Personal listening devices (PLDs) have the potential to increase the risk of noise-induced hearing loss (NIHL) for users. The present study aimed to investigate the nature and extent of the risk posed, by describing the user profile of a PLD population, identifying listening habits of that population, and examining whether PLD risk status is associated with hearing damage. A sample of 4,185 Australian PLD users completed an online survey about listening behaviors and hearing health. Listeners were characterized as low, high, or very high-risk based on daily noise dose estimates calculated from self-reported listening volume and durations. Listening patterns and hearing difficulties were examined in relation to risk status. Results indicated differences in listening volumes and durations with respect to age, with higher listening volumes reported for environments with greater background noise. Fifteen percent of participants' usage was classified as posing a potential risk to hearing, with a significantly greater proportion of younger people in higher-risk categories. Forty-one percent of participants reported feeling they have a hearing loss, with ∼20% reporting difficulties with speech in noise. For 18- to 35-year-olds, higher-risk status was associated with a greater proportion of self-reported hearing difficulties, including perceived poorer speech perception. These results have implications for hearing health promotion activities and suggest that messages should focus on either volume levels or durations depending on the particular activity in which the PLD is used. In addition, the results underline the importance of placing PLD exposure in the context of individuals' wider noise exposure. Although PLD use alone is not placing the majority of users at risk, it may be increasing the likelihood that individuals' cumulative noise exposure will exceed safe levels.

The Impact

AIM: To investigate the impact of tinnitus on professional musicians in the UK. BACKGROUND: Tinnitus is the experience of sound when an external source is absent, primarily associated with the ageing process, hearing loss, and noise exposure. Amongst populations exposed to industrial noise, noise exposure and noise-induced hearing loss (NIHL) have been found to be the factors most associated with tinnitus. The risk of NIHL amongst professional musicians is greater than that amongst the general population, meaning they may be at increased risk of tinnitus. METHODS: Seventy-four professional musicians completed an online survey involving closed and open-ended questions, and completed the Tinnitus fuctional Index (TFI) questionnaire. Descriptive statistics and thematic analysis of open-ended qualitative responses were used to analyse the data. RESULTS: Three themes were generated from the analysis of the responses to the open-ended questions. These themes were: (1) the impact of tinnitus on the lives of professional musicians, (2) professional musician experience of tinnitus services, support, and hearing health and safety, and (3) the support professional musicians want. The mean global TFI score for professional musicians was 39.05, interpreted as tinnitus being a moderate problem. Comparisons with general population data revealed lower TFI scores for the TFI subscales of ‘sense of control’ and ‘intrusiveness’ for professional musicians and higher for auditory difficulties associated with tinnitus amongst professional musicians. CONCLUSION: Tinnitus can negatively impact on professional musicians’ lives. There is a need for bespoke self-help groups, awareness raising, and education to prevent tinnitus and promote hearing health among musicians.

SUMMARYListeners with sensorineural hearing loss (SNHL) struggle to understand speech, especially in noise, despite audibility compensation. These real-world suprathreshold deficits are hypothesized to arise from degraded frequency tuning and reduced temporal-coding precision; however, peripheral neurophysiological studies testing these hypotheses have been largely limited to in-quiet artificial vowels. Here, we measured single auditory-nerve-fiber responses to a natural speech sentence in noise from anesthetized chinchillas with normal hearing (NH) or noise-induced hearing loss (NIHL). Our results demonstrate that temporal precision was not degraded, and broader tuning was not the major factor affecting peripheral coding of natural speech in noise. Rather, the loss of cochlear tonotopy, a hallmark of normal hearing, had the most significant effects (both on vowels and consonants). Because distorted tonotopy varies in degree across etiologies (e.g., noise exposure, age), these results have important implications for understanding and treating individual differences in speech perception for people suffering from SNHL.

ObjectiveThis study investigated risk factors for poor earplug fit, with a focus on the association between hearing loss and personal attenuation ratings (PARs).MethodsEarplug fit was assessed by obtaining PARs using a real ear at attenuation threshold (REAT) system. Hearing loss was assessed using the unoccluded hearing thresholds measured during the REAT testing and the results of a speech-in-noise test. Potential predictors of PARs were modelled using both simple and multiple linear regression. Hearing loss was the primary predictor of interest.ResultsData were collected from 200 workers at ten above-ground mining sites in the Midwestern USA. Workers reported wearing their hearing protection on average 73.9% of the time in a high noise environment (mean 8-hour time-weighted average noise exposure 85.5 dBA, range 65–103 dBA). One-quarter (26.7%) of workers were found to have a hearing loss (hearing threshold ≥25 dB across 1–4 kHz), and 42% reported symptoms of tinnitus. Workers with a hearing loss had a significantly lower PAR than those without a hearing loss (β=−5.1, SE=1.7).ConclusionsThe results of the adjusted regression models suggest that workers with hearing loss achieved significantly lower PARs than those without hearing loss. This association between hearing loss and hearing protection devices (HPD) fit brings into focus the potential benefit of fit checks to be included in hearing conservation programmes. Workers found to have hearing loss should be prioritised for fit testing, as their hearing impairment may be associated with poor HPD fit.

