Hydrophone Rentals
Dynamic Ocean carries multiple leading hydrophone brands to suit a variety of applications. Our experienced team of acoustic specialists can create customized solutions tailored specifically to meet your unique in-field requirements.
In addition to offering equipment rental services, we can also provide comprehensive technical support to train your staff on both the operation and detailed processing of hydrophone data. Alternatively, if preferred, we can supply a qualified acoustics technician to assist directly with your compliance program and ensure all regulatory requirements are met efficiently.

Portable Deployment
Our hydrophones are carefully set up, fully charged, and primed for immediate deployment. Each hydrophone system is housed in a robust hard case, ensuring that all equipment remains securely protected and durable enough to withstand the most challenging and demanding field operations.
Customized Deployment Solutions
We offer advanced acoustic release systems designed for customized, long-term deployments of a wide range of instrumentation at various depths, ensuring secure and reliable underwater operations.
Hydrophone Calibration
We can support the rental of equipment you require for ‘field calibration’ of your hydrophone for times this is required by Fisheries and Oceans Canada (DFO). We offer a rental of a pistonphone and sound level meter. The pistonphone is coupled to the hydrophone and plays a tone of known frequency (250 Hz) and known amplitude (e.g., 114 dB), and this is then recorded and measured on the hydrophone to confirm the levels recorded by the hydrophone.
A calibrated sound level meter is also included in our calibration package to confirm the output of the pistonphone in the field and also to measure the sound pressure level within the coupler.
Pistonphone - GRAS 42AA Pistonphone, Class 1
Sound Meter - Bruel & Kjaer 2245 Sound Level Meter
