Curious about why Acute Hearing 4 is the max

OK, using 0.2 instead of 0.3 and multiplying background noise penalties by 0.75 above 50 Db, here's another go.

Background Noise

description Decibels penalty
Rustling of leaves 20 +3
Quiet theatre, no talking 30 +2
Residential area at night 40 +1
Inside a quiet restaurant 50 +0
Inside an office or restaurant 60 -1 to -2
Busy traffic (at 5 yards) 70 -3
Vacuum cleaner, curbside of 80 -4 to -5
a busy street
Loud factory, heavy truck (1 yard) 90 -6
Jackhammer, disco* 100 -7 to -8
accelerating motorcycle 110 -9
(at 5 yards), chainsaw
Rock concert, 120 -10 to -11
jet takeoff at 100 yards

Loud noises (from High Tech):
Conversation, cocking or reloading 60 +2 (personally I would use +3 on this line only)
firearm, attaching bayonet
Bow, loud conversation 80 +6
Crossbow, shouting, car 90 +8
Air gun, firearm firing “silent” 100 +10
ammo, revving gas engine
Diesel engine, motorcycle, car horn 110 +12
Chainsaw, oxygen torch 120 +14
.22 LR, musket 130 +16
Light pistol, (.32 or .380 ACP), 140 +18
grenade launcher
Heavy pistol (9mm, .45 ACP), 150 +20
SMG, rifle, shotgun
Magnum rifle, HMG, stun grenade 160 +22

That seems to work better. It also fixes the sort of bug of a gun with a -5 silencer being quieter, as a practical matter, then a gun firing silent ammunition. (Assuming that's not intentional, of course.)

Anybody know some good penalties for having walls in the way? Perhaps -1 for a window (or a wall with a normal amount of windows), -2 for an ordinary TL 8 wood residential wall (and doors), and maybe -5? for a masonry or concrete wall.
