abat-voix

In this context it is also known as an abat-voix.

Decorated with scenes from the passion of Jesus and a baroque abat-voix from 1723, the pulpit now creates the effect of a unit.

In religious art and architecture, an abat-voix (from French abat-voix, or sounding-board) is a sort of canopy which is placed above a pulpit and which serves the purpose of reflecting the preacher's voice toward the audience.
