Abstract
OBJECTIVE To observe total leisure noise (TLN) exposure and to investigate determinants of risky TLN exposure among adolescents and young adults over a ten-year observation period. DESIGN OHRKAN is a longitudinal study with five equidistantly distributed questionnaires (waves) over ten years. Risky TLN exposure was defined as exceeding ≥85dB(A) averaged over 40h per week. To identify determinants of risky TLN exposure longitudinally, generalised estimating equations were applied. STUDY SAMPLE A subgroup (n = 661; mean age 25.6 years in the fifth wave; 58.4% female) of the closed cohort study OHRKAN was analysed. Included participants took part in the fifth wave prior to the study break due to COVID-19. RESULTS Analysis of participants' data from all five waves showed that risky TLN exposure was highest during the second wave (72.0%), when participants were aged 17-19 years, and thereafter steadily declined. Among young adults, attendance at discotheques and private parties, especially, caused very high exposure. Determinants of risky TLN exposure were wave time point, male gender, a higher level of education, and smoking. CONCLUSIONS As TLN exposure is highest among older adolescents, prevention programs should target younger teenagers and be tailored to the identified risk groups. The risk from private parties should be addressed.

Abstract
OBJECTIVE The overall objective in the study was to compare self-reported hearing based on a single question ("how good would you currently rate your hearing?") to measure hearing loss determined by audiometry in a cohort of adolescents. Prevalence of audiometrically measured hearing loss and frequencies of self-reported poor hearing as well as factors that have an impact on self-reported hearing were examined. DESIGN Baseline and 5-year follow-up data of the Ohrkan study were used. Participants filled in a questionnaire and underwent audiometric measurements. STUDY SAMPLE Data from 979 adolescents were analysed. Participants were 54.7% female and aged between 13 and 18 years at baseline and 17-21 years at 5-yr follow-up. RESULTS The single question on self-reported hearing ability achieved a sensitivity of 41.9% and a positive predictive value of 7.1% at baseline. For the 5-yr follow-up, sensitivity was 40.0%, positive predictive value was 13.9%. Factors influencing self-reported poor hearing were gender, tinnitus, "muffled" ears after exposure to loud noise (e.g. after a concert) and low-frequency hearing loss. CONCLUSIONS The single question about hearing ability used in the Ohrkan study is not sufficient to replace audiometry to detect hearing loss as defined in the study in adolescents.

Abstract
OBJECTIVE To examine risky leisure noise exposure from listening to music via headphones and to identify potential determinants with special focus on portable listening devices (PLDs) among adolescents over a period of 7.5-years. DESIGN Data were collected by questionnaires at four equidistant time points (O1-O4). Music exposure via headphones was calculated based on self-reported volume setting and listening duration. Exceeding 85 dB(A) equivalent for a 40-hour working week was defined as risky noise exposure. Determinants of risky headphone and PLD exposure were investigated using generalised estimating equations and accounting for missing data by multiple imputation. STUDY SAMPLE Closed cohort of 2148 students attending 9th grade of any secondary school type in Regensburg (Germany), during 2009 to 2011. RESULTS Risky noise exposure from headphone usage was almost twice as high in wave O1 and O2 (at age 15 or 18) compared with 20-23-year-olds in O3 and O4. Risky exposure to headphones and PLDs were associated with younger age, low and medium education, single-parent household and smoking, whereas good self-rated hearing showed a protective effect. Additionally, not being born in Germany was associated with risky PLD exposure. CONCLUSION Before harmful behaviours become entrenched, starting preventive efforts at a young age is essential.

