Abstract:
Correct pronunciation of Qur’anic sounds is crucial, especially for elevation sounds such as /tˁ/ and /dˁ/. This study analyzes their spectrographic characteristics in Surah Al-Fatiha recitation by non-native Arabic speakers, as Indonesian speakers (Ummi teachers in Bandung), compared to native Arabic speakers. Using a qualitative comparative method with a case study approach, data from four participants (two males and two females) were collected through recording, listening, and transcription. The analysis uses Praat to examine parameters such as duration, fundamental frequency (F0), intensit

(Uploaded by Plazi for the Bat Literature Project) Abstract Acoustic signals play a crucial role in transmitting information and maintaining social stability in gregarious animals, especially in echolocating bats, which rely primarily on biological sonar for navigating in the dark. In the context of foraging without relying on tactile, visual or olfactory cues, acoustic signals convey information not only on food but also on ownership and defense of resources. However, studies on such information remain fragmentary. In the present study, we aim to document the social vocal repertoire of Myotis

Abstract:
Acoustic records were made from the sailboat "Leviathan II", in the area southwest of the "Choros" coastal island in the central-north of Chile, to test the feasibility of developing studies on the underwater sound production of the resident pod of bottlenose dolphins, Tursiops truncatus. While drifting and having the dolphins under visual contact, the recordings were made using the Ca20 wired hydrophone. A preliminary vocal repertoire was assessed to base further studies. The use of protocols for approaching the dolphins, register and analyze the information resulted in 296 whistles individua

Abstract. Barking in domestic dogs still remains a topic of controversial discussions. While some authors assess dogbarking an acoustic means of expression becoming more and more sophisticated during domestication, others name this sound type "non-communicative". Vocal repertoires as works on individual sound types are rare, however, and there has been almost no work done on Iow-intensity, close-range vocalizations, yet such types of vocalization are especially important with the more social canids, hence, with the human-dog-communication and understanding of dogs.

Purpose To analyse the immediate effect of a vocal warm-up program on children that sang in a choir by means of spectrographic analysis. Methods Experimental study consisting of 14 girls from an amateur children’s choir, aged 9 to 12 years. Acoustic spectrographic analyses were performed before and after a specific vocal warm-up program, consisting of a hierarchical sequence of body exercises, respiratory and articulation training, vocal exercises, ascending and descending musical scales and facilitating sounds. The speech material for spectrographic analysis was the sustained /Ɛ:/ vowel, pre

Abstract:
Background: The scalp-recorded frequency-following response (FFR), an auditory-evoked potential with putative neural generators in the rostral brainstem, provides a robust representation of the neurophysiologic encoding of complex stimuli. The FFR is rapidly becoming a valuable tool for understanding the neural transcription of speech and music, language-related processing disorders, and brain plasticity at initial stages of the auditory pathway. Despite its potential clinical and empirical utility, determining the presence of a response is still dependent on the subjective interpretation by a

Abstract:
AbstractSoundscapes have been likened to acoustic landscapes, encompassing all the acoustic features of an area. The sounds that make up a soundscape can be grouped according to their source into biophony (sounds from animals), geophony (sounds from atmospheric and geophysical events), and anthropophony (sounds from human activities). Natural soundscapes have changed over time because of human activities that generate sound, alter land-use patterns, remove animals from natural settings, and result in climate change. These human activities have direct and indirect effects on animal distribution
