It is a bit of a challenge to get accurate distance readings with sonic sensors. Sonic sensors report stable readings when faced a flat surface and there is no obstacles between sonic sensors and a target. The following image shows distance readings to a wall. Both sensors read 27" distance:

Once I turn sensors away from the wall I get:
