Review
Cochlear damage is often thought to result in hearing thresholds shift, whether permanent or temporary. The report of tinnitus in the absence of any clear deficit in cochlear function was believed to indicate that hearing loss and tinnitus, while comorbid, could arise independently from each other. In all likelihood, tinnitus that is not of central nervous system origin is associated with hearing loss. As a correlate, although a treatment of most forms of tinnitus will likely emerge in the years to come, curing tinnitus will first require curing hearing loss.

Review
Acoustic trauma (AT) is permanent hearing loss after a single noise exposure. A few human cases resulting from continuous, i.e., nonimpulsive noise, have been reported as reviewed by Ward [(1991). "Hearing loss from noise and music," presented at Audio Engineering Society, New York, October 4-8]. This paper updates that review by examining 11 cases in nine reports, from 1950 to 2006, with the intention of determining minimum exposures that may cause AT, including the potential risk of exposure to noise from magnetic resonance imaging machines. Diffuse-field related levels above 120 dBA for 10 s or more, or above 130 dBA for 2-3 s (values well above OSHA's unprotected exposure limits), can lead to AT. These cases appear to represent a susceptible fraction of the population, because much more intense exposures (e.g., 130 dBA for 32 min) have been tolerated by groups of volunteers who suffered only temporary threshold shifts. AT from continuous noise is unlikely to occur in OSHA-compliant hearing conservation programs, and probably rare enough in the general civilian population that clinical trials of drugs aimed at treating it are unlikely to be practical. AT from impulse noise, such as gunfire, which is specifically not the topic of the current work, is more amenable to clinical trials, especially in military settings.

Review
Eight male patients suffering from Menière's syndrome are presented. All patients sustained sudden or prolonged exposure to severe noise levels and suffer from acoustic trauma. The incidence of Menière's syndrome in our group of patients is significantly higher than in series reported in the normal population. Our presentation supports the implication of acoustic trauma as a possible cause of Menière's syndrome.

Review
Acoustic trauma is one of the major causes of hearing loss and tinnitus, particularly in industrial environments. Noise-induced hearing loss (NIHL) results in direct mechanical damage as well as in indirect metabolic processes. Metabolic disorders have multiple origins: ionic, ischemic, excitotoxic and production of cochlear free radicals causing cell death, due to necrosis or apoptosis. The efficacy of magnesium, administered either to prevent or to treat NIHL has been demonstrated in several studies in animals and in humans. Magnesium, which easily crosses the hematocochlear barrier, presents neuroprotective and vasodilatory effects, and thus, is able to limit the cochlear damage. Magnesium therapy is well documented because it is usually prescribed in other pathologies. Its side effects and contraindications are few and it is cheap. This article presents also some arguments that emphasize the interest of magnesium therapy in acoustic trauma.
