Abstract: The use of hearing aids can provide plasticity to the hearing system as well as improve speech recognition as time goes by. Aim:To compare the influence of the length of hearing aid use on the benefit obtained with the hearing aids in adults and the elderly, new hearing aids users. Materials and methods:Prospective study with 40 individuals with mild to moderate-severe sensorineural hearing loss, gathered in 2 groups: Adults Group -13 people aged between 28 and 59 years old; and Elderly Group -27 people aged b… Show more

Purpose The study aimed to investigate the underlying mechanisms of perceived benefit of hearing aid acclimatization. Specifically, measures in the auditory and cognitive domain were tapped to investigate its relationship with the perceived benefit. Method Twenty-six individuals with sensorineural hearing loss served as participants for the study. The perceived benefit of hearing aid use was assessed using the Speech, Spatial and Qualities of Hearing Scale (SSQ; Gatehouse & Noble, 2004 ). Signal-to-noise ratio-50 (SNR-50) and acceptable noise levels were the measures in auditory domain, whereas working memory and listening effort (LE) were the measures in cognitive domain. All the measures were tracked over a span of 2 months of hearing aid use to determine the benefits of hearing aid acclimatization. Results The SSQ showed improvements from baseline to 2nd month of hearing aid use. The mean improvement in the SNR-50 scores was 3.19 dB from the baseline. Acceptable noise levels and working memory did not change with hearing aid use. LE showed improvements in quiet but not in noise. The improvements in the SSQ were found to relate with the improvements in SNR-50. Conclusions The study indicated a significant perceived benefit with hearing aid acclimatization, and the underlying mechanism appears to be the signal-to-noise ratio gain. The findings of LE indicated reduced LE, thereby suggesting lesser cognitive load with hearing aid acclimatization. In addition, the individuals who performed poorer in the baseline measurement showed greater perceived benefit with hearing aid acclimatization.

Objectives: Audiologists and hearing aid users (HAUs) generally agree that an adaptation period is needed following the first hearing aid (HA) experience. The main purpose of this study is to investigate the acclimatization of older adult listeners with hearing loss to HAs using listening effort and behavioral measures. Design: Participants (N=47) were older adults with mild to moderately severe sensorineural hearing loss. Thirty-two participants were new HAUs and 15 participants were experienced HAUs. New HAUs were randomly assigned to one of two groups: noise reduction algorithms and directional microphones activated or noise reduction algorithms and directional microphones deactivated. Speech recognition in noise and listening effort were assessed on 8 different occasions during a 10-month period. A dual-task paradigm was used to measure the listening effort deployed to recognize speech in noise. The primary task consisted of the Hearing in Noise Test which also served as the behavioral speech in noise measure. The secondary task was a tactile pattern-recognition task in which participants had to identify a sequence of three tactile stimuli that varied in duration. The two listening effort outcomes were the proportional dual-task cost and the response time on the secondary task. Cognitive abilities, including working memory and speed of processing, were evaluated using the Reading Span Test and the Digit Symbol Substitution Test, respectively. Results: Results show a significant time*group interaction. Both groups of new HAUs showed improvement over time in speech in noise performances (change of ~2 dB signal to noise ratio) and the experienced HAUs did not improve over time. The acclimatization effect was observed over a period of 4 weeks. There was no significant change over time on both measures of listening effort. There was no association between amplitude of acclimatization and the cognitive abilities measured. Conclusion: An acclimatization effect following HA experience was observed. Specifically, the new HAUs displayed a clinically significant change of 2 dB in signal to noise ratio on the Hearing in Noise Test 4 weeks following their initial fitting. The acclimatization effect is not correlated to cognitive abilities.
