The National Institute for Occupational Safety and Health (NIOSH) evaluated continuous and impact noise exposures and hearing loss among workers at a hammer forge company. Full-shift personal noise exposure measurements were collected on forge workers across 15 different job titles; impact noise characteristics and one-third octave band noise levels were assessed at the forge hammers; and 4,750 historic audiometric test records for 483 workers were evaluated for hearing loss trends. Nearly all workers' noise exposures exceeded regulatory and/or recommended exposure limits. Workers working in jobs at or near the hammers had full-shift time-weighted average noise exposures above 100 decibels, A-weighted. Impact noise at the hammers reached up to 148 decibels. Analysis of audiometric test records showed that 82% of workers had experienced a significant threshold shift, as defined by NIOSH, and 63% had experienced a standard threshold shift, as defined by the Occupational Safety and Health Administration (OSHA). All workers with an OSHA standard threshold shift had a preceding NIOSH significant threshold shift which occurred, on average, about 7 years prior. This evaluation highlights forge workers' exposures to high levels of noise, including impact noise, and how their hearing worsened with age and length of employment.

The past decade has been characterized by significant changes in the distribution and sale of hearing aids. Alternatives to the clinical technology, clinical channel, clinical service (i.e., traditional) hearing healthcare delivery model have been driven by growth in hearing aid dispensaries housed in large retail establishments and direct-to-consumer hearing aid sales by internet-based companies unaffiliated with major hearing aid manufacturers (e.g., Eargo). These developments have been accompanied by acceleration in the growth of teleaudiology services as a direct result of the COVID-19 pandemic. The resulting development of nontraditional hearing aid distribution and sales models can be categorized into distinct archetypes as reviewed earlier in this publication. This article will review the Clinical Technology-Consumer Channel-Clinical Service model as exemplified by Jabra Enhance. We will describe a completely digital model of hearing aid distribution and sales that maintains the professional service component throughout the client journey to include an online tone test, the use of a risk mitigation questionnaire, virtual consultations, remote hearing aid adjustments, and the establishment and monitoring of client-centered treatment goals. Furthermore, this article will review the Jabra Enhance model within the context of consumer healthcare decision-making theory with a focus on the Consumer Decision-Making Model.

Audiology is experiencing exponential growth in technology, service, and provision options. These advancements give hearing care professionals the opportunity to revise, potentially improve, and adapt to the modern hearing care landscape to better serve the modern consumer. Consumer needs guide care planning and delivery, with the goal of achieving outcomes that are important to both the consumer and the clinician. The changes available to the hearing care industry can also enable consumers' needs to be identified and served in a more holistic and personalized manner than has previously been possible. The purpose of this article is to explain and encourage hearing care professionals to adopt a mindset of doing whatever is reasonable and clinically appropriate to meet the need and desires of the consumer by implementing choice in service, technology, and channel across whichever model of care adopted by a provider.

New technologies and developments in hearing healthcare are rapidly transforming service models, delivery channels, and available solutions. These advances are reshaping the ways in which care is provided, leading to greater personalization, service efficiencies, and improved access to care, to name a few benefits. Connected hearing care is one model with the potential to embrace this "customized" hearing experience by forging a hybrid of health-technology connections, as well as traditional face-to-face interactions between clients, providers, and persons integral to the care journey. This article will discuss the many components of connected care, encompassing variations of traditional and teleaudiology-focused services, clinic-based and direct-to-consumer channels, in addition to the varying levels of engagement and readiness defining the touch points for clients to access a continuum of connected hearing care. The emerging hearing healthcare system is one that is dynamic and adaptive, allowing for personalized care, but also shifting the focus to the client's needs and preferences. This shift in the care model, largely driven by innovation and the growing opportunities for clients to engage with hearing technology, brings forth new, exciting, and sometimes uncomfortable discussion points for both the provider and client. The modern hearing care landscape benefits clients to better meet their needs and preferences in a more personalized style, and providers to better support and address those needs and preferences.

