High-frequency profile in adolescents and its relationship with the use of personal stereo devices

Abstract

The prevalence of harmful sound habits due to the use of personal stereo devices is high in the adolescent population, but there was no correlation between exposure to high sound pressure levels through personal stereos and the high-frequency thresholds in this population.

Limiares de audibilidade de altas frequências em indivíduos adultos normo-ouvintes

“…Analysis of the auditory sensitivity at high frequencies in 125 adolescents aged 12-17 years with harmful hearing habits (use of MP3 player) demonstrated no correlation between use of MP3 player and auditory thresholds, and a division into 12-14 and 15-17-year age groups showed an increased mean for higher thresholds in the group composed of older individuals for all frequencies tested, except for 11,200 Hz (18) . Although characterization of high-frequency thresholds by age group in adolescence shows worse responses in the older age group (23,24) , there is no agreement on the exact period that this reduction begins (25,26) .…”

“…A survey that analyzed the difference between high-frequency hearing thresholds in 14 individuals aged 19-56 years with a complaint of tinnitus, found no statistically significant difference between the right and left ears, as well as regarding location of the tinnitus complaint (4) . Another research with the objective of analyzing and correlating the audiometric findings at the 9-16 kHz frequencies in 125 adolescents with harmful hearing habits verified neither difference between the ears, nor influence at high frequencies due to exposure to high sound pressure levels (18) . A study that evaluated whether there were differences between the ears in 74 individuals aged 18-30 years without auditory complaints, found no statistically significant difference between hearing thresholds (6) .…”

Audiometric notch and extended high-frequency hearing threshold shift in relation to total leisure noise exposure: An exploratory analysis

“…Most reported significant results,[ 15 22 23 24 27 38 39 40 ] whereas only a few studies showed no relationship between leisure noise and extended high-frequency hearing threshold shift. [ 25 26 41 ] Compared to the previous studies, our study had obvious strength. First, most previous studies only focused on one or a few leisure time activities such as PLDs, nightclub or discotheque visiting, instrument playing, and so on, whereas our survey considered comprehensively a wide range of leisure time activities to estimate the total leisure noise exposure as realistic as possible.…”

“…[ 22 23 24 ] reported significant differences of hearing thresholds between people exposed to PLD or not at most high frequencies, whereas Silvestre et al . [ 25 ] reported no associations between exposure to personal stereo devices and hearing threshold shift at all high frequencies. One explanation for the inconsistent results may be that these studies only considered one leisure time activity without accounting for many other activities.…”

Acuidade Auditiva Em Altas Frequências E Contaminação Microbiana Dos Plugs De Ouvido Em Estudantes Universitários

“…O advento da música amplificada e a crescente popularização dos dispositivos sonoros portáteis individuais, entre os adolescentes, e a disponibilidade de marcas e modelos, além da alta tecnologia possibilitou o acesso a essa tecnologia. Entretanto, se esta tecnologia for utilizada de forma inapropriada, isto é, uso abusivo da duração, intensidade e/ou frequência da exposição, esta poderá acarretar em impacto adverso na função auditiva (KEPPLER et al, 2010;KNOBEL, LIMA, 2011;SANT´ANA, 2012;BARCELOS, DAZZI, 2014;SILVESTRE et al, 2016;MONDELLI et al, 2016). Além de sintomas auditivos os usuários podem apresentar sintomas extra auditivos, tais como dificuldade de concentração e atenção, memória, nervosismo e fadiga excessiva.…”
