Acute or chronic acoustic trauma
may cause high-frequency sensorineural hearing loss.
A 27-year-old volunteer fireman presented 3 weeks after he had experienced an acoustic trauma
as the result of a blast from the siren of a fire engine.
Subsequently, an acoustic trauma
at 2 kHz was inflicted and all postmeasurements were done within 7 to 8 days after trauma.
Etiology of tinnitus in the 117 ears Etiology n (%) Presbycusis 38 (32.5) Unknown (in patients with 37 (31.6) sensorineural hearing loss) Acoustic trauma
18 (15.4) Unknown (in patients with 15 (12.8) normal hearing) Meniere's disease 4 (3.4) Head injury 2 (1.7) Acoustic neuroma 2 (1.7) Chronic otitis media 1 (0.9) Table 2.
(202) Others have shown that chronic infusion of both neurotrophin-3 and GDNF into the inner ear provided significant protection from acoustic trauma
in guinea pigs.
[Treatment of acute inner ear deafness (sudden deafness and acoustic trauma
Theoretical reasons for preserving the stapedius tendon include the possibility of reducing the chance of barotrauma and acoustic trauma
and improving the hearing in noisy environments.
Audiometry of the left ear showed a high-frequency sensorineural hearing loss that was consistent with acoustic trauma
SSHNL may be caused by surgery, acoustic trauma
, or sudden deafness, a phenomenon in which hearing loss occurs without obvious cause.
A police officer outside of the bus suffers an acoustic trauma
. At 8:30 p.m, 15 minutes before the match is to be kicked off, UEFA, football's European governing body, postpones it until the following day.
Acute acoustic trauma
(AAT) is a sudden sensorineural hearing loss induced by acoustic overstimulation, most frequently due to exposure to intense impulse noise.
In the present study, immunohistochemical staining and Western blotting assay were applied to quantitate the change of PV inhibitory neurons following chronic acoustic trauma
. The findings hopefully advance our understanding of the neural mechanism underlying acoustic trauma-induced hearing loss at the cortical level.
Although inflammatory cell infiltration of the cochlea after acoustic trauma
is well known, the role of proinflammatory cytokines released by these cells in noise-induced hearing loss is still not fully clear.
This abrupt event is called acoustic trauma
. Such was the case with my dad.
Patients with a history of premature birth, low birth weight, hyperbilirubinemia, systemic conditions, ototoxic medications, or acoustic trauma
