In the short term, audio enhancement technologies in inexpensive mobile forms, devices that are quickly becoming necessary to navigate all aspects of our lives, can bring better audio signals to many people. Alternatively, current speech recognition technology may obviate the need for audio amplification or enhancement at all and could be useful for listeners with normal hearing or with hearing loss. With new and dramatically better technology based on deep neural networks, speech enhancement improves the signal to noise ratio, and audio classifiers can recognize sounds in the user's environment. Both use deep neural networks to improve a user's experiences. Longer term, auditory attention decoding is expected to allow our devices to understand where a user is directing their attention and thus allow our devices to respond better to their needs. In all these cases, the technologies turn the hearing assistance problem on its head, and thus require new ways to measure their performance.With an ongoing shift from managing disease toward the inclusion of maintaining health and preventing disease, the world has seen the rise of increasingly sophisticated physiological monitoring and analytics. Innovations range from wearables, smartphone-based spot monitoring to highly complex noncontact, remote monitoring, utilizing different mechanisms. These tools empower the individual to better navigate their own health. They also generate powerful insights towards the detection of subclinical symptoms or processes via existing and novel digital biomarkers. In that context, a topic that is receiving increasing interest is the modulation of human physiology around an individual "baseline" in everyday life and the impact thereof on other sensorineural body functions such as hearing. More and more fully contextualized and truly long-term physiological data are becoming available that allows deeper insights into the response of the human body to our behavior, immediate environment and the understanding of how chronic conditions are evolving. Hearing loss often goes hand in hand with chronic conditions, such as diabetes, cognitive impairment, increased risk of fall, mental health, or cardiovascular risk factors. This inspires an interest to not only look at hearing impairment itself but to take a broader view, for example, to include contextualized vital signs. Interestingly, stress and its physiological implications have also been shown to be a relevant precursor to hearing loss and other chronic conditions. This article deduces the requirements for wearables and their ecosystems to detect relevant dynamics and connects that to the need for more ecologically valid data towards an integrated and more holistic mapping of hearing characteristics.Recent epidemiological findings of associations between hearing loss (HL) and poorer mobility and higher falls risk have increased the demand for ecologically valid experimental research to determine the potential mechanisms underlying human hearing-balance relationships. This review provides an overview of the laboratory-based approaches to studying human balance, identifies crucial factors that should be considered to improve the ecological validity of hearing-balance research, and provides a critical review of the scientific literature to date on the effects of HL on balance. Most present studies can be subdivided into those that examine balance changes due to the effects of (1) auditory suppression in individuals with normal hearing, (2) HL with and without hearing aids, and (3) cochlear implants in children and adults. To allow for meaningful comparisons, we based our in-depth critical review on studies that met minimum criteria of having at least one objective kinetic or kinematic measure of standing baships between HL, balance, and falls.The negative consequences of hearing loss go beyond difficulties with communication, having been identified as a major risk factor for injury and illness, social isolation, depression, overall quality of life, and mortality. Hearing loss affects the individual, their families and social network, the broader healthcare system, and the economy. Recognizing that there are multifactorial considerations associated with understanding and mitigating the consequences of hearing loss, great benefit is gained by taking an interdisciplinary, interprofessional, holistic approach to studying hearing loss in research and in developing holistic clinical strategies targeted at prevention, diagnosis, treatment, and social policy. Within the framework of this supplement focused on the role of ecological validity in hearing-related research and application, this article provides a general commentary on how ecological validity can be considered with a holistic perspective in mind. First, we consider how a holistic approach can be applied within clinical practice, how it can be applied to laboratory-based research to increase ecological validity, and how it can be applied to professional training and education within both research and clinical domains. Second, we discuss the associations between hearing loss and dementia as an example of how these holistic principles can be applied. The main goal of highlighting these approaches and principles is to motivate a change in the narrative about hearing loss from a focus in research and application on promoting healthy hearing, to a focus on living well.In this article, we examine ecological validity in hearing science from a qualitative methodological perspective. We present an overview of qualitative methods, presenting their key characteristics and contrasting these techniques with quantitative approaches to enquiry. We argue that ecological validity sits at the heart of the qualitative paradigm and seek to clearly emphasize the methodological gap that could be effectively filled by qualitative or mixed methods. In doing so, we discuss qualitative methods that may work particularly well in enhancing ecological validity in hearing science and explore their range of