Sound quality testing taken to a new level
Brüel & Kjær’s Head and Torso Simulator (HATS), binaural microphones and PULSE Sound Quality software were used to analyse the sound quality behaviour of different types of Orona lifts, to correlate the sound quality with the different noise sources and to study the most appropriate ways to improve lift comfort. Orona S. Coop. (manufacturer of lifts), Mondragon Goi Eskola Politeknikoa (MGEP) S. Coop. (Engineering Faculty of Mondragon University) and Ikerlan S. Coop. (Research Centre) have formed a consortium and established a stable working group of engineers to investigate the Sound Quality ... |

Studies reveal why drinking water wells are vulnerable to contamination
New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells.
All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well.
More than 100 million people in the United States receive their drinking water from public groundwater systems, which can be vulnerable to naturally occurring contaminants such as radon, uranium, arsenic, and man-made compounds, including fertilizers, ... |
