ADVANCEMENTS IN PSYCHOPHYSICS LEAD TO A NEW UNDERSTANDING OF LOUDNESS IN NORMAL HEARING AND HEARING LOSS
AbstractPsychophysics has brought us to a better understanding of loudness growth in subjects withnormal hearing and hearing loss of primarily cochlear origin. Three trends in psychophysicshave led the way: (1) investigations of the relationship between temporal integration ofloudness and the loudness function, (2) investigations of individual differences in loudnessfunctions among normal listeners and listeners with different types of hearing losses, and (3)investigations of how context affects loudness. These trends were aided by technologicaldevelopments that permitted large amounts of data to be modeled. This has importanttheoretical implications for understanding loudness in people with normal hearing andhearing losses, as well as applied applications to improve hearing-aid design.
