Background: The biologic plausibility for noise stress-related cardiovascular responses is well established. Epidemiologic studies on the relationship between transportation noise and ischemic heart disease suggest a higher risk of myocardial infarction in subjects exposed to high levels of traffic noise.

Methods: To determine the risk of road traffic noise for the incidence of myocardial infarction (MI), we carried out a hospital-based case-control study in the city of Berlin.

The pathogenesis of allergies can be stimulated by adjuvant effects--i.e. air pollutants such as NOx and particles from diesel engines as well as noise--the latter especially during night-time.

This study aimed to explore the effects of increased Mg2+ intake on the activity of the outer hair cells as manifested in Click and Distortion Evoked Otoacoustic Emissions (CEOAEs; DPOAEs) in 25 animals. Thirteen animals were fed with high Mg2+ intake (39 mmol Mg2+/l in drinking water) and 12 without the Mg2+ additive. The OAE amplitudes and frequency ranges as well as the DPOAE thresholds were affected significantly less by noise exposure in the animals fed Mg2+-enriched water.

Noise has the potential to cause stress reactions. Chronic noise-induced stress accelerates the ageing of the myocardium and thus increase the risk of myocardial infarction. The involved pathomechanisms include acute increase of catecholamines or cortisol under acute noise exposure and an interaction between endocrine reactions and intracellular Ca/Mg shifts.

56 children age 7 - 10 had a medical check-up and they and their mothers completed questionnaires. Additionally the children's excretion of free cortisol was measured by HPLC in two urine samples collected at 1 p.m.

We have recently demonstrated in the guinea pig that preventive dietary magnesium supplement can significantly reduce impulse noise induced hearing loss by on average 18 dB. The purpose of the present study was to examine whether magnesium might also have a therapeutic effect on noise trauma. Anesthetized guinea pigs were exposed to an impulse noise series (1/s) of L(peak) 167 dB (L(eq,ls) 127 dB) for 38 min.
