Hearing loss at high frequencies and history of occupational noise exposureMeneses-Barriviera, Caroline LuizMelo, Juliana JandreLozza de Moraes Marchori, LucianaINTER-NOISE and NOISE-CON Congress and Conference Proceedings
Subjects in the polluted area (n = 109), who had higher iron and arsenic levels in hair and toenails than those in subjects in the control area (n = 36), had an increased risk of hearing loss at 8 kHz and 12 kHz after adjustments for age, gender, smoking and BMI. ...
Individuals from families below the federal poverty threshold (prevalence, 23.6%; 95% CI, 18.5%-28.7%) had significantly higher odds of hearing loss (multivariate adjusted OR, 1.60; 95% CI, 1.10-2.32) than those above the threshold (prevalence, 18.4%; 95% CI, 13.6%-23.2%). Conclusion ...
The propositus had bilateral severe hearing loss at the time of diagnosis, but her father showed milder presenta- tion with profound hearing loss at higher frequencies (Figure 1b). Residual hearing at lower frequencies was observed in both of the patients. No dermatologic anomalies or other ...
Middle-ear surgeries are typically associated with a high rate of hearing improvement and a low rate of sensorineural hearing loss in the conventional 250 Hz- 8 kHz range. Less well documented, however, are the relative rates of transient and permanent hearing loss at higher frequencies, which ...
Fifty-four percent had normal thresholds through the speech frequencies with moderate to profound losses at higher frequencies, or mild losses (26-40 dB) in the speech frequencies. Such persons would be at risk in daily listening situations. Twenty-two percent had moderate or greater losses (...
I was seen for it and then tested where hearing loss was found at high frequencies in both ears. I'm 52 and have no history of exposure to extreme noise nor is there hearing loss in my family. I ask because I wonder how this data is being collected accurately if new tinnitus sufferer...
Subjects with higher initial thresholds at low and mid frequencies tended to have faster changing rate at 0.25 to 2 kHz, and those with higher initial thresholds at mid and higher frequencies tended to have slower changing rate at 6 to 8 kHz in the following years. 9 From the current ...
which demonstrate elevated response thresholds and prolonged latency in IC neurons at high frequencies (unpublished findings). The failure to improve hearing thresholds in the absence of BDNF goes hand in hand with the prevention of the loss of sound sensitivity after acoustic trauma (Zuccotti et al...
The hearing loss appeared severe at higher frequencies. Figure 2 Hearing loss in Panx1 cKO mice. a: ABR waveforms recorded from Panx1 cKO and wild-type (WT) mice. b: ABR thresholds were measured at age P40-60. **P < 0.001, one-way ANOVA with a Bonferroni correction. Full size ...