Purpose A need exists to investigate the short- and long-term impact of noise exposures during and following military service on auditory health. Currently available questionnaires are limited in their ability to meet this need because of (a) inability to evaluate noise exposures beyond a limited time frame, (b) lack of consensus on scoring, (c) inability to assess impulse exposures (e.g., firearm use), (d) lack of a single questionnaire that assesses both military and nonmilitary exposures, and (e) lack of validity and reliability data. To address these limitations, the Lifetime Exposure to Noise and Solvents Questionnaire (LENS-Q) was developed. The purpose of this report is to describe the development and initial validation of the LENS-Q as a measure of self-reported noise exposure. Method Six hundred ninety participants, consisting of current Service members and recently military-separated (within about 2.5 years) Veterans, completed the LENS-Q, additional study questionnaires, and comprehensive audiometric testing. Noise exposure scores were computed from LENS-Q responses using a simple scoring algorithm that distinguishes between different cumulative levels of exposure and allows for the inclusion of both continuous and impulse noise exposures. Results The LENS-Q demonstrates good construct validity as evidenced by measures of hearing loss, tinnitus, and subjective hearing difficulties all increasing with an increase in noise exposure scores. A logistic regression, adjusting for age and sex, revealed that participants in the highest exposure group were 2.4–3.9 times more likely to experience hearing loss, 2.7–2.8 times more likely to experience tinnitus, and 3.0–3.7 times more likely to report hearing difficulties compared with individuals in the lowest exposure group. Conclusions The LENS-Q captures noise exposure over an individual's lifetime and provides an alternative scoring metric capable of representing exposure to both continuous and impulse noise. Findings suggest that the LENS-Q is a valuable tool for capturing and measuring both military and nonmilitary noise exposure. Supplemental Material https://doi.org/10.23641/asha.14582937

Introduction: Noise-induced hearing loss (NIHL) is a common occupational disease that represents an irreversible hearing damage to the auditory system. It has been identified as a complicated disease involving both environmental and genetic factors. More efforts need to be made to explore the genes associated with susceptibility to NIHL. The main aim of this research is to detect the associations between SIK3 polymorphisms and NIHL susceptibility in Han people in China. Methods: A case-control study was performed in 586 cases and 639 controls in a textile factory matched for sex, age, smoking, drinking, work time with noise, and intensity of noise exposure. Three single nucleotide polymorphisms (SNPs) (rs493134, rs6589574, and rs7121898) of SIK3 were genotyped in the participants. Then, the main influences of the SNPs on and their interactions with NIHL were assessed. Results: Under the allelic model, distributions of rs493134 T, rs6589574 G, and rs7121898 A in the NIHL group are statistically different from those of the normal group (p = 0.001, p < 0.001, and p = 0.019, respectively). The following haplotype analysis shows that TAA (rs493134-rs6589574-rs7121898) may have a protective effect, while TGA (rs493134-rs6589574-rs7121898) (OR = 1.49, 95% CI = 1.25–1.79) may be a risk factor for NIHL. Multifactor dimensionality reduction analysis shows that the interaction of the 3 selected SNPs is associated with NIHL susceptibility (OR = 1.88, 95% CI = 1.50–2.36). Conclusion: The results suggest that 3 SNPs (rs493134, rs6589574, and rs7121898) of SIK3 may be an important part of NIHL susceptibility and can be applied in the prevention, early diagnosis, and treatment of NIHL in noise-exposed Chinese workers.

Purpose: To determine how amplified earmuffs affect the intelligibility of speech in noise for people with hearing loss, and to determine how various brands of amplified earmuffs compare in terms of speech intelligibility and electroacoustic response. Method: The Hearing in Noise Test (HINT) was used to measure the intelligibility of speech for 10 participants with hearing loss when they listened in a background of recorded industrial noise at 85 dBA. Participants listened with 3 different sets of amplified earmuffs (Peltor Tactical 7-S, Elvex COM 55, and Bilsom 707 Impact II), with a set of passive earmuffs (E-A-R Ultra 9000), and with ears unoccluded. Two measurements of sentence threshold were obtained under each of the 5 listening conditions. Gain was measured electroacoustically across a range of input levels and frequencies for each amplified earmuff. Results: Electroacoustic measurements indicated that each electronic earmuff amplified at low input levels and attenuated at high input levels. However, gain characteristics varied greatly across devices. HINT sentence thresholds were not significantly different across the 5 listening conditions or across the 2 trials. Conclusion: Results suggest that each type of earmuff can be used to reduce the noise exposure of people with hearing loss without compromising their ability to understand speech.

