Commissioned by the Netherlands Ministry of Infrastructure and the Environment RIVM organized an expert meeting about reaction to sudden noise, and the way peak noise is dealt with in science, policy and practice. The aim was to exchange knowledge and ideas and formulate recommendations about situations with sudden high noise levels. Examples were presented from theory and practice, pertaining ...

INTRODUCTION: It is a well known fact that noise annoyance depends on the traffic mode. Much less is known about differences in physiological effects, especially on combined effects. Therefore, we investigated the effects of air (AI), road (RO) and rail (RA) traffic noise on sleep in the AIRORA study. METHODS: 72 subjects (40 ± 13 years, 32 male) were polysomnographically investigated during 11...

An air-coil sensor (ACS) is a type of induction magnetometer used as a transducer to measure the variations of a magnetic field. This device is widely applied in helicopter transient electromagnetic method (TEM) exploration. Most helicopter TEM explorations generate common-mode noise and require extreme ACS specifications, both of which inevitably challenge geophysical explorations. This study ...

Noise induced hearing loss (NIHL) is one of the most important occupational disease worldwide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

Absorption: The mechanism by which acoustic energy is converted into heat by friction in absorptive media. See Pack. Airborne: A noise that is transmitted by the atmosphere and can be heard outside the car. Air Cleaner Housing: The housing that retains the air filter and forces the route of combustion air through the filter medium. Air Filter: The medium that eliminates the major particulate fr...

in recent years noise has been well known as an environmental pollution. particularly its effects will be more serious in some environments including hospitals which patients need a calm and peaceful condition. this study aims to evaluate hospitals noise pollution level. this study is a cross-sectional study. noise measurements were made in all hospital wards in a workday and weekend from 8 to ...

After completing our study of lead and aggressive crime [10], it came to our attention that we might have erroneously combined lead in air data from two neighbouring air quality monitoring stations for the Boolaroo, New South Wales (NSW) suburb. We re-examined the data we initially compiled in 2011/2012, and it does appear that data from two neighbouring sites with overlapping names have been c...
