TL;DR: It is suggested that long-term musical practice strengthens cognitive functions and that these functions benefit auditory skills, and musical training may serve to lessen the impact of these deficits by strengthening the corticofugal system for hearing.

TL;DR: Each expert has given their own personal view on the topic and at the end of their commentary they have suggested several experiments that would be required for the decisive mechanism underlying the cochlear amplifier.

TL;DR: Markers of socioeconomic status were associated with hearing impairment, suggesting that hearing impairment in older adults may be associated with modifiable lifestyle and environmental factors, and therefore, at least partially preventable.

TL;DR: Pitch discrimination, as measured by FDLs, and neural representation of frequency, as reflected by FFR, declined as age increased, and one was not predictive of the other.

TL;DR: In most cases, the inner ear's responses to infrasound can be considered normal, but they could be associated with unfamiliar sensations or subtle changes in physiology, which raises the possibility that exposure to the infrasounds of wind turbine noise could influence the physiology of the ear.

TL;DR: Evidence from numerous investigations indicates an age-related decline in encoding of temporal sound features which may be a contributing factor to the deficits observed in speech recognition in many elderly listeners.

TL;DR: The differences the authors observed between the low- and the high-pitch group show that tinnitus pitch might influence the outcome of acoustic stimulation treatments when devices with a limited frequency range are used.

TL;DR: The high frequency displacement amplitude and phase maps discovered in this study can not be explained by any single wave motion, but are consistent with a combination of low and higher order modal motions plus some small traveling-wave-like components.

TL;DR: Both psychophysical and neurophysiological findings are reviewed, which provide some insight into how, and how well, the auditory system accomplishes this task of separating harmonics when two or more harmonic sounds occur concurrently.

TL;DR: N-Acetyl-cysteine protected men against noise-induced temporary threshold shift (TTS), and whether subgroups with genetic polymorphisms of glutathione S-transferase (GST) T1 and M1 responded to NAC differently.

TL;DR: It is suggested that the robustness of subcortical neural encoding of pitch features in time-varying signals is a key factor in determining success with perceiving speech in noise.

TL;DR: Functional differences across layers were consistent with studies showing greatest losses of gamma-aminobutyric acid (GABA) markers in superficial layers of A1 and with anatomic studies showing highest levels of inhibitory neurons located in superficial cortical layers.

TL;DR: Lateral line hair cells of both canal and superficial neuromast types are vulnerable to gentamicin ototoxicity, arguing for a re-evaluation of the results of studies that have used Gentamicin to differentiate the roles of the two classes of neuromasts in fish behavior.

TL;DR: The model shows that higher partial tripolar fractions activate more spatially restricted populations of neurons at all current levels and require higher current levels to excite a given number of neurons.

TL;DR: Age-related differences in complex measures of auditory temporal processing may be explained, in part, by age-related deficits in processing speed and attention.

TL;DR: Cognition and age were found to be significant predictors, although only 10-27% of the variance could be accounted for by these predictors.

TL;DR: The current review discusses ARHL patterns in humans and animal models, followed by discussions of the different prevention techniques.

TL;DR: This work argues that the upper-frequency hearing limit of a given mammalian species can in part be understood in terms of morphological co-adaptations of the eardrum and ossicular chain.

TL;DR: The present work demonstrates the application of a miniaturized pulsed IR stimulator for chronic implantation in cats, quantifies its efficacy, and short-term safety, and validate the stimulation parameters that can be used in future chronic implants based on pulsedIR.

TL;DR: NIRS can measure cortical responses in pediatric CI users, and has the potential to be a powerful adjunct to current CI assessment tools.

TL;DR: A clear relationship was found between the values of f(e) and the mean pitch matches following training; the correlation was 0.94.

TL;DR: This work has shown that the Notch signaling pathway, the Atoh1/Hes signaling cascade, the stem cell marker Sox2, and some of the unconventional myosin motor proteins are utilized to regulate distinct steps in inner ear development.

TL;DR: With the advancement of recent genetic and pharmacologic tools, the authors should not only understand how SGNs die during aging, but also find ways to delay this loss.

TL;DR: An historical perspective on middle ears with a tympanum connected by one or more ossicles to the cochlea is presented, showing how the brain increased in size and a secondary palate developed, resulting in the ancestral pressure-gradient middle ear being replaced by a purely pressure system.

TL;DR: Unexpectedly, permanent reductions in the amplitude of the cochlear compound action potential (CAP) and the auditory brainstem response (ABR) were often observed after the chronic salicylate treatment.

TL;DR: The benefits to speech intelligibility of F0 for both listeners with hearing impairment and users of CIs are reviewed, as well as various methods of delivering F0 to these listeners.

TL;DR: Data indicate that cochlear filters are widened 5% by the MOC activity from moderate-level CBBN, which would have a profound effect on binaural localization if they were not balanced in the central nervous system.

TL;DR: The described characteristics of the aging F344 rat auditory system supports the idea that this strain may serve as a suitable model for studying the mechanisms of presbycusis, its prevention and treatment.

TL;DR: The level of hearing protection in the second turn exceeded that expected from models of steroid diffusion through the cochlea, suggesting that inner ear surgery alters the distribution of dexamethasone within the co chlea.

TL;DR: The results extend those of a previous study, showing that the auditory nerve in humans is preferentially activated by anodic stimulation, to different sites along the cochlea.
