Time to Listen: Most Regular Patrons of Music Venues Prefer Lower Volumes

High sound levels are a feature of nightclubs and live music venues, and therefore pose a risk to patrons’ hearing. As a result, these venues are often a focus area for hearing health promotion, and particular emphasis is placed on motivating patrons to take steps to reduce their noise exposure. In the current study, we approached this issue from a different angle. We asked whether sound levels in music venues accurately reflect the preferences of regular patrons, and examined their attitudes and preferences toward sound levels and protective listening behaviors. The study examined results from 993 regular patrons of nightclubs and live music venues, collected as part of an Australian online hearing health survey. Participants were asked about their participation at the two target venues, experiences of hearing difficulties, and risk perceptions. They were also asked about their preferences in relation to typical venue sound levels and beliefs about other attendees’ preferences. Results showed that while participants generally rated their hearing as good, the majority had experienced hearing difficulties following sound exposure at music venues. The majority of regular patrons were dissatisfied with current sound levels, with around three-quarters of participants reporting preferences below the levels typically experienced at music venues. Participants were generally aware of the risk posed by high sound levels and those who regarded themselves to be at greater risk from attending music venues were more likely to prefer lower sound levels. These findings have important consequences for the development of hearing health initiatives within entertainment venues. Rather than motivating patrons to change their behavior, encouraging venues to meet their patrons’ needs and preferences may be a more successful strategy. Venue operators may find that this approach has a positive impact not only on the hearing health of patrons, but also on the economic health of their venue. Ultimately, reducing the hearing risk in music venues may best be achieved not by telling people what to do, but by listening to what they actually want

Medical practitioners' attitudes to hearing rehabilitation for older adults

Objective: Medical practitioners have the potential to play a significant role in older adults' help seeking behaviour in relation to hearing rehabilitation. The current study aimed to look at attitudinal factors that influence practitioners' decisions to discuss hearing difficulties with older patients and refer them for hearing rehabilitation. Design: A questionnaire based on constructs from the Health Belief Model was used to examine factors that may influence practitioners' referral decisions. Study Sample: One hundred and ten practitioners' attitudes to hearing rehabilitation were examined. Results: The results indicated that practitioners have a high level of awareness about their older patients' susceptibility to hearing loss, and a good understanding of the severity of the associated impacts on older adults' lives. Although practitioners acknowledged the theoretical benefits of hearing rehabilitation, many appear less certain about the potential for actual benefit for their older adults. Barriers to referral include negative perceptions about how older patients prioritise hearing, and patients' ability to afford and adapt to the use of hearing aids. Conclusions: Additional research and education targeted at these area may be beneficial for medical practitioners to increase referral behaviour and improve discussions about hearing rehabilitation with their older patients

Instrumental music teachers : music exposure and hearing loss

Most music teachers experience lengthy periods of noise exposure on a daily basis, which, if of sufficient duration and intensity, can lead to hearing damage, tinnitus, and eventual hearing loss. In this study, 30 music teachers were surveyed regarding their attitudes to music exposure, hearing protection, and symptoms of hearing damage. Pure tone audiograms were obtained for 28 participants. Results showed that teachers were aware of the risks associated with noise exposure, however, they believed that most of their teaching peers and students were less aware. The audiograms revealed reduced hearing acuity in 13 participants: Ten participants had average hearing levels >20-dB HL, and while this was age-appropriate for five participants, the other five had hearing worse than expected for their age. A further three participants had audiograms within the normal range (4FAHL < 20 dB HL), but thresholds were worse than expected for their age. Thus, in at least eight cases, there were possible indications of hearing loss that may be noise-related. This study suggests that music teachers are at greater risk of hearing damage than the general population. We need to inform music teachers of the risk and encourage them to minimise their exposure levels in order to maintain their long-term hearing health.10 page(s

What's in a name? Preschoolers' noun learning performance in relation to their risk for reading disability

This paper reports the findings of an investigation aimed at gaining a clearer understanding of the nature of vocabulary difficulties associated with dyslexia and associated risk status. Three studies were conducted to examine preschoolers' access and mastery of syntactic- and phonological-based processes believed to support word learning. Results are reported for 82 participants whose (reading) risk status was assessed from a composite of measures known to be related to reading development. As expected, risk status correlated positively with participants' ability to recall the phonological form of novel nouns. No relationship was found between risk status and participants' use of syntactic form-class cues in interpreting the noun class of novel names in isolation. However, the ability to use form-class cues was impaired for at-risk participants on a task that required them to learn both the phonological form and noun class. Findings are discussed in relation to the suggestion that limitations in processing resources such as working memory rather than in the availability of language structures may be at the root of the reported poor performance by at-risk children on vocabulary and other linguistic measures

Estimating young Australian adults' risk of hearing damage from selected leisure activities

