Minke Whale (Balaenoptera Acutcrostrata) Response to a Sound Playback Experiment
2003Abstract : A song playback experiment to singing minke whales on the Great Barrier Reef was carried out. Songs were played to singers at ranges of 0.5-2.0km A remotely monitored sonobuoy array was used to monitor whale movements and singing behavior.

Sound Playback Experiments with Southern Right Whales ( Eubalaena australis )
Science, 1980A variety of sound recordings were played to southern right whales. Whales approached the loudspeaker and made frequent sounds in response to recordings of other southern right whales, but swam away and made relatively few sounds in response to playbacks of water noise, 200-hertz tones, and humpback whale sounds.

Signals and assessment in African elephants: evidence from playback experiments
Animal Behaviour, 1999A series of playback experiments using two elephant vocalizations, the 'musth rumble' and the 'oestrous call', was carried out in Amboseli National Park to examine signalling and assessment in African elephants, Loxodonta africana. In response to the musth rumble of a high-ranking male other musth males approached the speaker aggressively, whereas ...

Conducting Playback Experiments and Interpreting their Results
1992The aim of this chapter is to discuss factors to be considered in the design, execution and interpretation of playback experiments. Most of these factors will be of general concern, even though my examples will be drawn heavily from two-speaker designs with frogs and toads as subjects.

Recognition of familiarity on the basis of howls: a playback experiment in a captive group of wolves
Behaviour, 2015Playback experiments were conducted with a pack of captive Iberian wolves. We used a habituation–discrimination paradigm to test wolves’ ability to discriminate howls based on: (1) artificial manipulation of acoustic parameters of howls and (2) the identity of howling individuals.

An intentional vocalization draws others’ attention: A playback experiment with wild chimpanzees
Animal Cognition, 2014A vital step in the evolution of language is likely to have been when signalers explicitly intended to direct recipients' attention to external objects with the use of referential signals. Although animal signals can direct the attention of others to external events, such as in monkey predator alarm calls, there is little evidence that this is the ...

Guinea pig responses to conspecific vocalizations: Playback experiments
Behavioral and Neural Biology, 1981Eight playback experiments are described in which guinea pigs (Cavia porcellus) were individually observed while a tape recording of various guinea pig vocalizations was played. The behavior of subjects was also observed in a silent control test, and in response to nonvocal sounds of varying frequencies.

Experiments with electron scanning for magnetic recording and playback of video
IEEE Transactions on Audio, 1963Present day video tape uses high speed mechanical scanning, with rapid wear of tape and heads. Electron beam scanning is proposed to eliminate mechanical problems and to allow the use of low cost tape. Development work has been conducted on a recording tube using a high density sheet beam to energize a simplified 500 element magnetic head. For playback

A First Assessment of Birdnet Performance at Varying Distances: A Playback Experiment
Ardeola, 2023Bird vocalisations, like any other acoustic signals, attenuate over distance, and therefore their structure degrades progressively. Such degradation may have an impact on the ability of automated signal recognition software, to detect and correctly identify bird vocalisations.

Behavioural effects of persistent human disturbance: a playback experiment in a forest bird
Ecology LettersIncreasing human presence and activities expose wild animals to persistent disturbances. Disturbed populations often become tolerant towards humans, although the underlying mechanisms are poorly understood. We used playback experiments to manipulate perceived level of human disturbance in great tits (Parus major).