Relevant Outcome

Traditional hearing conservation programs are based on the premise that noise dose, as measured by the time-weighted average noise level, is the primary risk factor associated with occupational hearing loss and that permanent threshold shifts are the most relevant outcome measures for determining when a noise-related hearing loss has occurred. However, recent studies in animal models have suggested that significant neurological damage to the hearing system can occur from noise exposures even when they are not severe enough to result in permanent threshold shifts. This has led to a number of studies attempting to relate subjective measures of noise exposure to subjective measures of hearing difficulty and suprathreshold measures of hearing performance (e.g., speech-in-noise tests). In this study, 3,330 U.S. service members volunteered to complete a survey on noise exposure, subjective hearing complaints, and tinnitus in conjunction with their annual hearing tests. Two questions were also included about the frequency and duration of temporary hearing losses that may have been experienced by the service member. The results show that subjective reports of temporary threshold shifts were substantially more predictive of tinnitus and other hearing complaints than more traditional questions based on the frequency of noise exposure.

Musical instruments and singers' voices can reach high sound pressure values representing a risk to hearing health, which is of particular relevance for music teachers. Therefore, the potential risk of hearing damage among music teachers in a university school of music was assessed. Twenty teachers completed all phases of the study. Sound pressure levels were measured with a sound meter and daily noise exposure levels were computed and compared with legal reference values in force. Three types of hearing exams were administered to all teachers by health technicians. Most teachers (75%) were subjected to daily noise exposure levels below 80 dB(A). Teaching to play brass instruments appears to be the most risky activity. Only three subjects were diagnosed with noise-induced hearing loss, which cannot be exclusively ascribed to occupational activities because they are involved in extracurricular activities. Increased sample size and the use of noise dosimetry would have improved the study conclusions.

AbstractAlbeit limited, research suggests that students pursuing careers in health care receive limited training on the provision of services for people with hearing loss. As the incidence of hearing loss continues to increase among Americans, it is critical that medical professionals understand how hearing loss among patients may affect the manner in which they can provide services most effectively.The aim of this project is to assess the amount of experience and confidence that preprofessional health-care students at one university obtain during the course of their training and whether these students would be interested in additional information related to hearing health.Preprofessional health-care students in terminal degree programs at one university completed a survey regarding the provision of services for individuals with hearing loss. Students were asked to quantify their prior training on topics related to hearing loss, report their perceptions of the benefits and barriers to screening hearing, and report their self-efficacy in providing services for individuals with hearing loss. Additional survey items investigated students’ interest in receiving further training on these topics.Participants (n = 95; 16.2% response rate) were students at a mid-sized, Midwestern university who were pursuing the following terminal degrees: medicine, physician assistant, nursing, pharmacy, physical therapy, occupational therapy, speech-language pathology, and respiratory therapy (bachelor’s degree in respiratory care). Participants were selected based on membership in an interdisciplinary education training program. All students in this program received an invitation to participate in the study. Of the participants, 68 (71.6%) were Caucasian and 86 (90.5%) were female.A 28-item online survey on various topics related to hearing loss was used to document student responses. All students enrolled in a university’s interdisciplinary professional education course (n = 586) received an online link to the survey via an initial email, which contained a brief introduction to the study, the assurance of response anonymity, and a statement regarding implied consent. A second email was sent to students, which reminded participants of the request to complete the survey.Overall, 60% of participants reported an interest in receiving additional information on hearing health and 66.3% of respondents indicated that they wished to receive training via an in-service or internet workshop facilitated by their university program. Most of the participants reported that they had not received training and did not feel confident identifying the signs and symptoms of hearing loss and making an appropriate referral, which led to the request for additional information.The results of this study suggest that preprofessional health-care students have an interest in receiving additional education on various topics related to hearing loss including a better understanding of how hearing loss impacts the quality of life in affected individuals. These findings provide an incentive to provide additional training related to hearing loss identification and management for preprofessional health-care students to foster increased competency and improved patient care.

Introduction Noise-induced hearing loss (NIHL) is a serious problem for workers and therefore for businesses. The hearing conservation program (HCP) is a set of coordinated measures to prevent the development or evolution of occupational hearing loss, which involves a continuous and dynamic process of implementation of hearing conservation routines through anticipation, recognition, evaluation, and subsequent control of the occurrence of existing environmental risks or of those that may exist in the workplace and lead to workers' hearing damage. Objective The aim of this study was to evaluate the effectiveness of the HCP in preventing further hearing loss in workers with audiograms suggestive of NIHL. The audiometric tests and medical records of 28 furniture company workers exposed to noise were reviewed and monitored for 2 years. Methods This retrospective, cross-sectional study examined five audiometric tests in the medical records (on admission and every semester) of 28 workers in a furniture company (totaling 140 audiometric exams) following the introduction of the HCP. Results Data analysis showed no differences between the audiometric tests conducted on admission and those performed every semester. Conclusions The HCP implemented was effective in preventing the worsening of hearing loss in workers already with NIHL when exposed to occupational noise. Therefore, such a measure could be useful for the employment of workers with hearing loss in job sectors that have noise exposure.
