Special Issue Information

Dear Colleagues,

There are several perspectives in the field of audiology with respect to education and research in various countries. Adapting a description from, for example, Germany: “Audiology deals with all aspects of auditory perception—that is, the study of hearing and all related phenomena as well as the prevention, diagnosis, and treatment of hearing disorders”. The Mayo Clinic (in the USA) delineates several specialty areas of audiology, including pediatrics, geriatrics, balance, cochlear implants, hearing aids, tinnitus, and auditory processing. To this list, we can also add issues related to the education and social welfare of individuals with hearing disorders.

According to the World Health Organization (WHO; https://www.who.int/health-topics/hearing-loss#tab=tab_1), about 20% of the world’s population, or 1.5 billion people, have some degree of hearing loss. “By 2050, nearly 2.5 billion people are projected to have some degree of hearing loss, and at least 700 million will require hearing rehabilitation.” There is a wide range of impacts on unaddressed hearing loss, including communication, language, cognition, social isolation, dementia, education, and employment.

For this Special Issue of Audiology, we have selected five critical research strands: ototoxicity, presbycusis, gene therapy, stem cell therapy, and advances in hearing technology. Ototoxicity addresses hearing conditions affected by chemicals or medications. Presbycusis focuses on the progressive and irreversible decline in hearing due to the aging process. Gene therapy addresses faculty DNA, which causes a type of inherited deafness. Stem cell therapy concerns the regeneration of damaged tissues in the inner ear, such as hair cells. Finally, advances in hearing technology provide the current status of hearing devices, such as hearing aids and cochlear implants, and their impact on the language and literacy development of d/Deaf and hard-of-hearing individuals.

These five strands represent some of the cutting-edge research being conducted to improve hearing, affecting a significant percentage of the world’s population. Each article should contextualize the importance of the strand and synthesize the scholar’s work in that area. Each article should also provide recommendations for further research. The information in this Special Issue highlights the necessity of preventing, identifying, and rehabilitating hearing loss on multiple levels as one avenue for improving the quality of life for affected individuals

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Audiology Research is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Purpose: This study examines the potential associations between salivary cortisol concentrations and subjective stress test scores in healthy individuals subjected to sound-related, psychological, and physical stressors. Methods: This study employed a single-center observational cross-sectional design, with a sample size of 36 subjects recruited from a tertiary referral audiology center. Between 2023 and 2024, the study recruited subjects with normal hearing, baseline salivary cortisol levels, and subjective stress levels. The participants were requested to complete an STAI-Y1 questionnaire and provide salivary cortisol samples before and following exposure to sound-related, psychological, and physical stress tests. Results: Exposure to psychological and physical stressors significantly increased STAI-Y1 scores (Friedman’s test, χ2 = 57.118, df = 2, p = 0.377). This increase was greater than that observed in response to loud, favorite music (Friedman’s test, χ2 = 57.118, df = 2, p < 0.0001). The salivary cortisol concentration significantly increased in all three provocation tests (Friedman’s test, χ2 = 95.264, df = 5, p < 0.0001). Furthermore, there is no significant difference in salivary cortisol concentrations between the three pre-test and post-test measurement intervals, indicating a comparable stress-inducing pattern regardless of the nature of the stimulus (Friedman’s test, χ2 = 95.264, df = 5, p > 0.05). Conclusions: Exposure to loud favorite music increases salivary cortisol concentrations, as does acute physical and psychological stress. Interestingly, unlike psychological and physical stress, loud music was not objectively perceived as stress, which may mask the physiological signs of stress, potentially increasing the risk of both acute and chronic stress-related health outcomes.
