Frequently Asked Questions (FAQs)
1. What is a high frequency transducer?
High frequency transducers are single element contact or immersion transducers designed to produce frequencies of 20 MHz and greater. Contact transducers are available in frequencies up to 225 MHz. Performance is dependent on pulser/receiver and application.
2. What is the difference between a high and low frequency transducers?
A low-frequency unit will work well in the depths of Lake Michigan or the ocean. A higher-frequency transducer will put out quicker, shorter, and more frequent sound waves. Like the ripples made when a small pebble is thrown into still water, small waves of sound move evenly out and away from the source.
3. What is a low frequency transducer?
BII's low frequency transducers are designed for uses in ocean/river/lake noise simulation, underwater communication, bioacoustics (marine mammals and fish sounds/behavior), education and generation of sound fields.
