¸ñÀû: Noise-induced hearing loss is uniquely preventable. Hands-free devices
typically operate between 94-110 decibels at high volumes, despite
sounds above 70 decibels considered harmful. The rampant abuse of
hands-free devices raises concern as a risk factor for premature
hearing loss. Once considered an occupational health disorder, now
threatens to become a widespread public health concern, akin to the
'common cold' of the future. ¹æ¹ý:A two-part survey was circulated amongst young individuals, part 1
including consent form, biodata, existing health conditions, smoking
status, details of hands free usage habit and awareness on the topic.
Second part was the Self-test for hearing loss questionnaire by
American Speech-Language-Hearing Association for hearing evaluation.
Data was analysed using JMP, Version 13, p<0.05 considered significant. °á°ú:We surveyed 2297 young individuals (mean age: 21.4 2.2 years, 55.4%
female) to assess hearing loss and the use of hands-free devices. The
majority of participants (60.4%) reported regular use of hands-free
devices. The mean score on the hearing loss questionnaire was 3.99
1.8, indicating a moderate level of hearing impairment.
A significant association was found between regular hands-free use and
greater hearing loss by Mann-Whitney test (p=0.01), with users of
earphones at higher volumes experiencing more severe hearing loss (p<
0.01). Participants who used earphones at higher volumes (p< 0.01) or
increased the volume during (p< 0.01) use showed greater hearing
impairment. Those who agreed that earphones could negatively impact
hearing had lower degrees of hearing loss (p< 0.01). However, awareness
of good hearing practices was not significantly associated with hearing
loss (p=0.15). °á·Ð:To ensure minimal damage, new technology must be introduced which
controls the noise level within appropriate limits. Mass education of
the public on the proper standard operating procedures of hands free
use as currently recommended by the World Health Organization may also
help reduce the potential burden of NIHL in the future. |
