How would a sound be heard if a person is in front of a smooth surface it is reflecting of off?

Technically, the person would hear the sound twice ... once when it passes him on the way toward the smooth surface, and once after it reflects from the surface and passes him again in the opposite direction. In practice, though, you can't detect two seperate sounds if they come too close together in time. So the person standing near the wall could only hear both sounds if he's something like 56 feet or more from it. (0.1 second delay between the incident & reflected sounds)

Smooth surface caries is on a surface that does not have pits, fissures. Usually on the front, back, or side of the tooth as opposed to the top where there are hills and valleys so to say. If the caries is on the crown part of the tooth it started on the enamel, but may have progressed down to the dentin which is the next surface under the enamel.
Rear view mirror anti glare?
rear view mirror ha a wedged shaped glass (unlike rectangular in normal mirrors) and a reflecting surface. in day time the rear surface of the glass is along the reflective surface, hence we see normal reflection. during the night time, in anti glare mode, we tilt only the reflecting surface and not the glass so that the rear surface of the glass leaves the reflecting surface. light rays striking the front surface of the glass gets reflected as well as refracted. the partly reflected rays shows us the rear view which is now of reduced intensity. the refracted ray gets reflected by the reflecting surface but do not meet the eyes. The reflected rays coming from the reflecting surface and meeting the eyes are now from the car's ceiling. the reflection of the ceiling may repress the rear view if the ceiling is lighted. rgds nimish
