Our reading
An editorial interpretation.
The speaker admits a dislike of sounds in general, and a stronger one when a sound has no reason to be there. Unexplained noise is what unsettles them. The plain, grumbling phrasing suggests a wary person who expects silence and distrusts anything that breaks it.
