Even fewer continue using them. This talk will address several questions relating to the potential of hearing aids to help people with mild hearing loss. The characteristics of mild loss include reduced frequency selec- tivity, reduced temporal resolution, reduced spatial hearing ability, and increased speech reception threshold in noise. The latter can be used to assess hearing loss over the tele- phone. Although mild loss decreases the audibility and intelligibility of soft speech, diffi- culty listening in noise is the problem most commonly troubling people with mild loss. Hearing aids, by contrast, provide the greatest benefit for soft speech in very low noise levels. Hearing aids with directional microphones do provide benefit in noisy places, but the benefit is typically only a few decibels improvement in speech reception threshold, and room acoustics and open fittings often cause the benefit to be less that that, or even zero. The potential wearer is therefore offered devices that

  • 156 a Half-Century's Perspective on Békésy
    A HALF-CENTURY’S PERSPECTIVE ON BÉKÉSY TRACKING AND LOUDNESS GROWTH AT THRESHOLD 1 1,2 Elizabeth Rooney and Mary Florentine Department of Speech-Language Pathology and Audiology 1 Department of Electrical and Computer Engineering 2 Northeastern University (106-A FR), 360 Huntington Avenue, Boston, MA 02115 USA [email protected] and [email protected] Abstract In the more than half a century since Georg von Békésy was awarded the Nobel Prize, many of his findings have stood the test of time. Implications of the width of the excursions in the Békésy tracking procedure, however, are not as simple as described in his classic book, Experiments in Hearing (von Békésy, 1960). The interpretations of his findings have created some misunderstandings in hearing science and audiology. This article reviews a large body of data on Békésy tracking and more recent threshold, discrimination, and loudness data in order to answer the following question: Is the width of the excursions a reliable indicator of cochlear pathology? In 1947, von Békésy described a new audiometer and claimed that this new audiometer permitted the testing of recruitment. Recruitment has been defined as a rapid growth in loudness above the threshold of hearing (Fowler,1936; Steinberg and Gardner, 1937; Brunt, 1994) and was believed to be associated with all cochlear hearing losses (Dix, Hallpike, and Hood, 1948). The audiometer was automated. As the frequency of the signal increased slowly, the subject pressed a button when the signal was audible and released it when inaudible. This pressing and releasing of the button caused the level of the signal to decrease or increase, respectively, and a visible tracing of the excursions (or trackings) between the just-audible and just-inaudible pulsed tones could be observed on recording paper that was attached to a rotating drum.

  • Loudness Functions for Long and Short Tones
    LOUDNESS FUNCTIONS FOR LONG AND SHORT TONES Mary Florentine,1,2 Michael Epstein,1,3 and Søren Buus1,3 1Institute for Hearing, Speech, and Language 2Dept. of Speech-Language Pathology and Audiology (133 FR) 3Communications and Digital Signal Processing Center, ECE Dept. (440 DA) Northeastern University, 360 Huntington Avenue, Boston, MA 02115 U.S.A. E-mail: [email protected], [email protected], [email protected] Abstract This study tests the Equal-Loudness-Ratio hypothesis [Florentine et al., J. Acoust. Soc. Am. 99, 1633-1644 (1996)], which states that the loudness ratio between equal-SPL long and short tones is independent of SPL. The amount of temporal integration (i.e., the level difference between equally loud short and long sounds) is maximal at moderate levels. Therefore, the Equal-Loudness-Ratio hypothesis predicts that the loudness function is shallower at moderate levels than at low and high levels. Equal-loudness matches and cross- modality string-length matches were used to assess the form of the loudness function for 5- and 200-ms tones at 1 kHz and the loudness ratio between them. Results from nine normal listeners show that (1) the amount of temporal integration is largest at moderate levels, in agreement with previous studies, and (2) the loudness functions are shallowest at moderate levels. For eight of the nine listeners, the loudness ratio between the 200- and 5-ms tones is approximately constant, except at low levels where it tends to increase. The average data show good agreement between the two methods, but discrepancies are apparent for some individuals.

  • Advancements in Psychophysics Lead to a New Understanding of Loudness in Normal Hearing and Hearing Loss
    ADVANCEMENTS IN PSYCHOPHYSICS LEAD TO A NEW UNDERSTANDING OF LOUDNESS IN NORMAL HEARING AND HEARING LOSS Mary Florentine Institute for Hearing, Speech, and Language and Dept. Speech-Language Pathology and Audiology (133 FR) Northeastern University, Boston, MA 02115 USA [email protected] Abstract P sychophysics has brought us to a better understanding of loudness growth in subjects with normal hearing and hearing loss of primarily cochlear origin. Three trends in psychophysics have led the way: (1) investigations of the relationship between temporal integration of loudness and the loudness function, (2) investigations of individual differences in loudness functions among normal listeners and listeners with different types of hearing losses, and (3) investigations of how context affects loudness. These trends were aided by technological developments that permitted large amounts of data to be modeled. T his has important theoretical implications for understanding loudness in people with normal hearing and hearing losses, as well as applied applications to impr ove hear ing-aid design. The purpose of this invited paper is to review some psychophysical developments that have led to a better understanding of loudness in subjects with normal hearing and hearing losses over the past twenty-five years at Northeastern University. As is the case in most of science, knowledge has progressed in incremental steps. Three major areas of investigation are noteworthy and are reviewed in the following sections. 1. Investigations of temporal integration of loudness and the loudness function The puzzling question of how to reconcile two sets of loudness data from normal-hearing listeners has been solved. One set of data clearly indicates that the amount of temporal integration for loudness varies nonmonotonically with level and is greatest at moderate levels (Florentine et al., 1996; Buus et al., 1997).

(Received 6 September 1990) Emotional expression of four levels of six kinds of sound (aircraft noise, train noise, road traffic noise, speech, music and construction noise) was examined using the method of selected description in five countries-Japan, Sweden, West Germany, China and the U.S. Subject were asked to select the adjectives which they thought appropriate for expressing the impression of each sound. Using the method of selected description, the differences and similarities between sound sources and use of adjectives were expressed more clearly than when conventional semantic differential was used. On the basis of the adjectives selected and cluster analysis, it was found for sounds used in this experi mentthat "loud" in Japan, Sweden and China has neutral connotations while "loud" in Germany and the U.S. has negative connotations. It was also suggested that "noisy" and "annoying" are not differentiated in Japan, while in the other four countries these two adjectives are differentially used.
