Passenger cars differ in their levels of emitted noise and mileage, which can have a negative impact on the environment humans. This was confirmed by results this study generated passenger that same parameters, or are one type. The loudest place tested vehicles turned out to be combustion engine compartment, with average level exceeding 90 dB exhibiting noticeable, significant increase alongsid...

Noise is one of the main parameters to be considered to achieve a healthy indoor ambience in ferries. Therefore, the noise standards need to be more specialized and specifically based on real sampled data and case studies. In the present research, the noise levels in a ship, under different working conditions, were sampled and compared with those specified in the new and old standards. An initi...

Background: The noise caused by traffic is an increasingly prominent feature of urban environments. However, limited studies have been focused on the assessment of exposure-response relationship between road traffic noise exposure and driving behaviors in Iran. The present study aimed to investigate the prevalence of the violations caused by road traffic noise exposure in Qazvin, Iran. Methods...

the intensity of noise, heat and light were measured in 10 different groups of food processing plants with 3820 employees. noise was measured in 265 working places and if the over-all noise was more than t.l.v. (90dba), the octave band analysis was carried out. effective temperature (e.t) or corrected effective temperature (c.e.t) were measured in 183 working places and air velocity relative hu...

Abstract Schools in urban areas are often located with high traffic and noise pollution that affect the overall sonic quality of external spaces. Due to this, teachers students exposed levels, this condition could have an impact on perceptive-cognitive neurobehavioral aspects, determining auditory extra-auditory effects from exposure noise. The BRiC - ID14 project, funded by INAIL, investigates...
