Background: People with hearing loss (HL) report several challenging situations in working life (WL). HL can negatively affect, e.g., the ability to communicate, creating barriers and difficulties in WL. However, there is a lack of studies that investigates salutary aspects in relation to working conditions for the target group. Sense of Coherence (SOC) is a salutary concept widely used when investigating aspects in WL but is less explored in relation to HL. Objective: To explore the concept of Sense of Coherence (SOC) in relation to working conditions for employees with HL. Methods: An observational study with a cross-sectional design including people with HL in working age using hearing aids (HAs) or cochlear implants (CIs). Comparisons were made between participants “in work” and participants on “HL-related sick leave”. Results: The “in work” group reported a higher SOC compared to the “HL-related sick leave” group. The analysis showed significant differences between the two groups in all three dimensions of SOC with the “in work” group being better off in almost all investigated variables. Conclusion: SOC is a valuable concept for investigating working conditions for employees with HL. The results indicate that to increase the possibility of salutary working conditions, it is necessary to focus on consequences of HL, such as the need for recovery, autonomy and support. Addressing these aspects increases employees’ comprehension of and ability to manage the work situation and their sense of meaningfulness, which may act as a buffer against work-related stress and reduce the risk of sick leave.

Objective: Investigate hearing function and headphone listening habits in nine-year-old Swedish children. Design: A cross-sectional study was conducted and included otoscopy, tympanometry, pure-tone audiometry, and spontaneous otoacoustic emissions (SOAE). A questionnaire was used to evaluate headphone listening habits, tinnitus, and hyperacusis. Study sample: A total of 415 children aged nine years. Results: The prevalence of a hearing threshold ≥20 dB HL at one or several frequencies was 53%, and the hearing thresholds at 6 and 8 kHz were higher than those at the low and mid frequencies. SOAEs were observed in 35% of the children, and the prevalence of tinnitus was 5.3%. No significant relationship between SOAE and tinnitus was found. Pure-tone audiometry showed poorer hearing thresholds in children with tinnitus and in children who regularly listened with headphones. Conclusion: The present study of hearing, listening habits, and tinnitus in nine-year old children is, to our knowledge, the largest study so far. The main findings were that hearing thresholds in the right ear were poorer in children who used headphones than in children not using them, which could be interpreted as headphone listening may have negative consequences to children’s hearing. Children with tinnitus showed poorer hearing thresholds compared to children without tinnitus.
