My brother was very calming after the race.

I sang to the baby in a calming voice.

Traffic calming refers to slowing down speeders. One method commonly used is posting the driver's speed as detected by radar often closely juxtaposed to a sign stating the legal limit. Speed bumps have become ubiquitous especially near schools. A roundabout is an elegant solution to 'naturally' slow down speeders. Of course, the presence of a visible police care is probably the most effective method.

Calming and unnerving are antonyms as they mean opposite things.

A calming place is anywhere with an ocean, soothing sounds, a spa, anything quiet.
