1. The sensation of sound persisting in our brain for about 0.1 seconds, known as auditory persistence, allows us to hear distinct echoes by distinguishing between the original sound and subsequent reflections, despite their close temporal proximity.

  2. The minimum distance for hearing distinct echoes changes with air temperature because sound speed varies with temperature. Warmer air increases sound speed, resulting in shorter minimum distances for distinct echoes, and vice versa.
