As people move through the activities of daily living at home, at work, and in social or business situations, basic auditory abilities take on functional significance. Audition makes it possible to detect and recognize meaningful environmental sounds, to identify the source and location of a sound, and, most importantly, to perceive and understand spoken language. The ability of an individual to carry out auditory tasks in the real world is influenced not only by his or her hearing abilities, but also by a multitude of situational factors, such as background noise, competing signals, room acoustics, and familiarity with the situation. Such factors are important regardless of whether one has a hearing loss, but the effects are magnified when hearing is impaired.
