GEOSCOPE Station Noise Levels

Upper mantle anisotropy beneath the Geoscope stations

Seismic anisotropy has been widely studied this last decade, particularly by measuring splitting of vertically propagating core shear waves. The main interest in this technique is to characterize upper mantle flow beneath seismic stations. On the other hand, the major restriction in this method is that a single station gives a single anisotropy measurement. Alternative methods have been develop...

Analysis of Noise and Vibration in Subway Station Hall

This study use noise and vibration analytical system to test and analyze the noise and vibration of subway station hall, draw the conclusion: analysis the noise test results when the vehicles through the subway station hall. The noise rises as the frequency increases, gets the peak value nearby 5000 Hz, the high of test point gives lesser influence to noise contribution. The vibration occurred ...

The Development of a Sustainability Geoscope: An Interim Report

The Geoscope is an instrument for globally comparative observation and analysis of regions with respect to measurements that have an impact on sustainability. In this sense, the Geoscope is an observation instrument for the anthropocene. This is the era which humankind has just entered and where the tight interlinkages between human and natural environment have become obvious and are taken into...

Noise levels in dental schools.

OBJECTIVE To measure and analyse noise levels in the learning-teaching activities at the Dental School of the University of Porto (Portugal). MATERIALS AND METHODS Sound levels were measured in five different practice areas and laboratories, selected as representative of a variety of learning-teaching activities. The noise levels were determined using a precision sound level meter that was po...
