Intentional Exposure to Loud Music: The Second MTV.com Survey Reveals an Opportunity to Educate
ABSTRACT Music-induced hearing loss (MIHL), an unconsciously self-inflicted public health concern, could evolve into an epidemic because of the appeal of loud music. After media attention about a previous hearing-loss survey with Music Television (MTV.com), we hypothesized that a repeat survey could compare awareness and behavior trends.
We incorporated the 2002 survey into the new 73-question instrument presented to random visitors on the MTV.com website in 2007. A P < .05 value was used for independent t and z- tests.
A total of 2500 completed surveys were analyzed. Hearing loss was considered a problem by 32% of respondents compared with other health issues such as drug/alcohol use (62%). However, nearly half of the respondents admitted experiencing symptoms such as tinnitus or hearing loss after loud music exposure. Health care providers were the least likely source of MIHL awareness despite the respondents favoring provider education for hearing protection behavior modification.
Most respondents still could not recall learning about prevention of potential hearing loss, although the media has become the most informative source. Most respondents indicated that they would adopt protective ear behavior if made aware of hearing loss risk, especially if informed by health care professionals, revealing an educational opportunity.

ABSTRACT: During leisure activities young people are often exposed to excessive noise levels resulting in an increase of noise-induced symptoms such as hearing loss, tinnitus and hyperacusis. Noise-induced tinnitus is often perceived after loud music exposure and provides an important marker for overexposure as a temporary threshold shift that is often not experienced by the individual itself. As oxidative stress plays an important role in the pathogenesis of noise-induced hearing loss, the use of antioxidants to prevent hearing damage has recently become the subject of research. This study proposes a randomized, double-blind, placebo-controlled crossover trial to assess the effects of a prophylactic combination of N-acetylcysteine (600 mg) and magnesium (200 mg) prior to leisure noise exposure in young adults. The primary outcome measure is the tinnitus loudness scored by a visual analogue scale (VAS). Secondary outcome measures are the differences in audiological measurements for the antioxidant treatments compared to placebo intake. Audiological testing comprising of pure tone audiometry including frequencies up to 16 kHz, distortion product otoacoustic emissions, transient-evoked otoacoustic emissions and speech-in-noise testing will be performed prior to and within 7 hours after noise exposure. By use of a mixed effects statistical model, the effects of antioxidants compared to placebo intake will be assessed. As adolescents and young adults often do not use hearing protection while being exposed to loud music, the use of preventive antioxidant intake may provide a useful and harmless way to prevent noise-induced hearing damage in this population. Furthermore, when exposed to hazardous noise levels the protection provided by hearing protectors might not be sufficient to prevent hearing damage and antioxidants may provide additive otoprotective effects. Previous research mainly focused on occupational noise exposure. The present study provides a protocol to assess the usefulness of antioxidants during leisure noise activities.Trial registration: The present protocol is registered at ClinicalTrials.gov: NCT01727492.Trials 04/2014; 15(1):110.

ABSTRACT: Many studies have documented a high incidence of hearing loss and tinnitus in adolescents after recreational noise exposure. The prevalence of noise-induced symptoms is in contradiction to the low preventive use of hearing protection. The effects of preventive campaigns on the attitudes toward noise in young people are under debate. The aim of the present study is to investigate whether a preventive campaign can alter attitudes toward noise in adolescents and whether this results in an increase of hearing protection use in this population.International journal of pediatric otorhinolaryngology 04/2014; 78(4).

ABSTRACT: PURPOSE This study examined listening levels and duration of portable listening devices (PLDs) used by people with diversity of ethnicity, education, music genre, and PLD manufacturer. The goal was to estimate participants' PLD noise exposure and identify factors influencing user behavior. METHOD This study measured listening levels of 160 adults in two New York City locations: (a) a quiet college campus and (b) Union Square, a busy interchange. Participants completed a questionnaire regarding demographics and PLD use. Ordinary least squares (OLS) regression was used to explore the significance of demographic and behavioral factors. RESULTS Average listening level was 94.1 dBA, with 99/160 (61.9%) and 92/159 (57.5%) exceeding daily (LA8hn) and weekly (LAwkn) recommended exposure limit, respectively. African American participants listened at the highest average levels (99.8 dBA). CONCLUSIONS A majority of PLD users exceeded recommended exposure levels. Factors significant for higher exposure were ethnicity and age; factors not significantly associated with exposure were gender, education, location, awareness of possible association between PLD use and noise-induced hearing loss, mode of transportation, device manufacturer, and music genre. Efforts to effect behavior changes to lessen noise-induced hearing loss risk from PLD use should be sensitive to the cultural differences within the targeted population.Journal of Speech Language and Hearing Research 02/2014; 57(4).
