uSound — a line for underwater sound recording

Purpose

uSound is a configurable set of devices for professional sound recording, designed for marine biologists, geologists, oceanographers, as well as underwater sound hobbyists and enthusiasts.

What the set includes

The uSoundBox switching unit provides power for active hydrophones, manual gain control, pluggable AGC, and two line outputs for connecting headphones and a recorder. At the first stage, two types of differential low-noise hydrophones are used for different frequency ranges — disk piezo elements for recording low-frequency signals and cylindrical piezo elements for recording high-frequency signals. The set of hydrophones is planned to be expanded in the future.

What this means in practice

The set is configured for the task: the hydrophone is chosen according to the frequency range of the sound of interest, while uSoundBox powers the active hydrophones, lets you set the gain manually or switch on the AGC, and sends the signal to two outputs at once — to headphones, so you can monitor the recording, and to a recorder, so you can make it.

Development status

The range is under development, so the technical specifications of the hydrophones and the switching unit have not yet been published. To find out the state of the work and the terms, leave a request using the form on this page.
