Massa has pioneered the development of a wide variety of electroacoustic products for
commercial applications for more than a half century. Some of these are ultrasonic sensor systems
and transducers for non-contact distance measurement for use in air and other gaseous environments.
Others are underwater sonar type transducers and systems that are used by the oceanographic
community
for applications such as sub-bottom profiling, side scan sonars, bottom mapping systems,
well head blowout protectors, and underwater communication.
