“…A regression analysis for weeks 1 to 8 showed a nonsignificant (NS) negative performance slope during this time, indicating that virtually all the improvement occurred during the first week. These small improvements are similar to those of a recent acclimatization study where linear HAs produced an average improvement of 2.2 percent in NST scores in the first 8 weeks of use, a result attributed to procedural learning of the task rather than acclimatization [26].…”

“…Figure 8 (solid gray line) plots the mean change in phoneme-recognition performance over the training period for the experienced HA users in Experiment 2. Measures of the amplification benefit had been made previously with the same stimuli from the NST presented at 5 dB SNR through ear inserts incorporating signal amplification [26]. Performance averaged 36.0 and 45.8 percent correct for these subjects' initial unaided and aided conditions, respectively, indicating a robust HA amplification effect of 9.8 percent (F 1, 7 = 10.6, p = 0.01).…”

“…One would think that restoring speech cues with an HA would be sufficient to reestablish normal connections during acclimatization. However, acclimatization effects for most types of HAs are small in magnitude and difficult to distinguish from improvement due to increased familiarity with test materials [26]. Acclimatization is unsuccessful for several possible reasons.…”

“…Eight experienced HA users (mean HA experience = 16 months, range 10-21 months) were recruited from a group of subjects who had participated in a previous study that evaluated acclimatization with 9-and 16-channel HAs with wide dynamic range compression [26]. As part of that study, these subjects had participated in more than 60 hours of in-laboratory NSTs with two of the four voices used in the present study.…”

Abstract-We assessed the effects of perceptual training of syllable identification in noise on nonsense syllable test (NST) performance of new (Experiment 1) and experienced (Experiment 2) hearing aid (HA) users with sensorineural hearing loss. In Experiment 1, new HA users were randomly assigned to either immediate training (IT) or delayed training (DT) groups. IT subjects underwent 8 weeks of at-home syllable identification training and in-laboratory testing, whereas DT subjects underwent identical in-laboratory testing without training. Training produced large improvements in syllable identification in IT subjects, whereas spontaneous improvement was minimal in DT subjects. DT subjects then underwent training and showed performance improvements comparable with those of the IT group. Training-related improvement in NST scores significantly exceeded improvements due to amplification. In Experiment 2, experienced HA users received identical training and testing procedures as users in Experiment 1. The experienced users also showed significant training benefit. Trainingrelated improvements generalized to untrained voices and were maintained on retention tests. Perceptual training appears to be a promising tool for improving speech perception in new and experienced HA users.

“…15 Furthermore, the benefits of hearing aids are hugely affected by individual characteristics such as personality, motivation and expectations; they also depend on the acoustic ambience within which each subject is present. 16 A study of the perceptual acclimatization phenomenon in adult new hearing aid users 2 found that the mean speech recognition percentage rate improved after four and 16/18 weeks of amplification use, although this difference was not statistically significant.…”

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 between 61 and 78 years old. These people were assessed 14 and 90 days after hearing aid fitting. Sentence recognition threshold in silence and under noise as well as the percentage indexes of sentences recognition in silence and under noise were obtained. Results:The comparison between values obtained after 14 and 90 days of hearing aid use did not show statistically significant differences. When comparing values between the groups, no statistically significant difference was observed either. Conclusion:We did not find influences of the length of hearing aid use and the benefit obtained from using them; the results achieved by adults and the elderly were similar.

Hearing Aid Use in Children With Unilateral Hearing Loss: A Randomized Crossover Clinical Trial

Objectives/Hypothesis: In children with mild to moderately severe unilateral hearing loss (UHL), assess whether subject-reported quality of life (QOL) and teacher-and parent-reported perception of listening difficulty are affected by use of a hearing aid (HA) with baseline accommodations, compared to children receiving only baseline accommodations.Study Design: Randomized crossover clinical trial. Methods: Thirty-seven children 6-12 years of age with mild to moderately severe UHL and ≥80% word recognition scores in the poorer hearing ear were randomized into arm 1, using baseline accommodations (frequency-modulated system and strategic seating) for 12 weeks, followed by addition of a HA for 12 weeks. The other participants were randomized into the reverse methodology: arm 2, using a HA in addition to baseline accommodations for 12 weeks, followed by baseline accommodations alone. Surveys of QOL (Hearing Environments and Reflection on Quality of Life) and listening difficulties or challenges with hearing amplification (CHILD and LIFE-R questionnaires) were administered at 6-week intervals. Differences in mean survey scores, percent change, and improvement over time were computed between the two arms and inter-arm intervals. Per-protocol analysis was used.Results: Of the 37 children enrolled, 34 children underwent the study interventions and were included in the analysis, (arm 1 = 20, arm 2 = 14) (mean [standard deviation] age = 8 [1.5] years; 21 boys [61.8%]). Survey scores averaged across both arms during the HA interval (77.79 [15.13]) were significantly higher than during the baseline-only interval (69.67 [14.69], P = .036). There was no significant difference between trial arms in mean scores between the two HA intervals (P = .450) and two baseline-only intervals (P = .539).Conclusions: Hearing-related QOL and listening ability improved in children who met eligibility criteria with mild to moderately severe UHL with HA use compared with baseline accommodations alone. Trial Registration: ClinicalTrials.gov identifier: NCT02269124.
