This isn't about how far a human could hear. I guess we could start arguing about how good zombies' senses are, but I decided to just scale the numbers according to the values for the loudest weapons as they are in the game.

I don't remember where I got the 49db, some random website, but Wikipedia says the Welrod pistol is 75db, and that's supposed to be one of the quietest weapons ever. A converted weapon, like the MP5SD, or a screw on silencer, like the M9SD, would have to be louder than that, but I can't find any exact numbers. Movies would have you believe that silencers turn a gunshot into a whisper, but truth is, the sound is still pretty loud. The idea is more to make it sound like something other than a gunshot. And if you were using it in a noisy environment, like a city, 75db would blend in to the ambient noise. No one would think twice about hearing a "pop" sound over the din. Listen to this video, you can still hear the silenced shots echoing.

I fixed the ratios using logarithms. This site has a chart showing difference in "loudness", but it admits that this is a tricky and subjective thing to measure. http://www.gcaudio.com/resources/howtos/voltageloudness.html

Louder sounds carry logarithmically more energy, but doesn't the sound level also drop off logarithmically? So wouldn't the two cancel each other out? Yeah, my point was more that the current system is ridiculous.

Sources: http://www.freeheari...firenoise.shtml http://dayzdb.com/database/weapons http://world.guns.ru/ I used some estimation for weapons that I couldn't find exact figures, like the .50cal sniper rifles, I just used the value from a M2HB. The Winchester is a guess on my part, I couldn't find decibel values for any black powder weapon, just people saying that it is quieter than a modern weapon, but still loud enough to need hearing protection (>140db).

I always knew my Lee-Enfield was loud in game, but I was shocked to find out that it was three times louder than an M16 or AK. After doing some research and math, I came up with these numbers for realistic distances at which various weapons would attract zombies. The db values are taken from varius sources, and some are my estimates. If you can find better data, please comment and I'll update. Edit: forgot that decibels are logarithmic, corrected.

There's no way a zed could immediately lock on to someone half a click away just because they fired a .50cal.
