The features and mechanism of Acute Acoustic Trauma (AAT) together with available treatments are discussed and the current guidelines in use by the Bundeswehr are also presented.

background and aims. trauma is one of the major factors associated with temporomandibular joint disorders (tmd). these disorders result from macro-trauma or micro-trauma. macro-trauma might be iatrogenic; for example, from intubation procedures, third molar extraction procedures, and lengthy dental appointments. the aim of this study was to evaluate the effect of lengthy root canal therapy (mor...

Acoustic overstimulation is one of the major causes of hearing loss. Glutamate is the most likely candidate neurotransmitter for afferent synapses in the peripheral auditory system, so it was proposed that glutamate excitotoxicity may be involved in noise trauma. However, there has been no direct evidence that noise trauma is caused by excessive release of glutamate from the inner hair cells (I...

Over the last decade, the consequences of acoustic trauma on the functional properties of auditory cortex neurons have received growing attention. Changes in spontaneous and evoked activity, shifts of characteristic frequency (CF), and map reorganizations have extensively been described in anesthetized animals (e.g., Noreña and Eggermont, 2003, 2005). Here, we examined how the functional proper...
