Bioacoustics
Loggerhead Instruments manufactures hardware and software for bioacoustics research. Our aim is to provide complete solutions that enable the researcher to collect and analyze large amounts of acoustic data.
DSG Recorder
The DSG Recorder is a new long-term, low-power recorder of acoustic signals capable of sampling at 80 kHz continuously and up to 400 kHz in burst mode. The DSG records based on a schedule file system that allows arbitrary record times and durations. DSG stands for 'digital spectrogram' because one of its record modes allows creation of spectrograms from stuttered recordings. This is useful for 'lossy' data compression of high frequency signals, such as those produced by dolphins and bats, in which the main goal is to detect the presence of the animal.
The DSG is offered in four systems:
DSG-Ocean
The DSG-Ocean is used for underwater acoustic recording. The system comes complete with a DSG recorder, hydrophone, underwater housing, and SDHC memory card. Housings are available in either 100-m rated PVC or 2000-m rated anodized aluminum.
DSG-Remora
The DSG-Remora is the animal-borne tag version of the DSG. The Remora has the same acoustic recording capabilities as the DSG, and also includes 3D accelerometers, compass, depth, and temperature sensors. The Remora is housed in a flexible PVC hose which can be customized in length for individual applications.
DSG-Air
The DSG-Air comes complete with a DSG recorder, waterproof microphone, case, and SDHC memory card.
DSG
The base DSG board available for integration into other housing and hardware designs.
DSG Guarantee
We know how important it is to have working instruments when it is time to deploy in the field. Thus, each DSG comes with a one year warranty and a replacement policy should you have problems when you are trying to deploy.
