Hearing Health

Background: The popularity of personal listening devices (PLDs) including iPods has increased dramatically over the past decade. PLDs allow users to listen to music uninterrupted for prolonged periods and at levels that may pose a risk for hearing loss in some listeners, particularly those using earbud earphones that fail to attenuate high ambient noise levels and necessitate increasing volume for acoustic enjoyment. Earlier studies have documented PLD use by teenagers and adults, but omitted college students, which represent a large segment of individuals who use these devices. Purpose: This study surveyed college students' knowledge about, experiences with, attitudes toward, and practices and preferences for hearing health and use of iPods and/or other PLDs. The study was designed to help determine the need, content, and preferred format for educational outreach campaigns regarding safe iPod use to college students. Research Design: An 83-item questionnaire was designed and used to survey college students' knowledge about, experiences with, attitudes toward, and practices/preferences for hearing health and PLD use. The questionnaire assessed Demographics and Knowledge of Hearing Health, iPod Users' Practices and Preferences, Attitudes toward iPod Use, and Reasons for iPod Use. Results: Generally, most college students were knowledgeable about hearing health but could use information about signs of and how to prevent hearing loss. Two-thirds of these students used iPods, but not at levels or for durations that should pose excessive risks for hearing loss when listening in quiet environments. However, most iPod users could be at risk for hearing loss given a combination of common practices. Conclusions: Most of these college students should not be at great risk of hearing loss from their iPods when used conscientiously. Some concern is warranted for a small segment of these students who seemed to be most at risk because they listened to their iPods at high volume levels for long durations using earbuds, and reported that they may already have hearing loss due to their iPods.

Patients At Risk

Ototoxicity refers to the hearing impairment that results from the temporary or permanent inner ear dysfunction after treatment with an ototoxic drug. Other drug classes known to have ototoxic properties include aminoglycosides, loop diuretics, quinine, nonsteroidal anti-inflammatory drugs, and antiretroviral therapy. Platinum-based chemotherapy drugs are effective drugs used to treat many types of malignant neoplasms. However, its ototoxic potential puts cancer patients at risk of hearing loss. This, in turn, negatively affects the patient’s quality of life. It is essential for clinicians working with these patients to be aware of the ototoxic properties of platinum preparations and the clinical signs in order to identify patients at risk of developing hearing loss. The review identified peer-reviewed articles available from January 1975 to July 2019 on the monitoring of cytotopic toxicity and ototoxicity associated with cisplatin, and included only articles in English. The same researcher conducted a literature search and reviewed abstracts and articles for inclusion in the study. The studies were identified using a MeSH (Medical Subject Headings) keyword and term search in electronic databases. A manual search for relevant authors and journals was also completed. The links cited by each publication, review, or book chapter were reviewed to find additional potential publications. This article provides an updated review of the ototoxicity associated with platinum-based chemotherapy drugs.

Exposure Levels

Current legislation and threshold limits for occupational noise exposure may not sufficiently account for higher vulnerability of the foetus. We conducted a systematic literature review and identified 20 relevant studies of prenatal noise exposure levels and health. Maternal tissues attenuate industrial noise by about 30 dB. The foetus responds the earliest to noise exposure from the 19th week of gestational age. There is some evidence of an increased risk of hearing loss at prenatal noise levels≥85 dBA (8 hour average) and little evidence at lower levels. Increased risks for preterm birth, small-for-gestational-age and congenital malformations are seen as single study findings at levels≥90 dBA. There is little evidence for how noise exposure may increase the risk of extra-auditive effects in the foetus. Methodological shortcomings and the scarce number of studies limit the conclusions that can be drawn. Still, we recommend pregnant women avoid working at noise levels≥85 dBA.

Brainstem Response

Background: The primary aim of newborn hearing screening is to detect permanent hearing loss. Because otoacoustic emissions (OAEs) and automated auditory brainstem response (AABR) are sensitive to hearing loss, they are often used as screening tools. On the other hand, false-positive results are most often because of transient outer- and middle ear conditions. Wideband acoustic immittance (WAI), which includes physical measures known as reflectance and absorbance, has shown potential for accurate assessment of middle ear function in young infants.Objective: The main objective of this study was to determine the feasibility of WAI as a diagnostic tool for assessing middle ear functioning in preterm neonates in the neonatal intensive care unit (NICU) designed for premature and ill neonates. A further objective was to indicate the difference between the reflectance values of tones and click stimuli.Method: Fifty-six at-risk neonates (30 male and 26 female), with a mean age at testing of 35.6 weeks (range: 32–37 weeks) and a standard deviation of 1.6 from three private hospitals, who passed both the distortion product otoacoustic emission (DPOAE) and AABR tests, were evaluated prior to discharge from the NICU. Neonates who presented with abnormal DPOAE and AABR results were excluded from the study. WAI was measured by using chirp and tone stimuli. In addition to reflectance, the reflectance area index (RAI) values were calculated.Results: Both tone and chirp stimuli indicated high-power reflectance values below a frequency of 1.5 kHz. Median reflectance reached a minimum of 0.67 at 1 kHz – 2 kHz but increased to 0.7 below 1 kHz and 0.72 above 2 kHz for the tone stimuli. For chirp stimuli, the median reflectance reached a minimum of 0.51 at 1 kHz – 2 kHz but increased to 0.68 below 1 kHz and decreased to 0.5 above 2 kHz. A comparison between the present study and previous studies on WAI indicated a substantial variability across all frequency ranges.Conclusion: These WAI measurements conducted on at-risk preterm NICU neonates (mean age at testing: 35.6 weeks, range: 32–37 weeks) identified WAI patterns not previously reported in the literature. High reflective values were obtained across all frequency ranges. The age of the neonates when tested might have influenced the results. The neonates included in the present study were very young preterm neonates compared to the ages of neonates in previous studies. WAI measured in at-risk preterm neonates in the NICU was variable with environmental and internal noise influences. Transient conditions affecting the sound-conduction pathway might have influenced the results. Additional research is required to investigate WAI testing in ears with and without middle ear dysfunction. The findings of the current study imply that in preterm neonates it was not possible to determine the feasibility of WAI as a diagnostic tool to differentiate between ears with and without middle ear pathology.

Industrial Health

Vocal cord dysfunction has a definite incidence of association with high environmental noise levels. Our study has shown roughly an 8% incidence of vocal cord dysfunction (vocal cord nodules, vocal cord polyps and chronic laryngitis) in individuals working in high noise environments. In addition, those individuals who have surgery for vocal cord nodules and who work in high noise environments will have over a 30% incidence of recurrent vocal cord dysfunction following surgery. Our study indicates that females tend to be more at risk in high noise environments than males.

High Incidence

A high incidence of hearing loss has been encountered among tractor drivers, and noise levels are shown to be further increased by the addition of cabs, particularly those which are structurally strong to resist crushing if the vehicle overturns. Some reductions in the noise level of the operator's environment can be obtained by covering the engine or by exhaust system modifications, while possible future improvements to diesel engine design may effect a significant improvement. However, it is proposed that noise reduction is likely to be achieved by attention to acoustic features of the operator's cab. The inclusion of resilient mounts, substantial floors and bulkheads, and acoustically absorbent linings are all shown to provide worthwhile improvements and, in combination, these measures can reduce noise levels from more than 100 dBA to 90 dBA or less. Where the tractor is fitted with a safety frame only, a low noise fabric cladding is shown to be feasible.
