2nd

PFS StandardSilence  [two-actions] Spell 2

Illusion Manipulate Subtle 
Source Player Core pg. 357
Range touch; Targets 1 willing creature
Duration 1 minute
The target makes no sound, preventing creatures from noticing it using hearing alone. The target can't use sonic attacks, nor can it use auditory actions. This also prevents the target from casting spells due to the magical words involved in casting, with the exception of subtle spells.
Heightened (4th) The spell creates an aura in a 10-foot emanation around the touched creature, silencing all sound in or passing through it. While within the aura, creatures are subject to the same effects as the target. Depending upon the position of the effect, a creature might notice the lack of sound reaching it (blocking off the noise coming from a party, for example).
