Abstract
This report discusses the acoustic calibration of the Dual Accelerometer Vector Sensor (DAVS) carried out at the Arsenal do Alfeite acoustic tank, in Lisbon, on 17th and 18th of November 2016. This is a revision of previous report SiPLAB 4/17 of April 2017 [1], with a more comprehensive description of the tank limitations as well as the signal path and processing steps for obtaining calibrated curves for sensitivity and directivity in the band 0.5 to 4 kHz. Additional results from previously unprocessed data, not included in the previous report, are given for accelerometers data captured when device Z axis is pointing to the source.
