Reverberant Sound Field Equalisation for an Enhanced Stereo Playback Experience
Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2022 The topic of room equalisation has been at the forefront of research and product development for many years, with the aim of increasing the playback quality of loudspeakers in reverberant rooms. Traditional room equalisation systems comprise of a number of filters that when applied to the primary loudspeakers, additional room colouration is compensated

Repellence Effect of the New Sound for Underwater Speaker of Hydrofoil [PDF]
TransNav, 2015 In order to prevent hydrofoil colliding with cetaceans, the underwater speaker (UWS) has been installed to repel cetaceans. Yamada et al. (2012) analyzed and devised the UWS sound as it fits the cetaceans' acoustic properties to prevent the collision ...

Two novel vocalizations are used by veeries (Catharus fuscescens) during agonistic interactions.
PLoS ONE, 2015 Avian vocalizations are common examples of the complex signals used by animals to negotiate during agonistic interactions. In this study, we used two playback experiments to identify agonistic signals in a songbird species with several acoustically ...

Structural-functional characteristics of two song types in Phylloscopus humei (Phylloscopidae)
Nature Conservation Research: Заповедная наука, 2023 Several songbird species use two singing modes, which are functionally different. The first mode is preferentially used at the beginning of the breeding cycle, and serves to attract females, while the second mode is used later in the season as well as ...

Social Disruption Impairs Predatory Threat Assessment in African Elephants
Animals, 2022 The transmission of reliable information between individuals is crucial for group-living animals. This is particularly the case for cognitively advanced mammals with overlapping generations that acquire detailed social and ecological knowledge over long ...

Directional speakers as a tool for animal vocal communication studies
Royal Society Open Science, 2023 Audio playbacks are a common experimental tool in vocal communication research. However, low directionality of sound makes it hard to control the audience exposed to the stimuli.

Evaluation of the visual signal in playback by territorial responses of nuthatches
Avian ResearchA playback experiment is a well-established method for behavior research, especially in the study of the territorial responses of songbirds. Birds obtain information from multimodal signals, whereas only acoustic signals are provided in traditional ...

Mutual mother‐pup acoustic identification in Asian particolored bats
Ecology and Evolution, 2022 In many vertebrates, vocal communication is crucial in parent–offspring interactions, and parents are often able to discriminate between the calls of their own and others' offspring.
