Background/Objectives: Hearing loss is frequently misunderstood by communication partners and healthcare providers of patients with hearing loss alike, leading to gaps in counseling, medical adherence, and empathy. Hearing loss simulation is a technique that can clarify patient experience by illustrating how hearing loss affects daily listening and speech discrimination. The current research explores the influences of a web-based hearing loss simulator on how hearing loss is understood by communication partners, audiologists, and medical providers/students. Methods: Using a convergent parallel mixed-methods design, 72 participants (communication partners, audiologists, and medical providers/residents) completed a guided trial with the hearing simulator, either one-on-one or in group settings, and subsequently completed a questionnaire regarding their experiences. The simulation trial included demonstrations of hearing loss and amplification across four listening environments: speech in quiet, in noise, at a distance, as well as listening to instrumental music. Results: Communication partners reported that they gained a better understanding of their partner’s hearing loss, with all expressing increased feelings of empathy towards their partner and individuals with hearing loss. When compared to audiologists, communication partners were significantly more surprised by the impact of hearing loss on speech understanding. Medical providers and students emphasized the value of the simulator as a counseling tool and highly recommended that other providers use the simulator with their patients. Conclusions: Simulating hearing loss can be beneficial for counseling purposes and medical training. These findings suggest that hearing loss simulation can enhance empathy and communication across clinical and educational contexts.

Background/Objectives: Dizziness is a symptom of many disorders across a wide range of etiologies. If dizzy patients are seen for vestibular evaluation with an audiologist and no vestibular reason for the patient’s dizziness is found, the medical referral pathway can become convoluted. This can leave patients feeling discouraged and unable to manage their symptoms. Clinically symptomatic chronic respiratory alkalosis (CSCRA) is an acid–base disorder that typically presents with dizziness but is unfamiliar to practitioners in vestibular and balance care settings. Methods: In a retrospective chart review deemed exempt by the Mayo Clinic Institutional Review Board, 74 patients at Mayo Clinic Arizona were included. All had consultations with both Audiology and Aerospace Medicine to assess their dizzy symptoms. Results: After completing vestibular testing, arterial blood gas (ABG) testing, and a functional test developed at Mayo Clinic Arizona called the Capnic Challenge test, 40% of patients were found to have CSCRA contributing to their dizzy symptoms. Many of these patients also had common comorbidities of CSCRA, like postural orthostatic tachycardia syndrome (POTS), migraines, and sleep apnea. Fewer than one-fourth of these patients had measurable vestibulopathies causing their dizziness. Half of the patients referred by the vestibular audiologist to Aerospace Medicine had a diagnosis of CSCRA. Conclusions: Assessment for CSCRA should be considered as a next step for patients presenting with dizziness without a vestibular component. Being aware of the prevalence of CSCRA and its comorbidities may help balance providers offer quality interprofessional referrals and improve patient quality of life.
