- Bakgrund och syfte Personer med hörselnedsättning behöver ofta anstränga sig för att höra och att lyssna uppmärksamt under en längre tid kan bli kognitivt krävande. Forskning visar att det kan resultera i lyssningströtthet. Andra studier visar att personer som arbetar i stökiga ljudmiljöer beskriver snarlika upplevelser även om hörseln inte är nedsatt. Detta har benämnts ljudtrötthet. Lyssningströtthet kan ha en negativ påverkan på livskvalitet och arbetsprestation och kan innebära svårigheter att delta i sociala aktiviteter eller andra viktiga lyssningskrävande aktiviteter. Det finns även samband med stress. På liknande vis har ljudtrötthet beskrivits av förskollärare ge effekter både emotionellt, kognitivt inklusive mental trötthet, fysiskt och socialt. Även förskollärarna beskriver att de drar sig undan sociala sammanhang och att de är i behov av återhämtning efter en arbetsdag i intensiv ljudmiljö. Vanderbuilt Fatigue Scale for Adults (VFS-A-40) är ett validerat självskattningsinstrument utvecklat i USA för att kvantifiera lyssningströtthet hos vuxna. Det finns idag inget instrument på svenska som specifikt mäter lyssningströtthet. Det saknas också jämförelse mellan lyssningströtthet och symptomet ljudtrötthet bland personer som arbetar i intensiva ljudmiljöer. Syftet med studien är dels att översätta och utvärdera VFS-A-40 på svenska bland personer som har hörselbesvär, dels att undersöka förekomsten av lyssningströtthet bland kvinnor i Sverige generellt och specifikt bland de som arbetar i intensiva ljudmiljöer, samt jämföra med förekomst av ljudtrötthet. Metod och förväntat resultat I detta projekt har vi översatt instrumentet till svenska och vi genomför nu en kvalitativ utvärdering (inklusive face validity) av den svenska versionen av VFS-A-40 genom kognitiva intervjuer bland patienter inom hörselvården (datainsamling pågår, antalet intervjuer beräknas totalt till minst 10). Vi kommer även genomföra kvantitativa statistiska analyser (inklusive analys av construct validity och internal consistency) av kortversionen av det översatta mätinstrumentet (VFS-A-10) samt två ytterligare enskilda items från VFS-A-40, i jämförelse med enkätfrågor om ljudtrötthet och hyperacusis (HQ, Hyperacusis Questionnaire Khalfa et al 2002, och HIQ, Hyperacusis Impact Questionnaire Aazh et al 2022). De statistiska analyserna genomförs på och prevalens beräknas utifrån ett stort epidemiologiskt datamaterial omfattande drygt 10 000 kvinnor i åldrarna 34 – 80 år, varav hälften är slumpmässigt utvalda från befolkningen och resterande är förskollärare (datainsamling pågår, beräknad svarsfrekvens ca 60%). Preliminära resultat från tre kognitiva intervjuer indikerar inga behov av justeringar för att behålla betydelsen från originalinstrumentet VFS-A-40. Chronbach’s alpha för VFS-A-10, samband mellan lyssningströtthet, ljudtrötthet och hyperacusis, samt prevalens av respektive symptom kommer att presenteras. I presentationen diskuteras även planerade studier för klinisk validering och implementering.

