Ear drums with holes in them have trouble staying tight like a drum and reduce hearing ability. So everyone who hears well probably has whole ear drums. Even if you develop a hole, it usually heals over within a month or two.

It is actually thought that hearing is one of the very first senses a fetus develops - before it's large enough to brush up against the amnion walls regularly, it can hear sounds... and better than after birth (water transmits sound much better than air).

Many newborn babies, for example, can actually recognize the sound of their parents' voices. One of the brightest memories of my own life was from the birth of my son: he knew me right off and calmed down for the first time in my arms when I sang to him (poor mom had a c-section and wasn't in much shape to do a lot of holding right then).

Not usually. In some cases the eardrum is incomplete due to trauma, infection, or faulty development. The extent of hearing impairment varies; a small hole in an otherwise intact and normal eardrum may have little practical effect, although it will keep you out of the Army.

In ancient times it was not unusual for people to have perforated ear drums due to childhood infections; thus the technique of pouring poison in the ear (mentioned by Shakespeare) which would pass through the incomplete eardrum, down th Eustachian tube and straight into the throat. (Why this never seemed to wake up the victim is not clear.)
