“…This is because the triplet material itself is actually composed of 10 words, which markedly improves speech intelligibility (Miller et al, 1951;Smits et al, 2004). The difference between SRTs obtained for digit triplets and sentence material is in agreement with the results of measurements for the Dutch language for which SRTs obtained for digit triplet test (Smits et al, 2004) and sentence test (Plomp and Mimpen, 1979) are -11.2 dB and -5.5 dB, respectively. The difference is also noticeable if the SRT obtained for the German digit triplet test (Wagener et al, 2005a) and the German Göttingen sentence test (Kollmeier and Wesselkamp, 1997) are compared.…”

“…characterized by similar and steep intelligibility functions for each list regardless of its index (Plomp and Mimpen, 1979;Nilsson et al, 1994;Kollmeier and Wesselkamp, 1997;Versfeld et al, 2000;Wagener, 2003;Smits et al, 2004;Wagener et al, 2005a;Ozimek et al, 2006). The similarity of SRT values and large S 50 implies low intra-and inter-variability of the lists, i.e.…”

“…The higher the SRT, the poorer is performance. For many of the common speech materials used, and especially for sentence lists (Bench and Bamford, 1979;Plomp and Mimpen, 1979;Nilsson et al, 1994), the percent correct varies quite rapidly with changes in speechto-noise ratio. For example, if the speech-to-noise ratio is set to a value giving about 50% correct, increasing the ratio by 1 dB typically gives an increase in percent correct of 7-19%.…”

People with sensorineural hearing impairment typically have more difficulty than normally hearing people in understanding speech in the presence of background sounds. This paper starts by quantifying the magnitude of the problem in various listening situations and with various types of background sound. It then considers some of the factors that contribute to this difficulty, including: reduced audibility; reduced frequency selectivity; loudness recruitment; and regions in the cochlea which have no surviving inner hair cells and/or neurones (dead regions). Methods of compensating for the effects of some of these factors are described and evaluated. Signal-processing methods to compensate for the effects of reduced frequency selectivity using the output of a single microphone have had only limited success, although methods using multiple microphones have worked well. Amplitude compression can compensate for some of the effects of loudness recruitment, allowing speech to be understood over a wide range of sound levels. The exact form of the compression (fast-acting versus slow-acting, single-channel versus multiple channel) does not seem to be critical, suggesting that the relative loudness of different components of speech, and dynamic aspects of loudness perception do not need to be restored to ''normal''.

“…Based on the data in Figure 10 of Smoorenburg (1992), a 10-dB increase in PTA 2,4 is associated, on average, with a 1.2-dB increase in the SNR required to identify 50% of sentences completely correctly. Such a 1.2-dB change corresponds to a 17% decrease in the number of sentences that can be correctly understood under difficult listening conditions (Plomp & Mimpen, 1979). Thus, if the noise-induced component of the hearing loss leads to an increase in PTA 2,4 of X dB, this would be expected, on average, to decrease the number of correctly identified sentences in noise by X times 1.7%.…”

A review of the perceptual effects of hearing loss for frequencies above 3 kHz

Background: Hearing loss caused by exposure to intense sounds usually has its greatest effects on audiometric thresholds at 4 and 6 kHz. However, in several countries compensation for occupational noise-induced hearing loss is calculated using the average of audiometric thresholds for selected frequencies up to 3 kHz, based on the implicit assumption that hearing loss for frequencies above 3 kHz has no material adverse consequences. This paper assesses whether this assumption is correct. Design: Studies are reviewed that evaluate the role of hearing for frequencies above 3 kHz. Results: Several studies show that frequencies above 3 kHz are important for the perception of speech, especially when background sounds are present. Hearing at high frequencies is also important for sound localization, especially for resolving front-back confusions. Conclusions: Hearing for frequencies above 3 kHz is important for the ability to understand speech in background sounds and for the ability to localize sounds. The audiometric threshold at 4 kHz and perhaps 6 kHz should be taken into account when assessing hearing in a medico-legal context.
