Many Churches are moving to outdoor worship as a way of maintaining social distance protocols. If you have worship on the Church lawn, then people can space out as they feel comfortable.

The challenge is to have a PA system that handles this. Think of an outdoor concert. It has to be loud enough to drown out the noise of traffic going by. But it also has to be soft enough not to offend anyone. Perhaps you need multiple speakers set up so that everyone can hear clearly without being too loud.
