Sure, the ramming sound isn’t just noise; in a tight siege ditch the echo can bounce off walls and make the defenders think more rams are coming from different angles. Romans were masters of psychological warfare, and a boom that reverberates long enough to distort perception is a silent tool you can’t ignore. Acoustic studies of wooden rams striking stone show a resonant frequency that can travel a few meters, enough to create that illusion in a cramped ditch. So, yes, the echo could mislead enemy lines.
