Audiology is a noun that refers to the medicine concerned with the sense of hearing. 

Our word of the day combines the Latin word ‘audire,’ (OW dee ray) which means ‘hear’ with the Greek suffix O-L-O-G-Y, meaning ‘study of.’ A fairly recent addition to the language, audiology is a study that can assist someone hoping to learn more about the science of hearing. 

Even after all those classes in audiology, I never could understand what makes some songs sound better than others. But maybe my preference for late nineties hip-hop polka is destined to remain a mystery.
