Actual even worse than noise, it tends to get phantom readings in a cluttered environment (due to how sound wave can bounce around between objects in the environment). So a naïve, connecting the dots approach is not going to work well.
However, it is possible to use RANdom Smple Consensus (RANSAC) algorithm (http://en.wikipedia.org/wiki/RANSAC) to estimate lines from noisy measurement.
