“…Why this particular question showed significant differences, in the absence of effects of processing condition on the speech perception tasks, is unclear. The lack of an overall effect on the remainder of survey items is consistent with the equivocal sound quality results with nonlinear frequency compression using conservative settings (Bohnert et al, 2010;Parsa et al, 2013;Brennan et al, 2014;Mussoi and Bentler, 2015).…”

“…Others have reported that listeners with hearing loss do not rate the quality of speech differently from conventional processing across a range of frequency compression settings, with the exception of poorer ratings for conditions with a start frequency of compression below 2 kHz (Parsa et al, 2013). Music perception has been reported to be either unaffected (Parsa et al, 2013;Brennan et al, 2014) or negatively affected (Mussoi and Bentler, 2015) by nonlinear frequency compression, with poorer ratings associated with more aggressive frequency compression settings (Mussoi and Bentler, 2015). The overall pattern of results suggests that conservative frequency-lowering settings may not negatively affect perceived sound quality but that lower start frequencies and more aggressive compression ratios do have the potential to negatively impact sound quality.…”

Background Sloping hearing loss imposes limits on audibility for high-frequency sounds in many hearing aid users. Signal processing algorithms that shift high-frequency sounds to lower frequencies have been introduced in hearing aids to address this challenge by improving audibility of high-frequency sounds. Purpose This study examined speech perception performance, listening effort, and subjective sound quality ratings with conventional hearing aid processing and a new frequency-lowering signal processing strategy called frequency composition (FC) in adults and children. Research Design Participants wore the study hearing aids in two signal processing conditions (conventional processing versus FC) at an initial laboratory visit and subsequently at home during two approximately six-week long trials, with the order of conditions counterbalanced across individuals in a double-blind paradigm. Study Sample Children (N = 12, 7 females, mean age in years = 12.0, SD = 3.0) and adults (N = 12, 6 females, mean age in years = 56.2, SD = 17.6) with bilateral sensorineural hearing loss who were full-time hearing aid users. Data Collection and Analyses Individual performance with each type of processing was assessed using speech perception tasks, a measure of listening effort, and subjective sound quality surveys at an initial visit. At the conclusion of each subsequent at-home trial, participants were retested in the laboratory. Linear mixed effects analyses were completed for each outcome measure with signal processing condition, age group, visit (prehome versus posthome trial), and measures of aided audibility as predictors. Results Overall, there were few significant differences in speech perception, listening effort, or subjective sound quality between FC and conventional processing, effects of listener age, or longitudinal changes in performance. Listeners preferred FC to conventional processing on one of six subjective sound quality metrics. Better speech perception performance was consistently related to higher aided audibility. Conclusions These results indicate that when high-frequency speech sounds are made audible with conventional processing, speech recognition ability and listening effort are similar between conventional processing and FC. Despite the lack of benefit to speech perception, some listeners still preferred FC, suggesting that qualitative measures should be considered when evaluating candidacy for this signal processing strategy.

“…However, the cutoff frequency in such hearing aids is usually chosen to be above 2000 Hz, and people are relatively insensitive to mistuning between the lower harmonics and the very high harmonics [85]. Results from a recent study suggest that mild amounts of frequency compression with a high cutoff frequency do not adversely affect music perception, but stronger compression or lower cutoff frequencies have detrimental effects [86].…”

“…16,17 Findings for music perception suggest ratings are unaffected, on average, 14,17 or are negatively affected by stronger settings. 18 This relates to the concept of FL, which is aimed at improving audibility of high-frequency sound, but introduces distortion to the aided signal.

This article provides a review of the current literature on the topic of frequency lowering hearing aid technology specific to the treatment of severe and profound levels of hearing impairment in child and adult listeners. Factors to consider when assessing listener candidacy for frequency lowering technology are discussed. These include factors related to audiometric assessment, the listener, the type of hearing aid technology, and the verification and validation procedures that can assist in determining candidacy for frequency lowering technology. An individualized candidacy assessment including the use of real-ear verification measures and carefully chosen validation tools are recommended for listeners requiring greater audibility of high-frequency sounds, when compared with amplification via conventional hearing aid technology.