Hearing care is expanding accessibility to consumers through new service delivery channels and methods of technology distribution (see Brice et al, this issue). This diversification has the potential to overcome longstanding consumer disparities (e.g., health, socioeconomic, psychological, environmental) in receiving care and provider constraints (e.g., accessibility, geography, direct access) to delivering care that adversely impacts quality of life (e.g., social isolation, depression, anxiety, self-esteem). In this article, the reader is provided with an overview of health outcomes factors (i.e., determinants of health)-in the context of an economic framework (i.e., supply, demand)-and their effect on consumer behavior and provider preferences toward hearing healthcare services. This overview also affords readers with strategic business insights to assess and integrate future hearing care services and technology to consumers in their local markets.

The continuous advancements in technologies supporting digital health and digital therapeutics (DTx) bring new possibilities to the field of audiology. This study considers a new DTx for tinnitus called Tinnibot and the willingness of a group of Australian university audiology students to consider this new DTx in their future careers as practicing audiologists. A single-group case-series design (pretest/posttest) was used to examine the opinions of 10 university audiology students before and after participating in a 2-hour information workshop on the topics of tinnitus, DTx, cognitive behavioral therapy, and a new digital therapy tool for tinnitus called Tinnibot. Student knowledge levels of the main topic areas increased from poor (before the workshop) to moderate to high after the workshop, with 40% of participants reporting they would very likely use digital therapies for future patients. A common barrier to improving this rating was the need for direct hands-on training on the DTx before the students would be confident to recommend the DTx to patients. Incorporating direct training on DTx into university audiology programs would allow greater uptake of DTx by students as they begin their careers as practicing audiologists.

The hearing healthcare industry is evolving rapidly. A framework addressing provision options in contemporary hearing care could assist clinician and client navigate their options to find the most appropriate solution for each individual. A PRISMA approach was used followed by mapping, validation, and thematic analysis to produce a framework to better describe and discuss service and product delivery options in contemporary hearing care. No frameworks were identified to advise matching needs with current provision options in audiological care. Charting, mapping, and thematic analysis of the validation criteria and hearing care literature produced three core domains: Service, Channel, and Technology/Device. The framework developed in this review allows for an understanding of where innovation is occurring in hearing healthcare and differentiates between changes to technology, channel, and service. New questions open up such as whether one model is more effective than another or which model of hearing help is best for which type of person. This framework allows for the disambiguation of hearing health services, hearing loss technology, and the channel in which services and technology are delivered. It has potential to be a versatile and valuable addition to the industry of hearing healthcare.

Healthcare systems are traditionally a clinician-led and reactive structure that does not promote clients managing their health issues or concerns from an early stage. However, when clients are proactive in starting their healthcare earlier than later, they can achieve better outcomes and quality of life. Hearing healthcare and the rehabilitation journey currently fit into this reactive and traditional model of care. With the development of service delivery models evolving to offer services to the consumer online and where they are predominately getting their healthcare information from the internet and the advancement of digital applications and hearing devices beyond traditional hearing aid structures, we are seeing a change in how consumers engage in hearing care. Similarly, as the range of hearing devices evolves with increasingly blended and standard levels of technology across consumer earbuds/headphones and medical grade hearing aids, we are seeing a convergence of consumers engaging earlier and becoming increasingly aware of hearing health needs. This article will discuss how the channels, service, and technology are coming together to reform traditionally clinician-led healthcare models to an earlier consumer-led model and the benefits and limitations associated with it. Additionally, we look to explore advances in hearing technologies and services, and if these will or can contribute to a behavioral change in the hearing healthcare journey of consumers.

The goal of this study was to examine the effect of hearing loss on theta and alpha electroencephalography (EEG) frequency power measures of performance monitoring and cognitive inhibition, respectively, during a speech-in-noise task. It was hypothesized that hearing loss would be associated with an increase in the peak power of theta and alpha frequencies toward easier conditions compared to normal hearing adults. The shift would reflect how hearing loss modulates the recruitment of listening effort to easier listening conditions. Nine older adults with normal hearing (ONH) and 10 older adults with hearing loss (OHL) participated in this study. EEG data were collected from all participants while they completed the words-in-noise task. It hypothesized that hearing loss would also have an effect on theta and alpha power. The ONH group showed an inverted U -shape effect of signal-to-noise ratio (SNR), but there were limited effects of SNR on theta or alpha power in the OHL group. The results of the ONH group support the growing body of literature showing effects of listening conditions on alpha and theta power. The null results of listening condition in the OHL group add to a smaller body of literature, suggesting that listening effort research conditions should have near ceiling performance.
