“…BS8300 regulation in the UK or EN 60118-4 standard) in order to ensure high quality sound for users of hearing aids. The users of assistive listening devices reported that speech intelligibility and general satisfaction with sound perception is efficiently improved in rooms equipped with an induction loop (Kociński, Ozimek 2015). Participants of the line-up sessions who use hearing aids might then simply be asked to switch the hearing aid to T-mode for the induction loop signal receiver.…”

The main goal of this research was to discover the influence of high frequency sensorineural hearing loss on familiar speaker recognition during earwitnessing line-ups. The secondary objectives were to estimate the influence of familiarity with voices of the suspects on performance in the auditory speaker recognition test, and to correlate the results with forensically important factors such as a confidence scale from the line-up markings. The recordings from the line-up sessions were low-pass filtered to ensure an equal degree of signal distortion for all subjects and imitate the moderate, severe and profound hearing loss conditions. The results show that the correlation between mimicked hearing impairment and ability to identify a familiar speaker is statistically significant. It was observed that higher degree of signal distortion caused lower accuracy of recognition. Interestingly, it was reported that higher levels of familiarity and exposure to speakers’ voices had a negative effect on speaker identification.

“…Therefore, for listeners who are predominantly concerned with communication in these environments, listener age and degree of hearing loss (to a lesser extent) may be the best factors with which to infer a listener’s susceptibility to the reverberation. On the other hand, a large church may have a reverberation time as high as 5 seconds (Kociński and Ozimek, 2015). For listeners most concerned with communication in an environment with such severe reverberation, it would be better to consider the listener’s working memory capacity (measured using the RST) and age as clinical predictors.…”

“…Sentences were processed and presented at three possible reverberation times: no reverberation (0.0 seconds), moderate reverberation (1.0 seconds), or severe reverberation (4.0 seconds). These three reverberation conditions were selected because they represent the range of reverberant degradation found in the real world (Hodgson et al, 2007; Kociński and Ozimek, 2015). See Figure 2 for an example of the same sentence waveform in each of the three reverberation conditions.…”

The results suggest that suprathreshold listener factors can be used to best predict speech intelligibility across a range of reverberant conditions. However, which listener factor(s) to consider when predicting a listener's susceptibility to reverberation depends on the amount of reverberation in an environment. Clinicians may be able to use different listener factors to identify individuals who are more susceptible to reverberation and would be more likely to have difficulty communicating in reverberant environments.

The Chinese word identification and sentence intelligibility are evaluated by grades 3 and 5 students in the classrooms with different reverberation times (RTs) from three primary school under different signal-to-noise ratios (SNRs). The relationships between subjective word identification and sentence intelligibility scores and speech transmission index (STI) are analyzed. The results show that both Chinese word identification and sentence intelligibility scores for grades 3 and 5 students in the classroom increased with the increase of SNR (and STI), increased with the increase of the age of students, and decreased with the increase of RT. To achieve a 99% sentence intelligibility score, the STIs required for grades 3, grade 5 students, and adults are 0.71, 0.61, and 0.51, respectively. The required objective acoustical index determined by a certain threshold of the word identification test might be underestimated for younger children (grade 3 students) in classroom but overestimated for adults. A method based on the sentence test is more useful for speech intelligibility evaluation in classrooms than that based on the word test for different age groups. Younger children need more favorable classroom acoustical environment with a higher STI than older children and adults to achieve the optimum speech communication in the classroom.
