We have a client company that is about to go into production of a small, towed acoustic array
that can localize marine mammals in an area.
For this reason, an acquisition and processing system for an acoustic array
based on MEMS microphones is reduced to two basic elements: MEMS microphone and a processing system usually based on an FPGA (Field Programmable Gate Array)
Simley, Development of an acoustic array
for wind turbine aeroacoustic noise analysis [M.S.
processing is today an essential part of many applications involving the analysis of audio signals, such as hearing aids, hands-free devices, or immersive audio recording.
So far, test-bench systems have already been developed in this way for Multipole Acoustic Array
Logging Tool (Lu et al., 2010; Lu et al., 2012), Array Induction Logging Tool (Men et al., 2011), Micro-resistivity Scanning Imaging Logging Tool (Yang et al., 2012), and have successfully applied to the test and calibration of tool modules and subs.
Zhuo et al., "The design and implement of acoustic array
sensor network platform for online multi-target tracking," in Proceedings of the 8th IEEE International Conference on Distributed Computing in Sensor Systems (DCOSS '12), pp.
The ray technique uses an acoustic array
with 32 to 152 microphones and a technique similar to a lens by measuring the time of flight to each of the microphones.
Within a fixed acoustic array
, this assumption may create bias in resultant space-use estimates by excluding the most mobile individuals as well as individuals who are only detected at receivers placed in a straight line.
systems; theory, implementation, and application.
Each pod type has an acoustic array
and an acoustic wake-up sensor.
Attaching DAS equipment to one end of a standard fiber optic cable, such as those used for telecommunication, creates an acoustic array
of virtual microphones every 10 meters along the fiber.
In the first case however, view formation is quite slow, and there are problems with technological acoustic array
control in the second case.