Abstract
Many young people are potentially at risk of noise-induced hearing loss due to unsafe use of personal listening devices. The aim of this cross-sectional study was to examine the association of sociodemographic factors and risk behavior with unsafe use of personal listening devices in adolescents to identify a target group for prevention. A smartphone application was developed to objectively measure music listening habits among 314 adolescents with a mean age of 13 years and 7 months (SD ±5 months). Listening habits were characterized as safe or unsafe based on the weekly noise dose. Data on sociodemographic factors and traditional health risk behaviors were obtained by questionnaires. Within the study group, 10.5% of the participants exceeded the 50%, and 4.8% the 100% recommended weekly noise dose. Adolescents with a lower socioeconomic status were more likely to engage in unsafe listening habits as compared to adolescents with a higher socioeconomic status. Additionally, risk behavior was associated with higher odds of having unsafe listening habits as compared to no risk behavior. Age, sex and educational levels were not significantly associated with unsafe listening habits. The findings of the present study indicate that interventions to promote safe listening habits should target adolescents with a lower socioeconomic status and higher risk behavior. Future research is needed to investigate how these adolescents can be motivated to adopt safe listening habits.

Abstract
PURPOSE The aim of this study was to analyze the association of total leisure noise exposure and hearing threshold shifts over 5 years among adolescents enrolled in the Ohrkan cohort study. METHOD The Ohrkan cohort of 2,148 students aged 13-19 years was recruited from 2009 to 2011 and followed up 5 years later. Complete baseline and follow-up reports on exposure and outcome were available for 989 participants. Leisure noise exposure was assessed by questionnaires, and clinical audiometric examinations were performed. Two outcomes were defined: occurrence of the Niskar notch pattern and audiometry showing maximum hearing threshold values at 3, 4, and 6 kHz (both ears). Longitudinal analysis using generalized estimating equations was performed. RESULTS High total leisure noise exposure, defined as an energy equivalent of a 40-hr week of > 85 dBA, was estimated for 32.7% of students at baseline and 63.8% at follow-up. A noise notch was observed in 1.1% of adolescents at baseline and 3.3% at follow-up. At baseline, the maximum measured threshold shift was 55 dB, which increased to 85 dB at the follow-up. Longitudinal analysis did not reveal an association between leisure noise exposure and hearing thresholds. Hearing threshold shifts or noise notches were associated with sex, school type, and time point of measurement. CONCLUSIONS No relationship was found between leisure noise and hearing thresholds. Male adolescents and those attending secondary general schools, with graduation following completion of ninth or 10th grade, had a greater likelihood of developing hearing threshold shifts. Prevention programs should focus on these risk groups. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.19233462.

Abstract
OBJECTIVE Investigating determinants of total leisure noise (TLN) exposure among adolescents over 7.5 years and compensating for missing data due to loss to follow-up. DESIGN In the OHRKAN cohort study, data were collected by questionnaires at four waves. TLN was calculated from self-reported duration spent participating in 18 leisure activities. High exposure was defined as exceeding 85 dB(A) of equivalent continuous average sound pressure level (SPL) during a 40-h week. Multiple imputation (MI) and generalised estimating equations (GEE) were used to analyse odds ratios (OR) of determinants of TLN exposure and compared to complete-case analysis. STUDY SAMPLE Closed cohort of 2148 students enrolled in grade 9 of any school in Regensburg (Germany), recruited from 2009 to 2011. RESULTS Up to 74% of adolescents had risky TLN exposure, depending on wave. The most significant sources were discotheques, portable listening devices (PLD) and stereo systems. Higher TLN exposure was associated with time point, education, single-parent households and gender. MI under MAR assumption changed results only slightly compared to complete-case analysis. CONCLUSIONS Prevalence of risky TLN is high during adolescence. MI reinforced trends detected in former results of OHRKAN. Preventive measures should consider the main drivers of noise exposure including changes by age and high risks groups.

