Hemispherical Hydrophone
BII7040 Series Hemispherical Hydrophone
The BII7040 series hydrophones provide 60° directivity response approximately at fs resonance, which is designed to detect known sound sources with wide beam angle, and provide omnidirectional directivity response in low frequency range in which the wavelength is much greater than the physical size of the hydrophone. With Hemispherical Hydrophones, noises at certain directions are reduced, and maximum response to signals is at acoustic axial direction. Hemispherical hydrophones are optimum wide beam acoustic receiving apertures for being installed on underwater platforms.
