 Marschall Acoustics patents in 
			the United States of America (USA) and other countries cover almost every way of making a thinline
			towed hydrophone array or seismic streamer with low self-noise levels.  The technology is also used in
			stationary horizontal and vertical hydrophone arrays for geophysical exploration and production,
			oceanographic research, and undersea warfare such as ASW and harbor security.


 Marschall Acoustics innovative hydrophone
			designs include the use of piezoplastics such as PVDF, piezoceramics, and fibre optics.  Some of our towed hydrophone
			array and thinline solid streamer designs can operate at high speeds and full ocean depth. 
			      Our experience in moving coil electrodynamic underwater transducer design has lead directly to our
			development of phase-coherent or time-aligned loudspeaker systems for professional sound reinforcement.
