How do you know that it would? The discoverer of the fossil said this about the inner ear: "In the case of pakicetids, the absence of air sinuses insulating the ears, the firm fusion of the periotic to the surrounding bones, and the presence of a flat tympanic membrane suggest that reception of airborne sound is well developed, but are inconsistent with good underwater hearing. It is most likely that the specializations of the pakicetid middle ear are analogous to those of some subterranean mammals and are related to the reception of substrate-borne vibrations or sound when the head is in contact with the ground. Turtles are in close contact with the substrate and gather sensory information using this method"
I am not, but I am not making the claim either way. See the point about the humans and sonar? If you look at our ear you wouldn't think we could use sonar but some people can. Whose to say that hearing developed first in early whales? Whose to say that some wiring in the brain or soft tissues that aren't preserved helped underwater hearing? Maybe it was an ambush predator in water and hearing vibrations on stone helped it? Who knows for certain? This is what Creationists don't understand. Evolution isn't perfect. However, we do know for certain that only modern cetaceans have the bones that we see in Pakicetus. We do know that other proto/primative whales shared that bone and teeth. We know that their skulls have common characteristics, are older than whales, and were found near the seas where some of the earliest whales were found.
Also, I didn't ignore those other fossils. I spent an hour looking through the first 30 google links, reading wikipedia, talk origins and any other website I could find on pakicetus and decided to start with this one.
If someone admits to me "ok, that's a pretty iffy speciman of whale evolution" I'll move on. If they change my mind, and show me why it is a great example of whale evolution (besides just stating "because scientists say it is"), I'll accept it. Thus far, no one has done either, so I'm not going to take the time to go through the other ones.
Here is the problem - what would make it a better specimen? This is what always happens, the moving of the goal posts. It is a good example, it is a logical example, is it 100% certainty - no, of course not. However, that doesn't disprove evolution, it just means there are limits
to what science can do. Initially, a whale ancestor wouldn't look much like a whale, any more than you or I look like a small rodent, or even further back like a microscopic single cell. If you aren't convinced because the differences are too vast then that is fine - but the other fossils are probably much closer to what you are looking for. Dinosaurs and birds are another decent example especially now that we have fossilized skin imprints and other evidence.
