Moderate variations of mood/emotional states related to alterations in cochlear otoacoustic emissions and tinnitus onset in young normal hearing subjects exposed to gun impulse noise

Comparison of otoacoustic emissions in patients with tinnitus having normal hearing versus mild hearing loss

“…Based on previous reports and in accordance with the results found in the present study, we can say that whatever the etiology, at the same levels of hearing thresholds, DPOAE seems to be lower when chronic tinnitus is present [22][23][24][25][26] . Liu et al 24 analyzed the association between OAE and tinnitus in 306 ears with tinnitus (with or without hearing loss) and observed that in 94.8% of those with hearing loss and tinnitus the DPOAE-gram shows lower amplitude or was absent within the frequency range of elevated pure-tone-threshold.…”

The Risks of Amplified Music for Disc-Jockeys Working in Nightclubs

“…These findings agree with those in the study by Nicolas-Puel et al (2006), showing that exposure to acute sound trauma is associated with nonlateralized tinnitus, consistent with a symmetrical hearing loss. On the contrary, young military personnel who have been exposed to gunfire describe tinnitus that is lateralized to the side of their hearing loss (Job et al 2004;Khalfa et al 1997).…”

Susceptibility to Tinnitus Revealed at 2 kHz Range by Bilateral Lower DPOAEs in Normal Hearing Subjects with Noise Exposure

“…Despite the fact that the design of the study could not allow us to go further with this hypothesis, some recent studies pointed out a correlation between the 2-kHz range, stress, and tinnitus. After target practice rounds, DPOAEs at 2 kHz have been shown to be decreased only in the most anxious subjects [Job et al, 2004] among young soldiers experiencing transient tinnitus. Furthermore, AAT is an acute stress and otoacoustic emissions in the 2-kHz range have been shown to be good predictors of tinnitus persistence after an AAT [Nottet et al, 2006].…”
