Instrument Description
Hydrophone
Hydrophones are devices containing transducers that convert underwater sound waves into electrical signals. They are acoustic instruments that can process data while they are being collected to produce calibrated waveform data. Hydrophones are typically used to study vocalizations of marine mammals, ship traffic and ambient noise.
Hydrophone instruments include high frequency (10 to 200,000 Hz) and low frequency (0.1 to 1600 Hz) models. Hydrophone data at certain locations are used to detect vocalizations, which are examined to study seasonal shifts in cetacean populations. Whale songs are detectable by hydrophones from tens to hundreds of kilometres away from the source. Some species, such as orcas, have resident, transient and offshore sub-populations that are identified by their unique calls.
