" to about 15-25% and that'll greatly make sound distances more realistic.

Local sound prevent sound being played on other people land from being herd on your land. If your nabbers do not want to hear the sound, then they need to check off that option, not you. If you want to play a sound on your land, but not have it herd on your nabber's land. Then I would use llTriggerSoundLimited(string sound, float volume, vector tne, vector bsw) vector tne and bsw are used to define a 3d cube of space, witch the sound will be played in. Out side of that cube no sound will be herd.

I would quote wiki, but your probable better off reading the hole doc on trigger sound limited on wiki. http://secondlife.com/badgeo/wakka.php?wakka=llTriggerSoundLimited for such a small space. I would set a prim to phantom, get it's location, and the facts about it's size. With that info a script can calculate the tne and bsw of the square.

I know about this, of course. But I need it to loop.

ya timers :\
