Merriam-Webster: soothing, calming. Example: "Like all good listeners, he has a way of attending that is at once intense and assuasive: the supplicant feels both nakedly revealed and sheltered, somehow, from all possible judgment." (David Foster Wallace)
I am a good listener, but far more intense than assuasive.
You have the verb 'assuage' in your vocabulary; now add the adjective 'assuasive.'
