Exposure amplitude and repetition affect bottlenose dolphin behavioral responses tosimulated mid-frequency sonar signals
Exposure amplitude and repetition affect bottlenose dolphin behavioral responses to simulated mid-frequency sonar signals" (2013). a b s t r a c t a r t i c l e i n f o Keywords: Acoustic exposure Behavioral response Bottlenose dolphin Dose–response Sound Thirty bottlenose dolphins (Tursiops truncatus) participated in a controlled exposure study using an acoustic stimulus that consisted of a si...
متن کاملDelphinid behavioral responses to incidental mid-frequency active sonar.
Opportunistic observations of behavioral responses by delphinids to incidental mid-frequency active (MFA) sonar were recorded in the Southern California Bight from 2004 through 2008 using visual focal follows, static hydrophones, and autonomous recorders. Sound pressure levels were calculated between 2 and 8 kHz. Surface behavioral responses were observed in 26 groups from at least three specie...
متن کاملBlue whales respond to simulated mid-frequency military sonar
Mid-frequency military (1-10 kHz) sonars have been associated with lethal mass strandings of deep-diving toothed whales, but the effects on endangered baleen whale species are virtually unknown. Here, we used controlled exposure experiments with simulated military sonar and other mid-frequency sounds to measure behavioural responses of tagged blue whales (Balaenoptera musculus) in feeding areas...
متن کاملCognitive Adaptation of Sonar Gain Control in the Bottlenose Dolphin
Echolocating animals adjust the transmit intensity and receive sensitivity of their sonar in order to regulate the sensation level of their echoes; this process is often termed automatic gain control. Gain control is considered not to be under the animal's cognitive control, but previous investigations studied animals ensonifying targets or hydrophone arrays at predictable distances. To test wh...
متن کاملDiscrimination of Cylinders with Different Wall Thicknesses Using Neural Networks and Simulated Dolphin Sonar Signals
This paper describes a method integrating neural networks into a system for recognizing underwater objects. The system is based on a combination of simulated dolphin sonar signals, simulated auditory filters and artificial neural networks. The system is tested on a cylinder wall thickness difference experiment and demonstrates high accuracy for small wall thickness differences. Results from the...
