“…In humans, these ages equate approximately with adolescence and early adulthood respectively, thus it may be that humans who sustain noise exposure while teenagers might be expected to have poorer HF and EHF thresholds than those first exposed at a later age. Taken together, these findings suggest that elevated EHF thresholds are an early indicator that subclinical damage has occurred and it may be prudent to test thresholds at some or all of these frequencies for patients who present with speech-in-noise difficulties or suspected noise damage (Rodríguez Valiente et al, 2016). 4.5.…”

The effects of noise exposure and musical training on suprathreshold auditory processing and speech perception in noise

et al. 2017

Recent animal research has shown that exposure to single episodes of intense noise causes cochlear synaptopathy without affecting hearing thresholds. It has been suggested that the same may occur in humans. If so, it is hypothesized that this would result in impaired encoding of sound and lead to difficulties hearing at suprathreshold levels, particularly in challenging listening environments. The primary aim of this study was to investigate the effect of noise exposure on auditory processing, including the perception of speech in noise, in adult humans. A secondary aim was to explore whether musical training might improve some aspects of auditory processing and thus counteract or ameliorate any negative impacts of noise exposure. In a sample of 122 participants (63 female) aged 30-57 years with normal or near-normal hearing thresholds, we conducted audiometric tests, including tympanometry, audiometry, acoustic reflexes, otoacoustic emissions and medial olivocochlear responses. We also assessed temporal and spectral processing, by determining thresholds for detection of amplitude modulation and temporal fine structure. We assessed speech-in-noise perception, and conducted tests of attention, memory and sentence closure. We also calculated participants' accumulated lifetime noise exposure and administered questionnaires to assess self-reported listening difficulty and musical training. The results showed no clear link between participants' lifetime noise exposure and performance on any of the auditory processing or speech-in-noise tasks. Musical training was associated with better performance on the auditory processing tasks, but not the on the speech-in-noise perception tasks. The results indicate that sentence closure skills, working memory, attention, extended high frequency hearing thresholds and medial olivocochlear suppression strength are important factors that are related to the ability to process speech in noise.

“…However, studies using extended high‐frequency audiometry (8 kHz–16 kHz) reported downward threshold shifts in patients who had a history of recurrent acute otitis media. The extended high‐frequency audiometry, although not validated for clinical use, is used to monitor patients under a high risk of hearing loss (who work in noisy environments, who will be subjected to chemotherapy or radiation therapy, or who have tinnitus with normal thresholds in the standard audiometry) . Although mainly used in research, extended high‐frequency audiometry is also used in some clinical protocols to detect early changes to the auditory thresholds and to plan early intervention when possible …”

“…Hence, the TEOAEs assayed in this study may not be sensitive enough to reveal changes in sensitivity, especially in revealing changes to high frequency hearing at the base of the cochlea. Once enrolled in the study, participants underwent detailed evaluation that included EHF audiometry (8–16 kHz) as a secondary indicator of early hearing damage 36 and a three week dosimetry protocol to objectively measure daily average noise exposure levels and evaluate risk of noise-induced hearing loss. To capture sound levels representative of daily routines, participants wore a noise dosimeter clipped to their clothing for a total of ~ 21 days, spread across an academic year.…”

Serological biomarkers of inner ear proteins are a promising new approach for studying human hearing. Here, we focus on the serological measurement of prestin, a protein integral to a human’s highly sensitive hearing, expressed in cochlear outer hair cells (OHCs). Building from recent nonhuman studies that associated noise-induced OHC trauma with reduced serum prestin levels, and studies suggesting subclinical hearing damage in humans regularly engaging in noisy activities, we investigated the relation between serum prestin levels and environmental noise levels in young adults with normal clinical audiograms. We measured prestin protein levels from circulating blood and collected noise level data multiple times over the course of the experiment using body-worn sound recorders. Results indicate that serum prestin levels have a negative relation with noise exposure: individuals with higher routine noise exposure levels tended to have lower prestin levels. Moreover, when grouping participants based on their risk for a clinically-significant noise-induced hearing loss, we found that prestin levels differed significantly between groups, even though behavioral hearing thresholds were similar. We discuss possible interpretations for our findings including whether lower serum levels may reflect subclinical levels of OHC damage, or possibly an adaptive, protective mechanism in which prestin expression is downregulated in response to loud environments.
