“…For instance, amplitude modulations or fluctuations (Gustafsson and Arlinger, 1994); energy allocation in the frequency spectrum of noise (Kaplan and Pickett, 1982;Prosser et al, 1991); and the existence of linguistic information in background noise (Bacon et al, 1998) may have differential effects on speech intelligibility. However, comparison of results is somewhat difficult because these studies differed in the types of background noise, scoring method, and test materials used; syllables, words, and sentences that differ in the amount of contextual cues were used across studies.…”

This study examined (1) the effects of noise on speech understanding and (2) whether performance in real-life noises could be predicted based on performance in steady-state speech-spectrum-shaped noise. The noise conditions included a steady-state speech-spectrum-shaped noise and six types of real-life noise. Thirty normal-hearing adults were tested using sentence materials from the Cantonese Hearing In Noise Test (CHINT). To achieve the first aim, the performance-intensity function slopes in these noise conditions were estimated and compared. Variations in performance-intensity function slopes were attributed to differences in the amount of amplitude fluctuations and the presence of competing background speech. How well the data obtained in real-life noises fit the performance-intensity functions obtained in steady-state speech-spectrum-shaped noises was examined for the second aim of the study. Four out of six types of noise yielded performance-intensity function slopes similar to that in steady-state speech-spectrum-shaped noise. After accounting for individual differences in sentence reception threshold (SRT) and the offset between the signal-to-noise ratio for 50% intelligibility across different types of noise, performance in steady-state speech-spectrum-shaped noise was found to predict well the performance in most of the real-life noise conditions.

“…At moderate suprathreshold levels, binaural loudness summation results in a loudness increase equivalent to about 6 dB greater than the monaural signal (e.g., Epstein & Florentine, 2009; Gigerenzer & Strube, 1983; Irwin, 1965; Moore & Glasberg, 2007; Zwicker & Zwicker, 1991). The increase in the overall loudness of the binaural signals results in approximately a 5% increase in binaural SI; however, this value depends to some degree on the listening conditions and base monaural intelligibility (Davis, Haggard, & Bell, 1990; Harris, 1965; Kaplan & Pickett, 1982).…”

“…Most people notice little decline in hearing ability before 45 or 50; however, with each passing decade, 112 Journal of the International Listening Association a greater loss in hearing sensitivity occurs. When distinguishing the phonemes of the language becomes difficult, spoken words become blurred, especially under listening conditions with reverberation, simultaneous conversation, or environmental noise (Kaplin & Pickett, 1982;Nabelek & Robinson, 1982). Ultimately then, the inability of a presbycusic individual to distinguish phonemes leads to greater difficulty in apprehending the content of spoken communication.…”

Presbycusis, the age associated decline in hearing and listening, has been traditionally conceptualized as the progressive inability to distinguish phonemes and hence to apprehend the content of spoken communication. Based on the distinction between the content and relational dimensions of communication, this study posed the possibility thatpresbycusis also involves a loss of listening ability along the relatwnal dimension of communication. Using five measures of speech discrimination and listening, the study confirmed that aging is significantly associated with losses on the content and relational dimensions of listening. Furthermore, there are different rates of aging for these two dimensions. Whereas the loss on the content dimension is linearly related to age, the loss on the relational dimension is curvilinearly related to age with little decline in ability until a relatively drastic loss occurs in the early to mid-70s. These results indicate that the communicative impact of presbycusis is considerably greater for the old elderly than for the young elderly. Thus, this study constitutes initial evidence for a multidimensional conception ofpresbyCUSis.
