Gas bubbles in the ocean are produced by breaking waves, rainfall, methane seeps, exsolution, and a range of biological processes including decomposition, photosynthesis, respiration and digestion. However one biological process that produces particularly dense clouds of large bubbles, is bubble netting. This is practiced by several species of cetacean. Given their propensity to use acoustics, ...

Multitrack recordings of a mixed adult choir with 23 singers were collected in order to investigate the influence of varied room acoustical conditions on a choir’s performance with regard to intonation, loudness, tempo, and timing precision. Headset microphones were used to record each chorister separately while the collected sound of all singers was presented via headphones exerting acoustic s...

this study sought to investigate the impact of teaching speech acts and role relations through authentic audio-taped and video-taped materials on the level of iranian efl learners’ pragmatic competence. to this end, 55 intermediate learners were ed and randomly assigned to two experimental groups: the audio-taped group and the video-taped group. during the treatment, the audio-taped group recei...

The vital role of honeybees in pollination and their high rate mortality the last decade have raised concern among beekeepers researchers alike. As such, robust remote sensing beehives has emerged as a potential tool to help monitor health honeybees. Over decade, several monitoring systems been proposed, including those based on in-hive acoustics. Despite its popularity, existing audio-based do...

Spatial audio, which focuses on immersive 3D sound rendering, is widely applied in the acoustic industry. One of key problems current spatial audio rendering methods lack personalization based different anatomies individuals, essential to produce accurate source positions. In this work, we address problem from an interdisciplinary perspective. The strongly correlated with shape human bodies, pa...

The detection of sound events is a key technology for a various set of audio applications. Sounds are able to transport information through vision borders. Therefore, a humanoid robot assigned with kitchen tasks improves its interactive behavior with the environment a lot when using acoustics. While audio scene analysis employs a lot of subjects, this thesis deals with the recognition of preseg...

Recent advancements in multimedia technologies, such as LED integrations, advanced acoustics, and virtual reality applications, are revolutionizing stage design, underscoring an era of sophisticated technological implementation. This study, delving into prominent productions like the Han Show Wuhan The House Dancing Water Macau, critically examines infusion elements their transformative effect ...

acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

Periodic structures composed of quarter-wavelength or Helmholtz resonators have been widely used in the design acoustic metamaterials. An interesting phenomenon achievable through hybridization such is slow sound, which results from strong dispersion produced by local resonances. It gives rise to many applications as deep subwavelength sound absorbers metadiffusers. All proposed so far analyzed...
