Equipment

Our custom made equipment

Our research is only possible by using several custom made equipment.

High fidelity speaker - FISHTALK

We developend a system for high fidelity underwater sound generation. The sound is generated by a rigid plate that is actuated using purely electromagnetic forces.

Low cost hydrophone

We only can perform individual monitoring of Lusitanian toadfish nesting males due to the custom made hydrophones that we produce.

Low cost autonomous logger 0.1

Passive acoustic monitoring can be used to study geographic and temporal patterns of biological and man-made sounds.
This equipment allows us to monitor several locations in Tagus estuary.

Low cost autonomous logger 0.2

Passive acoustic monitoring can be used to study soundscape ecology.
This equipment allows us to monitor several locations at low-cost.

Setup AEP (registo audição em peixes).jp

AEP setup

To study fish audition we use this setup to perform the auditory evoked potentials (AEP) technique. In this setup we use a high fidelity speaker.
