Audiogram of a harbor porpoise (Phocoena phocoena) measured with narrow-band frequency-modulated signals.
The underwater hearing sensitivity of a two-year-old harbor porpoise was measured in a pool using standard psycho-acoustic techniques. The go/no-go response paradigm and up-down staircaseExpand

Transmission beam pattern and echolocation signals of a harbor porpoise (Phocoena phocoena).
The transmission beam pattern of an echolocating harbor porpoise (Phocoena phocoena) was measured in both the vertical and horizontal planes. An array of seven Brüel and Kjaer 8103 hydrophonesExpand

The acoustics of the snapping shrimp Synalpheus parneomeris in Kaneohe Bay
Snapping shrimp are among the major sources of biological noise in shallow bays, harbors, and inlets, in temperate and tropical waters. Snapping shrimp sounds can severely limit the use of underwaterExpand

The broadband social acoustic signaling behavior of spinner and spotted dolphins.
Efforts to study the social acoustic signaling behavior of delphinids have traditionally been restricted to audio-range (<20 kHz) analyses. To explore the occurrence of communication signals atExpand

Measurement of echolocation signals of the Atlantic bottlenose dolphin, Tursiops truncatus Montagu, in open waters.
The echlocation signals of two Atlantic bottlenose dolphins, Tursiops truncatus, were measured while the animals were involved in a target‐detection experiment conducted in open waters. The timeExpand

An ecological acoustic recorder (EAR) for long-term monitoring of biological and anthropogenic sounds on coral reefs and other marine habitats.
Keeping track of long-term biological trends in many marine habitats is a challenging task that is exacerbated when the habitats in question are in remote locations. Monitoring the ambient soundExpand

Acoustic properties of humpback whale songs.
A vertical array of five hydrophones was used to measure the acoustic field in the vertical plane of singing humpback whales. Once a singer was located, two swimmers with snorkel gear were deployedExpand

Automatic gain control in the echolocation system of dolphins
In bats and technological sonars, the gain of the receiver is progressively increased with time after the transmission of a signal to compensate for acoustic propagation loss. The currentExpand

Detection of complex echoes in noise by an echolocating dolphin.
Dolphins echolocate with short broadband acoustic signals that have good time resolution properties. Received echoes are often complex, with many resolvable highlights or components caused byExpand
