Factors influencing hearing distance You have questions, we have answers. Dogs ears are also built in a formation that helps them receive sound waves more clearly than humans. Its thanks to their predatory heritage that dogs can hear high-pitched sounds so well. This is why they are also more likely to respond to commands given in a higher-pitched tone of voice. The problem is that vehicles offer very little protection from radiation and fallout. On the other hand, we can locate sounds better than dogs. We know that when a loud sound is played, our auditory neurons will respond, but they respond in a pretty haphazard fashion.
