the echoey church

[sitifan]

Ordinarily, the funeral director would have been there as well, but he had e-mailed earlier to say he was too ill to make it. Unnervingly, the vicar, who was only a few feet away from Andrew, had barely broken eye contact since he'd started the service. Andrew hadn't dealt with him before. He was boyish and spoke with a nervous tremor that was amplified unforgivingly by the echoey church.

What does "the echoey church" mean?

 

[Tarheel]

There is something of an echo in the building (because of its construction). Because of the way the building is constructed, there is an echo. (Maybe it's a faint one, but it's there.)

I think the fact that the tremor in his voice was "amplified unforgivingly" suggests that it's more than a faint echo.