Tidskriftsartikel (refereegranskat)abstract
- A participatory-based intervention was performed in Sweden, aimed at improving the sound environment in one preschool (n=20) and one obstetric ward (n=50), with two controls each (n=28, n=66). Measured sound levels, and surveys of noise annoyance, hearing-related symptoms and emotional exhaustion were collected before, and three and nine months after the interventions, comparing intervention and control groups over time. The results of this first implementation in a limited number of workplaces showed significantly worsening of hyperacusis, sound-induced auditory fatigue, emotional exhaustion and increased sound levels in the preschool, and worsening of noise annoyance in both intervention groups. Increased risk awareness, limited implementation support and lack of psychosocial interventions may explain the worsening in outcomes, as might the worse baseline in the intervention groups. The complexity of the demands in human-service workplaces calls for further intervention studies.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The aim was to study preschool teachers experience of sound-induced auditory fatigue. Previous studies have shown increased risk of sound-induced auditory fatigue, as well as other hearing-related symptoms, among female preschool teachers compared to women in general. Based on a sample of female preschool teachers who responded to a follow-up survey 2017 (n3277), we analysed open-ended free-text responses from n852 teachers who worked in preschool part- or fulltime, and experienced sound-induced auditory fatigue at least once a month or more often. We used qualitative content analysis to code and categorised the responses based on an interpretation of latent underlying meaning. The categories were then conceptualized into a model. We identified that the context relating to the sound-environment at the preschool was a contributing factor to the symptom sound-induced auditory fatigue, and many of the preschool teachers expressed a need for silence as a result of the noise exposure at work. The teachers expressed several negative health effects, which were interpreted as resulting from an unfulfilled need for auditory recovery. These effects were sub-categorised into 1) emotional effects (including annoyance), 2) cognitive effects (including mental fatigue), 3) physical effects (including hearing-related symptoms e.g., hyperacusis, and stress-reactions), and 4) social effects (including withdrawal). The teachers also described coping strategies adopted to meet the need for recovery or to handle the effects of the auditory fatigue. We conclude that the sound environment in preschool and the subsequent auditory fatigue and related negative health effects experienced by many preschool teachers require attention and prevention.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Personnel in communication-intense workplaces are exposed to noise, occasionally so high they risk hearing-related disorders. Still, intervention studies are few, with ambiguous results. To increase the impact and sustainability of the interventions, we used a participatory method in which personnel and managers at one preschool and one obstetrics ward were actively involved in the intervention process. To identify work environment problems to target in the intervention, we performed qualitative focus group interviews prior to the intervention among 16 personnel and managers. Four main themes emerged from the inductive thematic analysis: a challenging and harmful sound environment, the sound environment causing hearing-related symptoms and health effects, a good sound environment not being prioritised, and resourceful and motivated personnel. As the participatory intervention entailed implementation of several changes, we also performed interviews post-intervention among nine personnel and managers from the preschool and the obstetrics ward where interventions had been implemented. Five main themes emerged from the inductive thematic analysis: increased awareness of the sound environment and risks to hearing and health, increased control over the sound environment, influence of the building and interior design, other factors influencing the intervention process (concurrent work environment issues such as stress, and limited resources), and motivation to maintain the positive changes. We conclude that the personnel perceive a risk to their hearing and health and that sound environment improvements should be prioritised in communication-intense workplaces. A participatory approach may facilitate motivation and empowerment to change, but resources and support are needed for comprehensive and effective implementation.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of the study was to explore and describe how workers in communication-intenseworkplaces in health care and preschools experience the sound environment. The depen-dence on vocal communication and social interaction poses a challenge using hearing pro-tection in these working environments.Method: A qualitative method was used, more specifically inductive thematic analysis was used, asthis approach was deemed suitable to explore the staff’s experiences of the sound environ-ment. Data were collected by interviews and to increase trustworthiness, several researcherswere involved in the data collection and analysis.Study sample: Workers from two preschools, one obstetrics ward and one intensive care unit took part inthe study.Results: Four main themes emerged from the thematic analysis: A challenging and harmful soundenvironment; Health-related effects of a challenging and harmful sound environment; Agood sound environment is not prioritised; and Resourceful and motivated staff.Conclusions: Workers in communication-intense workplaces in preschools, obstetrics care and intensivecare reported that there was a relationship between the sound environment and negativehealth effects. In addition, the results suggests that the high motivation for change amongstaff should be utilised together with an increased prioritization from the management toreach innovative context specific improvements to the sound environment in communicationintense working environments.
