Purpose The purpose of this article is to assess speech processing for listeners with simulated age-related hearing loss (ARHL) and to investigate whether the observed performance can be replicated using an automatic speech recognition (ASR) system. The long-term goal of this research is to develop a system that will assist audiologists/hearing-aid dispensers in the fine-tuning of hearing aids. Method Sixty young participants with normal hearing listened to speech materials mimicking the perceptual consequences of ARHL at different levels of severity. Two intelligibility tests (repetition of words and sentences) and 1 comprehension test (responding to oral commands by moving virtual objects) were administered. Several language models were developed and used by the ASR system in order to fit human performances. Results Strong significant positive correlations were observed between human and ASR scores, with coefficients up to .99. However, the spectral smearing used to simulate losses in frequency selectivity caused larger declines in ASR performance than in human performance. Conclusion Both intelligibility and comprehension scores for listeners with simulated ARHL are highly correlated with the performances of an ASR-based system. In the future, it needs to be determined if the ASR system is similarly successful in predicting speech processing in noise and by older people with ARHL.

Age Related Hearing Loss

Age-related hearing loss (ARHL), a sensorineural hearing loss of multifactorial origin, increases its prevalence in aging societies. Besides hearing aids and cochlear implants, there is no FDA approved efficient pharmacotherapy to either cure or prevent ARHL. We hypothesized that selegiline, an antiparkinsonian drug, could be a promising candidate for the treatment due to its complex neuroprotective, antioxidant, antiapoptotic, and dopaminergic neurotransmission enhancing effects. We monitored by repeated Auditory Brainstem Response (ABR) measurements the effect of chronic per os selegiline administration on the hearing function in BALB/c and DBA/2J mice, which strains exhibit moderate and rapid progressive high frequency hearing loss, respectively. The treatments were started at 1 month of age and lasted until almost a year and 5 months of age, respectively. In BALB/c mice, 4 mg/kg selegiline significantly mitigated the progression of ARHL at higher frequencies. Used in a wide dose range (0.15–45 mg/kg), selegiline had no effect in DBA/2J mice. Our results suggest that selegiline can partially preserve the hearing in certain forms of ARHL by alleviating its development. It might also be otoprotective in other mammals or humans.

Age Related Hearing Loss

Aging is considered a contributing factor to many diseases such as cardiovascular disease, Alzheimer’s disease, and hearing loss. Age-related hearing loss, also termed presbycusis, is one of the most common sensory impairments worldwide, affecting one in five people over 50 years of age, and this prevalence is growing annually. Associations have emerged between presbycusis and detrimental health outcomes, including social isolation and mental health. It remains largely untreatable apart from hearing aids, and with no globally established prevention strategies in the clinical setting. Hence, this review aims to explore the pathophysiology of presbycusis and potential therapies, based on a recent advancement in bile acid-based bio-nanotechnologies. A comprehensive online search was carried out using the following keywords: presbycusis, drugs, hearing loss, bile acids, nanotechnology, and more than 150 publications were considered directly relevant. Evidence of the multifaceted oxidative stress and chronic inflammation involvement in cellular damage and apoptosis that is associated with a loss of hair cells, damaged and inflamed stria vascularis, and neuronal signalling loss and apoptosis continues to emerge. New robust and effective therapies require drug delivery deeper into the various layers of the cochlea. Bile acid-based nanotechnology has gained wide interest in its permeation-enhancing ability and potential for numerous applications in treating presbycusis.

Age Related Hearing Loss

A number of studies have demonstrated a significant association between age-related hearing loss (ARHL) and cognitive decline. However their relationship is not clear. In this review, we focused on the etiological mechanisms between ARHL and cognitive decline to explain the nature of this relationship: 1) causal mechanisms (e.g., cognitive load hypothesis, cascade hypothesis); 2) common cause mechanisms (e.g., microvascular disease); 3) overdiagnosis or harbinger hypothesis. We conclude that no single mechanism is sufficient and hearing and cognition related to each other in several different ways. In addition, we reviewed the effectiveness of hearing intervention (e.g., hearing aids and cochlear implants) on cognition function, and the role of hearing aid use and cochlear implant depends on the relevant mechanism.

Age Related Hearing Loss

Abstract As the proportion of older adults in the world’s total population continues to grow, the deleterious downstream health economic outcomes of age-related hearing loss are steadily becoming more prevalent. While recent research has shown that age-related hearing loss is the single greatest modifiable risk factor for dementia, the rate of hearing aid use remains low in many countries across the globe. Reasons for poor uptake are multifactorial and likely involve a combination of factors, ranging from increasing costs of hearing aid technology to lack of widespread insurance coverage. This paper aims to first identify the current state of hearing aid access across the world using eight representative countries as examples. We then provide recommendations on how to facilitate greater access to hearing aids for consumers by addressing areas in regulation, technology, reimbursement, and workforce.

Age Related Hearing Loss

AbstractHearing aids are a demonstrated efficacious intervention for age-related hearing loss, and research suggests that good hearing loss self-management skills improve amplification satisfaction and outcomes. One way to foster self-management skills is through the provision of patient education materials. However, many of the available resources related to the management of hearing loss do not account for health literacy and are not suitable for use with adults from varying health literacy backgrounds. To address this issue, we developed the Hearing Loss Toolkit for Self-Management as part of a manualized, best practices hearing intervention used in large clinical trial. We incorporated health literacy recommendations from the U.S. Department of Health and Human Services, the Centers for Disease Control and Prevention, and the Agency for Healthcare Research and Quality in a series of modules that address a variety of common problem areas reported by adults with hearing loss. A formative assessment consisting of feedback questionnaires, semistructured interviews, and a focus group session with representatives from the target audience was conducted. Findings from the development assessment process demonstrate that the Hearing Loss Toolkit for Self-Management is suitable for use with adults with age-related hearing loss who have varying health literacy backgrounds and abilities.
