US Patent 11889760 Seismic pressure and acceleration sensor

A seismic pressure and acceleration sensor can include a hydrophone having a volume encapsulated by an enclosure. The enclosure can include, a pressure-sensitive surface and a pressure-insensitive support structure. The sensor can also include an accelerometer positioned within the encapsulated volume. The accelerometer is mechanically isolated from the pressure-sensitive surface and mechanically coupled to the pressure-insensitive support structure.
