Let's make apprentice created enchantments

Trinket of Imposed Civility
ReIm 15
R:Touch, D: Sun, T: Room
This lesser enchanted device is a down feather encased in a drop of somewhat transparent glass. When activated, it prevents sound in the room where it was activated from rising above the level of normal conversation until the next sunrise or sunset. This device was first developed in a covenant where there were simultaneously three apprentices beneath the age of 11, who often became too loud for the comfort of their paters/maters when in one another's company. the laboratory text uses a +3 material bonus from down.
(Base 2, +1 touch, +2 sun, +2 room)

The rego imaginem guidelines don't address controling volume.... but they should.

Edit: I see Aurelentus from Magi of Hermes did this with Perdo at base 3. I'm judging that putting a cap on volume is equivelent to moving the sounds 5 paces away (out of the room), is that too low?
