Abstract
A wireless ambient noise accelerometer (ANA) device for data recording, based on a tri-axial acceleration sensor, has been developed by us. The mobile device has wireless control allowing great mobile convenience. The device is designed to record microseismic ambient noise on the basis of which to analyze the fundamental response frequency at the recording site. It is based on the three component ADXL355z acceleration sensor, featuring a 24bit ADC. The applied method for the data analysis is the H/V spectral ratio technique. We performed simultaneous recordings of ambient noise at two sites with two systems – ANA and a velocimeter GBV-316. The obtained results are similar, which reveals the applicability of ANA for ambient noise recording and site effects analysis.