Abstract
OBJECTIVES To investigate the association between total leisure noise exposure and intermittent tinnitus among young adults. DESIGN Data were obtained from the Ohrkan study, an ongoing prospective cohort study conducted in South Germany since 2009. Information about exposure to impulse and leisure noise, tinnitus occurrences, sociodemographic variables, and self-rated hearing ability were analysed at four time points over a period of seven and a half years. STUDY SAMPLE Participants of the Ohrkan cohort study, who provided data about the occurrence of tinnitus for all surveys (n = 1028). RESULTS Intermittent tinnitus was reported in the majority of the sample (60%). The risk for intermittent tinnitus increased with higher sound pressure levels from exposure to leisure noise (full model (Odds Ratio, 95%CI): 80-<85dB(A): 1.41 [1.13-1.78], 85-<90dB(A): 1.73 [1.38-2.16], >90dB(A): 2.04 [1.59-2.61]). Visiting nightclubs was a major contributor to this relationship. Of the considered covariables, self-rated hearing as "poor", and growing up in a single-parent household were significantly associated with intermittent tinnitus. CONCLUSION Intermittent tinnitus is very frequent among young adults and is associated with high levels of leisure noise exposure. To prevent intermittent tinnitus, reduced sound pressure levels and the use of hearing protection are necessary.

Abstract
Purpose The aims of this study were to characterize hearing symptoms, habits, and sound pressure levels (SPLs) of personal audio system (PAS) used by young adults; estimate the risk of developing hearing loss and assess whether instructions given to users led to behavioral changes; and propose recommendations for PAS users. Method A cross-sectional study was performed in 50 subjects with normal hearing. Procedures included questionnaire and measurement of PAS SPLs (real ear and manikin) through the users' own headphones and devices while they listened to four songs. After 1 year, 30 subjects answered questions about their usage habits. For the statistical analysis, one-way analysis of variance, Tukey's post hoc test, Lin and Spearman coefficients, the chi-square test, and logistic regression were used. Results Most subjects listened to music every day, usually in noisy environments. Sixty percent of the subjects reported hearing symptoms after using a PAS. Substantial variability in the equivalent music listening level (Leq) was noted (M = 84.7 dBA; min = 65.1 dBA, max = 97.5 dBA). A significant difference was found only in the 4-kHz band when comparing the real-ear and manikin techniques. Based on the Leq, 38% of the individuals exceeded the maximum daily time allowance. Comparison of the subjects according to the maximum allowed daily exposure time revealed a higher number of hearing complaints from people with greater exposure. After 1 year, 43% of the subjects reduced their usage time, and 70% reduced the volume. A volume not exceeding 80% was recommended, and at this volume, the maximum usage time should be 160 min. Conclusions The habit of listening to music at high intensities on a daily basis seems to cause hearing symptoms, even in individuals with normal hearing. The real-ear and manikin techniques produced similar results. Providing instructions on this topic combined with measuring PAS SPLs may be an appropriate strategy for raising the awareness of people who are at risk.

Abstract
This population-based study estimates the prevalence of loud leisure noise exposure and hearing protection usage among Canadians, as well as the population potentially at-risk using an occupational limit of 85 dBA, LEX 40 h, which denotes a typical occupational noise limit for a 40 hour work week. A total of 10 460 participants, aged 6-79 years, completed a Canadian Health Measures Survey household questionnaire. Loud leisure noise was defined by vocal effort required while communicating at arm's length except for loud personal listening device (PLD) usage with earbuds/headphones, which included both volume setting and vocal effort. The most prevalent loud leisure noise activities were amplified music, car/home stereo listening, and power tools, with 40% reporting each source, followed by sporting/entertainment (25%), gasoline engines (23%), and loud PLD listening (19.5%). Loud leisure noise was more prevalent among 12-39 year olds and males. Hearing protection usage was uncommon, from 44.2% (firearms) to 20.3% (power tools) and below 3% during amplified music and sporting/entertainment events. Calculations using self-reported duration of loud leisure noise activities estimated that 6.6 × 106 Canadians were in the high cumulative noise exposure category. A large proportion of Canadians would be expected to develop some degree of noise-induced hearing loss should this pattern persist over years.
