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.


Licensees


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.
