Applied Acoustics AA201 Boomer Plate

Science Center Objects

The AA201 boomer plate is used with a high-resolution seismic system

Description

The boomer plate produces a repeatable pulse in the 1-6kHz frequency range using an electrodynamic transducer that can be powered by a capacitor discharge system. It has a penetration on the order of 150 m (depending on sediment type) and provides a balance between resolution and penetration.  It can be used in freshwater lakes where a sparker would not be suitable.

Complementary Systems

Seismic sounds sources need to be used with some form of “listening”/recording device.  Examples include a Geometrics GeoEel multi-channel hydrophone streamer, or an Applied Acoustics hydrophone streamer
