Digital Sensors and Sensor Sysstems


Abstract: We present an analyse of the environmental noise in absence of seismic activity detected by a seismic station (located in Gualdo in the province of Macerata equipped with two type of accelerometer sensors) and compare the average H/V noise curves with the results obtained using a velocimeter. The noise can be divided into various types: sensor noise, natural environmental noise, anthropic noise, microseismic noise. In this study we want to analyse the noise in frequency domain acquired by different sensors to understand if it is possible to extrapolate useful information from the seismic noise recording acquired by accelerometer rather than by velocimeter, in order to determine the sensorís limits.


Keywords: Seismic noise, Microtremor, Accelerometer, Ambient vibrations, H/V, HVSR.