Objective: Several previous studies have attempted to estimate the risk of noise-induced hearing loss from loud leisure noise. Some of these studies may have overestimated the risk because they used noise estimates taken from the higher end of reported levels. The aim of the present study was to provide a realistic estimate of the number of young Australian adults who may be at risk of hearing damage and eventual hearing loss from leisure-noise exposure. Design: Average noise levels at five high-noise leisure activities, (1) nightclubs; (2) pubs, bars, and registered clubs; (3) fitness classes; (4) live sporting events; (5) concerts and live music venues, were calculated using 108 measurements taken from a large database of leisure noise measurements. In addition, an online survey was administered to a convenience sample of 1000 young adults aged 18 to 35 years, who reported the time spent at these leisure activities and the frequency with which they undertook the activities. They also answered questions about tinnitus and their perceived risk of hearing damage. Although the survey data cannot be considered representative of the population of young Australian adults, it was weighted to this population in respect of age, gender, education, and location. The survey data and the average noise levels were used to estimate each individual’s annual noise exposure, and in turn, estimate those at risk of hearing damage from leisure-noise exposure. Results: For the majority of participants (n = 868), the accumulated leisure noise level was within the acceptable workplace limit. However, 132 participants or 14.1% (population weighted) were exposed to an annual noise dose greater than the acceptable workplace noise limit. By far, the main source of high-risk leisure noise was from nightclubs. Those with more leisure-noise exposure experienced more tinnitus and perceived themselves to be more at risk than those with lower noise exposures. Conclusions: It is recommended that nightclub operators reduce noise levels, display warnings, and provide earplugs for patrons and employees. Health promoters should focus their attention on those young adults who are most at risk and provide them with targeted practical advice about reducing their leisure-noise exposure and avoiding hearing loss.8 page(s

The Objective-subjective assessment of noise : young adults can estimate loudness of events and lifestyle noise

Objective: The aim of the study was to establish whether individuals can subjectively estimate: (1) the loudness of events with respect to the objectively measured noise level; and (2) the overall loudness of their daily noise exposure level. Design: Participants wore personal noise exposure meters for up to five days. During this time, participants kept diaries of daily events and estimated the loudness of these events and their overall noise exposure using 1-to-10 rating scales. Study sample: A group of 45 volunteers aged between 18 and 35 years participated in the study. Results: 86% of participants’ subjective estimates were significantly correlated with the objective noise measurements. Multiple regression showed that age, overall lifestyle noise, and diary quality were predictors of the strength of correlation observed. In addition participants’ subjective estimates of their overall noise exposure were significantly correlated with their actual average daily noise exposure. Conclusions: Results suggest that individuals can make a reasonable estimate of the loudness of events they experience and the overall level of noise they experience. These results may have significant influence for those interested in producing effective hearing health awareness programs in that individuals may be capable of assessing their own degree of hazard exposure.6 page(s

Noise exposure in the balance : managing occupational and leisure risks to hearing health

Health and safety risks that are present in both occupational and home/leisure environments can pose difficulties for health and safety professionals when determining risk mitigation responsibilities. Where work is defined as the time spent in paid employment (usually at a specified location), risks or costs associated with activities undertaken on “work time”, are thought to be the responsibility of the employer. Leisure, defined as time free from work commitments, is under the control of the individual, and associated risks may be considered the individual’s responsibility.6 page(s

A Snapshot of young adults' noise exposure reveals evidence of 'binge listening'

There have been several previous studies into daily noise exposure levels in modern urban communities, which typically report mean noise exposure levels (L sub(Aeq)) for adults between 73 and 79 dB. In this study, rather than focus on group mean exposures across a wide age range, individual patterns of noise exposure over 4- and 5-day periods were examined in a group of 45 young adults aged 18-35 years. The main objective of the study was to determine the extent to which young adults exhibit a 'binge listening' pattern of noise exposure, i.e., high weekend leisure noise vs. low weekday work noise exposure. A secondary objective was to identify the types of activities that generate the highest noise exposures. The results showed that although most participants (60%) were exposed to low daily noise levels, 33% of participants exhibited a 'binge listening' exposure pattern characterized by one or two high-noise days, usually a Friday, Saturday or Sunday, preceded or followed by much quieter days. The most notable high-noise activities were playing an instrument solo or in a band; attending a nightclub; and attending a pop concert, each of which recorded average noise levels greater than the chronic exposure presupposed in traditional risk models, however, under the equal-energy principle, repeated 'binge' noise exposures from weekend visits to nightclubs, live music events and other high-noise represent a significant risk to long-term hearing health.5 page(s

Providing earplugs to young adults at risk encourages protective behaviour in music venues

For some young people, nightclubs and other music venues are a major source of noise exposure, arising from a combination of very high noise levels; relatively long attendance duration; and frequent, sustained participation over several years. Responsibility for hearing protection is largely left to individuals, many of whom choose not to wear earplugs. In order to encourage earplug use in these settings, a new approach is needed. The aim of the study was to examine whether presentation of hearing health information would result in increased use of earplugs, or whether provision of earplugs alone would be sufficient to change behaviour. A total of 51 regular patrons of music venues were allocated to either a low-information (lo-info) or high-information (hi-info) group. Both groups completed a survey about their current noise exposure, earplug usage and perceived risk of hearing damage. Both groups were also provided with one-size-fits-all filtered music earplugs. The hi-info group was also provided with audio-visual and written information about the risks of excessive noise exposure. After 4 weeks, and again after an additional 12 weeks, participants were asked about their recent earplug usage, intention to use earplugs in the future, and perceived risk of hearing damage. The results showed that after 4 weeks, the hi-info group’s perceived personal risk of hearing damage was significantly higher than that of the lo-info group. After 16 weeks, these differences were no longer evident; however, at both 4 and 16 weeks, both the lo- and hi-info groups were using the earplugs equally often; and both groups intended to use earplugs significantly more often in the future. This suggests that the information was unnecessary to motivate behavioural change. Rather, the simple act of providing access to earplugs appears to have effectively encouraged young at-risk adults to increase their earplug use.12 page(s
