Identifying Targets for Interventions to Increase Uptake and Use of Hearing Protection in Noisy Recreational Settings

Interventions to increase hearing protection behaviours within noisy recreational settings are limited by the lack of an underpinning evidence base. The aim of the present study was to identify targets for interventions in a population exposed to recreational noise, including those who had used hearing protection (ever-performers) versus those who had not (never-performers). A cross-sectional survey was administered to 185 UK adults who had been involved in noisy recreational activities. Participants had an average age of 36.79 years; the majority were women (68.1%), from a white ethnic background (87.6%), and with non-manual occupations (75.7%). Using Chi-square, MANOVA and ANOVA, we looked for differences in sociodemographic variables and variables from the capabilities, opportunities and motivations model of behaviour change (COM-B) between ever- and never-performers. Ever-performers were more likely to be younger (p < 0.050), men (p < 0.050), and in a manual occupation (p < 0.050) compared to never-performers. Although the two groups felt capable and reported similar opportunities to use hearing protection, never-performers lacked automatic motivation (p < 0.001) and reflective motivation (p < 0.001) compared to ever-performers. For the first time, the present study identifies potential groups at whom hearing protection interventions might be targeted and what those interventions may contain. Further work is required to develop interventions targeted at older people, women and those in non-manual occupations. Lack of motivation is a key concern, and further work that uses specific theoretical frameworks, such as the PRIME (Plans, Responses, Impulses, Motives, and Evaluations) theory of motivation, may shed light on the kinds of interventions that are needed to boost hearing protection use effectively.

In dubio pro silentio - Even Loud Music Does Not Facilitate Strenuous Ergometer Exercise

Background: Music listening is wide-spread in amateur sports. Ergometer exercise is one such activity which is often performed with loud music.

Aim and Hypotheses: We investigated the effects of electronic music at different intensity levels on ergometer performance (physical performance, force on the pedal, pedaling frequency), perceived fatigue and heart rate in healthy adults. We assumed that higher sound intensity levels are associated with greater ergometer performance and less perceived effort, particularly for untrained individuals.

Methods: Groups of high trained and low trained healthy males (N = 40; age = 25.25 years; SD = 3.89 years) were tested individually on an ergometer while electronic dance music was played at 0, 65, 75, and 85 dB. Participants assessed their music experience during the experiment.

Results: Majorities of participants rated the music as not too loud (65%), motivating (77.50%), appropriate for this sports exercise (90%), and having the right tempo (67.50%). Participants noticed changes in the acoustical environment with increasing intensity levels, but no further effects on any of the physical or other subjective measures were found for neither of the groups. Therefore, the main hypothesis must be rejected.

Discussion: These findings suggest that high loudness levels do not positively influence ergometer performance. The high acceptance of loud music and perceived appropriateness could be based on erroneous beliefs or stereotypes. Reasons for the widespread use of loud music in fitness sports needs further investigation. Reducing loudness during fitness exercise may not compromise physical performance or perceived effort.