applications in this field. These approaches can be applied to a wide range of hearing health research questions to present a unique understanding of people's experiences of disease and disability, indicating gradations of personal health and illness in nuanced ways. We acknowledge and commend the current expansion of qualitative methods within hearing science and present recommendations for increasing ecological validity, both in the design of future studies and in the context of the wider research cycle. We call on qualitative researchers to strive for transparency, rigor, and trustworthiness and highlight challenges to be overcome if qualitative methods are to contribute to effective, efficient research strategies. Oxaliplatin To facilitate the transference of high-quality research findings into practice, we stress the need for joined-up working to create a research culture that promotes coproduction of ecologically valid research designs, involving not only hearing researchers but also implementation scientists, hearing healthcare professionals and, most importantly, people with hearing loss for whom these efforts could make a difference.Common methods to assess hearing deficits and the benefit of hearing devices include retrospective questionnaires and speech tests under controlled conditions. As typically applied, both approaches suffer from serious limitations regarding their ecological validity. An alternative approach rapidly gaining widespread use is ecological momentary assessment (EMA), which employs repeated assessments of individual everyday situations. Smartphones facilitate the implementation of questionnaires and rating schemes to be administered in the real life of study participants or customers, during or shortly after an experience. In addition, objective acoustical parameters extracted from head- or body-worn microphones and/or settings from the hearing aid's signal processing unit can be stored alongside the questionnaire data. The advantages of using EMA include participant-specific, context-sensitive information on activities, experienced challenges, and preferences. However, to preserve the privacy of all communication partners and bystanders, the law in many countries does not allow audio recordings, limiting the information about environmental acoustics to statistical data such as, for example, levels and averaged spectra. Other challenges for EMA are, for example, the unsupervised handling of the equipment, the trade-off between the accuracy of description and the number of similar listening situations when performing comparisons (e.g., with and without hearing aids), the trade-off between the duration of recording intervals and the amount of data collected and analyzed, the random or target-oriented reminder for subjective responses, as well as the willingness and ability of the participants to respond while doing specific tasks. This contribution reviews EMA in hearing research, its purpose, current applications, and possible future directions.The objective of this study was to obtain a normative database of speech intelligibility data for young normal-hearing listeners communicating in public spaces. A total of 174 listeners participated in an interactive speech intelligibility task that required four-person groups to conduct a live version of the Modified Rhyme Test in noisy public spaces. The public spaces tested included a college library, a college cafeteria, a casual dining restaurant during lunch hour, and a crowded bar during happy hour. At the start of each trial, one of the participants was randomly selected as the talker, and a tablet computer was used to prompt them to say a word aloud from the Modified Rhyme Test. Then, the other three participants were required to select this word from one of six rhyming alternatives displayed on three other tablet computers. The tablet computers were also used to record the SPL at each listener location during and after the interval where the target talker was speaking. These SPL measurements were used to estimate the signal-to-noise ratio (SNR) in each trial of the experiment. As expected, the results show that speech intelligibility decreases, response time increases, and perceived difficulty increases as the background noise level increases. There was also a systematic decrease in SNR with increasing background noise, with SNR decreasing 0.44 dB for every 1 dB increase in ambient noise level above 60 dB. Overall, the results of this study have demonstrated how low-cost tablet computer-based data collection systems can be used to collect live-talker speech intelligibility data in real-world environments. We believe these techniques could be adapted for use in future studies focused on obtaining ecologically valid assessments of the effects of age, hearing impairment, amplification, and other factors on speech intelligibility performance in real-world environments.Humans have evolved the unique capacity to efficiently communicate using the spoken word. Hearing plays a key role as a receiver in this process and dysfunction leads to difficulties in listening and communication. It is widely accepted that effective communication is not adequately captured with current behavioral speech tests that principally focus on passive sound detection and speech recognition with idealized stimuli. To address the question of what it will take to obtain more ecologically valid outcomes from behavioral speech tests, recent approaches, and test paradigms devised to address some of the acknowledged shortcomings of current speech tests were reviewed. Additionally, some recent work which has focused on understanding brain function in social and dynamic interaction scenarios, so-called second person neuroscience, was reviewed. These reviews revealed that, while recent efforts in bridging the gap between behavioral speech tests and everyday communication situations represent important steps in the right direction, they are unlikely to provide a complete account of everyday communication situations.
