“…When we compared the results between the HINT and WHOQOL-BREF in situation A, there was no significant relationship. This can be justified by the fact that the individuals selected for this study showed a slope hearing loss with hearing preserved to 1 kHz, and in most cases, individuals with this audiometric configuration demonstrate good speech recognition performance in quiet situations 9 . In addition, the individuals evaluated had moderate losses at high frequencies, with an average threshold at 8 kHz of around 60 dBNA, which contributes to better speech recognition.…”

“…The speech intelligibility depends on the consonant sounds that present sound spectrum with frequencies above 2 kHz. The fact that the consonants are low intensity sounds in relation to vowels makes them more difficult to detect, especially for individuals with slope hearing loss 9 . The purpose of amplification in individuals with this audiological profile is to provide an emphasis on high frequencies sounds, providing audibility of speech signal without generating acoustic feedback or distortion, and avoiding autophonia from the occlusion of the external auditory canal (EAC) by the earmold.…”

Objective To relate the performance of individuals with hearing loss at high frequencies in speech perception with the quality of life before and after the fitting of an open-fit hearing aid (HA).Methods The WHOQOL-BREF had been used before the fitting and 90 days after the use of HA. The Hearing in Noise Test (HINT) had been conducted in two phases: (1) at the time of fitting without an HA (situation A) and with an HA (situation B); (2) with an HA 90 days after fitting (situation C).Study Sample Thirty subjects with sensorineural hearing loss at high frequencies.Results By using an analysis of variance and the Tukey’s test comparing the three HINT situations in quiet and noisy environments, an improvement has been observed after the HA fitting. The results of the WHOQOL-BREF have showed an improvement in the quality of life after the HA fitting (paired t-test). The relationship between speech perception and quality of life before the HA fitting indicated a significant relationship between speech recognition in noisy environments and in the domain of social relations after the HA fitting (Pearson’s correlation coefficient).Conclusions The auditory stimulation has improved speech perception and the quality of life of individuals.

“…Correlation analyses have been used in several studies either to quantify the amount of E recovered from the TFS speech signal as compared to the original speech signals (e.g., Zeng et al, 2004;Gilbert and Lorenzi, 2006;Li et al, 2015) or to depict the similarities of the E or TFS between two types of signals Xu, 2016). In the present study, we adopted the latter approach.…”

“…In previous work, correlation analyses were performed to evaluate the amount of E recovery from TFS speech at the output of cochlear filtering (Zeng et al, 2004;Gilbert and Lorenzi, 2006;Li et al, 2015) or to compare the similarities of the acoustic E or TFS of two type of speech materials Xu, 2016). The latter approach was adopted in the present study to allow us to examine the similarities of the acoustic E or TFS between the original tone tokens and the masker-corrupted tone tokens.…”

Previous studies have shown that lexical tone perception in quiet relies on the acoustic temporal fine structure (TFS) but not on the envelope (E) cues. The contributions of TFS to speech recognition in noise are under debate. In the present study, Mandarin tone tokens were mixed with speech-shaped noise (SSN) or two-talker babble (TTB) at five signal-to-noise ratios (SNRs; -18 to +6 dB). The TFS and E were then extracted from each of the 30 bands using Hilbert transform. Twenty-five combinations of TFS and E from the sound mixtures of the same tone tokens at various SNRs were created. Twenty normal-hearing, native-Mandarin-speaking listeners participated in the tone-recognition test. Results showed that tone-recognition performance improved as the SNRs in either TFS or E increased. The masking effects on tone perception for the TTB were weaker than those for the SSN. For both types of masker, the perceptual weights of TFS and E in tone perception in noise was nearly equivalent, with E playing a slightly greater role than TFS. Thus, the relative contributions of TFS and E cues to lexical tone perception in noise or in competing-talker maskers differ from those in quiet and those to speech perception of non-tonal languages.

“…Of all those with SNHL, even individuals with only HF SNHL usually complain about the intelligibility of fast speech, especially in noise. Accumulated evidence shows that the speech recognition scores of HF SNHL patients with normal low-frequency hearing are poorer than those of NH individuals, even when speech stimuli are limited to low frequencies [ 6 – 10 ]. Age also played an important role in speech perception [ 11 ].…”

This study explored whether the time-compressed speech perception varied with the degree of hearing loss in high-frequency sensorineural hearing loss (HF SNHL) individuals. 65 HF SNHL individuals with different cutoff frequencies were recruited and further divided into mildly, moderately, and/or severely affected subgroups in terms of the averaged thresholds of all frequencies exhibiting hearing loss. Time-compressed speech recognition scores under both quiet and noisy conditions and gap detection thresholds within low frequencies that had normal thresholds were obtained from all patients and compared with data from 11 age-matched individuals with normal hearing threshold at all frequencies. Correlations of the time-compressed speech recognition scores with the extents of HF SNHL and with the 1 kHz gap detection thresholds were studied across all participants. We found that the time-compressed speech recognition scores were significantly affected by and correlated with the extents of HF SNHL. The time-compressed speech recognition scores also correlated with the 1 kHz gap detection thresholds except when the compression ratio of speech was 0.8 under quiet condition. Above all, the extents of HF SNHL were significantly correlated with the 1 kHz gap thresholds.
