Abstract
While noise is now considered a marine hazard that can directly affect
cetaceans and induce a stranding, no clinical approach has yet introduced the detection
of a possible hearing loss at a stranding site as a necessary practice. Here
we present the second generation of an autonomous and portable auditory screening
system for cetacean clinical and research purposes. This system is composed
by two independent and autonomous modules that build a more versatile, lighter
and interference isolated system. The improvement relies on the isolation between
modules and their independency on many situations. The system is separated in
two modules. The first one contains the low voltage biopotential amplification system
and the acustic signal transmiter . The second module will activate only when
needed for some frequencies and levels driving high voltage to the transducers thus
avoiding interferences with the first module containing the low voltage amplifications
system. The tool has been successfully tested for research purposes in captive
dolphins and calibrated for a stranding site diagnoses operation.
