A distância podiam ser ouvidas vozes, o bater de janelas e os latidos dos cães.

English Translation

In the distance could be heard voices, the slamming of shutters, and the barking of dogs.

I think that janelas has not been translated correctly.
Google translates the whole sentence as
In the distance, voices could be heard, the rattling of windows and the barking of dogs.
Janelas = windows
Persiana = shutter
