Review
Noise-induced hearing loss (NIHL) still remains a problem in developed countries, despite reduced occupational noise exposure, strict standards for hearing protection and extensive public health awareness campaigns. Therefore NIHL continues to be the focus of noise research activities. This paper summarizes progress achieved recently in our knowledge of NIHL. It includes papers published between the years 2008-2011 (in English), which were identified by a literature search of accessible medical and other relevant databases. A substantial part of this research has been concerned with the risk of NIHL in the entertainment sector, particularly in professional, orchestral musicians. There are also constant concerns regarding noise exposure and hearing risk in "hard to control" occupations, such as farming and construction work. Although occupational noise has decreased since the early 1980s, the number of young people subject to social noise exposure has tripled. If the exposure limits from the Noise at Work Regulations are applied, discotheque music, rock concerts, as well as music from personal music players are associated with the risk of hearing loss in teenagers and young adults. Several recent research studies have increased the understanding of the pathomechanisms of acoustic trauma, the genetics of NIHL, as well as possible dietary and pharmacologic otoprotection in acoustic trauma. The results of these studies are very promising and offer grounds to expect that targeted therapies might help prevent the loss of sensory hair cells and protect the hearing of noise-exposed individuals. These studies emphasize the need to launch an improved noise exposure policy for hearing protection along with developing more efficient norms of NIHL risk assessment.

OBJECTIVES/HYPOTHESIS
To test whether noise-exposure, which activates a cochlear immune response with cytokine expression and infiltration of circulating leukocytes could augment the response to antigen (Ag).
STUDY DESIGN
Randomized, prospective, mice.
METHODS
We sensitized mice to an Ag, injected it intrathecally, and subsequently exposed the mice to noise (8-16 kHz, 90, 100, or 118 dB for 2 hours). Control mice received either noise exposure alone (100 or 118 dB), Ag challenge alone, intrathecal surgery and phosphate-buffered saline injection or no treatment. Four hours or 7 days later the mice were killed and cochlear sections were evaluated immunohistochemically for CD45, ICAM-1, and phospho-nuclear transcription factor-kappaB expression.
RESULTS
Intrathecal Ag injection caused no hearing loss, but did result in a small immune response. Loud noise (118 dB) caused severe hearing loss and slight inflammation. The number of CD45-positive cells was significantly greater in the Ag plus-118 dB noise group relative to the Ag-alone group or 118 dB noise-exposure group. ICAM expression was seen in the lower part of the spiral ligament and small vessels within the normal cochlea. The amount of expression increased after Ag injection and acoustic trauma. Activated nuclear transcription factor-kappaB occurred in the nuclei of hair cells, supporting cells, spiral ligament fibrocytes, and neurons 4 hours after noise exposure.
CONCLUSIONS
It seems that noise exposure can activate a cochlear immune response, which in the presence of Ag, allows for greater recruitment of inflammatory cells than occurred in response to Ag alone.

Lesions produced by exposure to noise are frequent in everyday life. Injuries may be found in all systems of the human body, from the digestive to the endocrine, from the cardiovascular to the nervous system. Many organs may be damaged, the ear being one of them. It is known that noise produced by factories, airports, musical instruments and even toys can cause auditory loss. Noises in nature can also cause acoustic trauma. This report is the case history of acoustic trauma caused by lightning. The patient was studied with CAT scan, electroencephalogram, and brain mapping, impedance audiometry with tympanogram and acoustic reflex, audiometry and evoked otoacoustics emissions: distortion products and transients.
