The aim of this study was phonometric analysis at different altitudes of the acoustic output of a widely used earphone model, along with its consequences on audiological investigations conducted under such environmental conditions. The transfer function of a TDH-39P earphone was analyzed with an artificial ear under nine different altitude levels, from sea level up to 35,000 ft, inside a hypobaric chamber.

Materials And Methods: Two fresh pig jaws were obtained from a local slaughterhouse, and nine bone samples with a standard size (1 cm) were harvested from each jaw: three using piezosurgery, three with a multiblade bur mounted on a surgical handpiece, and three with a diamond bur mounted on a high-speed handpiece, for a total of 18 samples. Two samples for each harvesting method were examined by scanning electron microscope (SEM), observing four surfaces per sample.

This study was aimed to evaluate if workers exposed to environmental stressors, including the urban traffic noise, might show significant differences compared to a control group in neuro-psychological and emotional profile as well as neurophysiological functions. In particular if these differences could be evidenced by the application of the "oddball paradigm" for event related potential P300 component. The study consisted of the following examinations: (1) exposed workers vs.
