“…Correlations for aided scores in this group were lower again (standard: r=-0.49, p=0.01; complex: r=-0.39, p<0.05). These correlations are comparable to those reported by Mendel et al (2007), who compared scores on various clinical speech in noise tests to ratings on the Hearing Aid Performance Inventory (their correlations ranged from 0.45 – 0.80).…”

Objective There is increasing demand in the hearing research community for the creation of laboratory environments that better simulate challenging real-world listening environments. The hope is that the use of such environments for testing will lead to more meaningful assessments of listening ability, and better predictions about the performance of hearing devices. Here we present one approach for simulating a complex acoustic environment in the laboratory, and investigate the effect of transplanting a speech test into such an environment. Design Speech reception thresholds were measured in a simulated reverberant cafeteria, and in a more typical anechoic laboratory environment containing background speech babble. Study Sample The participants were 46 listeners varying in age and hearing levels, including 25 hearing-aid wearers who were tested with and without their hearing aids. Results Reliable SRTs were obtained in the complex environment, but led to different estimates of performance and hearing aid benefit from those measured in the standard environment. Conclusions The findings provide a starting point for future efforts to increase the real-world relevance of laboratory-based speech tests.

“…Here, the significant positive correlations found between aided spatial benefit and a subscale of the SSQ supported an association between objective and subjective binaural performance. This is consistent with positive correlations observed by Mendel (2007) between aided HINT thresholds in spatially separated conditions and several categories of the Hearing Aid Performance Inventory (Walden et al 1984). …”

Spatial Benefit of Bilateral Hearing Aids

Objectives To assess the extent to which hearing aids improve spatial benefit by restoring the availability of interaural difference cues, the benefit attributable to spatial separation of speech and babble with and without bilateral hearing aids was measured as a function of low-pass cutoff frequency. Design Twenty-one older adults with sloping high-frequency hearing loss were provided commercially available bilateral hearing aids. After a 3 to 6 month acclimatization period, speech levels corresponding to 50% correct recognition of sentences from the Hearing in Noise Test (HINT) were measured in a 65-dB SPL babble, with speech and babble low-pass filtered at 1.8, 3.6, and 5.6 kHz. Sentences were always at 0° azimuth, and babble was at either 0° or 90°. Speech and babble spectra for all conditions were digitally recorded using a probe microphone placed in each ear canal of each subject. Spectra and levels of speech and babble and unaided thresholds for narrowband noises were used to calculate the aided audibility index and provide predictions of unaided and aided thresholds for HINT sentences, hearing aid benefit, and spatial benefit for each cutoff frequency. In addition, subjects’ willingness to tolerate background noise with and without amplification was measured in the spatially coincident and spatially separated conditions using the Acceptable Noise Level (ANL) procedure. Results Thresholds for HINT sentences in babble and ANL improved significantly when aided and when speech and babble were spatially separated. Specifically, hearing aid benefit improved significantly as cutoff frequency increased from 1.8 to 3.6 kHz but only when speech and babble were spatially separated; likewise, spatial benefit improved significantly from 1.8 to 3.6 kHz but only in the aided condition. No further improvement in hearing aid or spatial benefit was observed when cutoff frequency was increased from 3.6 to 5.6 kHz, although improvement in hearing aid benefit was predicted. Conclusions Hearing aid benefit, although significant, was poorer than predicted, suggesting that these older adults with high-frequency hearing loss did not take full advantage of the increase in audible speech information provided by amplification. Hearing aid benefit was also limited because hearing aids for some subjects did not restore speech audibility across the full bandwidth of speech. Unaided and aided spatial benefit was significantly greater than predicted, and aided spatial benefit was greater than unaided. This suggests that these older adults were able to take advantage of interaural level and time difference cues to improve speech recognition in babble and that they benefited from these cues to a greater extent with than without bilateral hearing aids. Finally, in contrast to results of previous studies, ANL may vary for an individual depending on the listening condition.

RESUMOObjetivo: avaliar o desempenho e a satisfação com o uso das próteses auditivas nos pacientes atendidos no convênio APAC-UFSM, após um ano de adaptação. Método: analisou-se 49 sujeitos, com perda auditiva do tipo neurossensorial ou mista, de grau leve a severo na melhor orelha, divididos em adultos e idosos. Realizou-se a pesquisa dos Limiares e Índices Percentuais de Reconhecimento de Sentenças no Silêncio e no Ruído, em campo livre, por meio do teste Listas de Sentenças em Português; e aplicou-se o questionário de satisfação, International Outcome Inventory for Hearing Aids. Realizaram-se os testes na mesma sessão, em dois momentos distintos, sendo o primeiro, sem o uso das próteses auditivas e o segundo, usando as mesmas.Resultados: houve diferença significante no desempenho dos indivíduos em ambos os grupos, no procedimento realizado no silêncio. Apesar de o desempenho com próteses auditivas não ter apresentado melhora significante no ruído, os pacientes apresentaram respostas satisfatórias no questionário. Na comparação entre os grupos, não se observou diferença significante quanto ao desempenho e satisfação. Conclusão: a melhora significante do desempenho no silêncio vai ao encontro do relato dos pacientes. O questionário evidenciou que a maioria referiu fazer uso efetivo das próteses auditivas e considerou ter um benefício muito satisfatório. Apesar de uma parcela significativa referir moderada ou bastante dificuldade residual, a maioria considerou que o uso das próteses auditivas vale muito ou bastante a pena.
