Custom 20Hz~80kHz Spherical Hydrophone for Acoustic Testing
Product Description
Custom 20Hz~80kHz Spherical Hydrophone for Acoustic Testing
The spherical hydrophone features outstanding omnidirectionality as its core characteristic, achieving highly consistent acoustic response across all spatial angles. This property enables it to accurately reproduce sound pressure information in complex sound fields and deliver research-grade measurement accuracy. It serves as an ideal reference device for sound field spatial distribution measurement, noise source tracing and acoustic material testing.
