The yellow house on the corner (730 Mt Auburn) has multiple Yard Sentinel Ultrasonic Pest Repellent devices in their yard, which emit an ear-piercingly high-pitched noise when the motion sensor is tripped by cars and pedestrians. In effect, this noise is emitted the entire time when walking on the sidewalk along the property line (i.e. from one edge of the white fence to the other). The sound might be too high of a frequency for mature ears to hear, but it should show up on an audio spectrum analyzer. And it is incredibly uncomfortable for ears that can hear it.

Note that this issue was originally reported in 16587378; however, it was incorrectly closed as a duplicate of 16072146. This issue is NOT related to the ongoing noise problem at the Newlyweds factory.
