I've designed a creature for my alien world that is a large apex predator known commonly as a wraith. It lives mostly in dense jungle and forest and uses stealth and ambush to catch its prey (it can take down creatures the size of a horse). Its senses include the contextually unimportant taste and touch, a sense of smell as strong as or slightly stronger than a dog and thermal sensors on its snout. The thermal is important, because it is completely blind (a result of its subterranean ancestry). Its hearing is also extremely sensitive, and can pick up high frequencies. The ears themselves are large and form a fixed tunnel that runs down the sides of the head (which is slightly elongated) from the brow.
I've contemplated adding echolocation to the wraith's arsenal, taking advantage of its sensitive hearing and reinforcing its spacial awareness, as well as giving it a powerful advantage against competition (as a disclaimer, it is part of group of blind predators, a majority of life isn't blind on this planet).
My question is, at which point does strong hearing stop being an advantage and start being a hindrance? (sudden loud noises damaging hearing, especially when human machinery comes close).
