In Croatia different folk singing styles have been inherited over long periods of time. To examine the differences between the klapa and dozivački styles of singing, singing voices of 12 professional male singers were digitally recorded and analysed for long-term average spectrum (LTAS) in the Praat program. All the singers were members of the LADO Folk… (More)
The idea of objective, computer based methods for testing audio quality is introduced in this work. Including some basic of perceptual coding, international standards and description of new measurement algorithm. With described algorithm PEAQ we have measured a characteristics of four different codecs and have shown the results in this paper.
The goal of this paper is to compare the results of reverberation time measurements obtained with different well-established methods used for this type of measurements, as well as some additional ones which could serve as in situ tool when standard methods are not available. The methods compared in this paper include integrated impulse response measured… (More)
In this work, an immunohistochemical study was performed to determine the distribution and relative frequencies of some neuromodulators of the digestive tract of silver catfish (Rhamdia quelen). The digestive tract of silver catfish was divided into six portions; the oesophagus, stomach, intestine (ascendant, descendant and convoluted segments), and rectum.… (More)
How the meaning a person gives to tranquility could affect the appraisal of the urban park soundscape. Abstract: Previous research has shown that tranquil areas in the city, such as urban parks, are usually perceived as positive and have a restorative effect on visitors. However, visitors could experience these spaces differently depending on the meaning… (More)
Urban soundscapes at five locations in the city of Zadar were perceptually assessed by on-site surveys and objectively evaluated based on monaural and binaural recordings. All locations were chosen so that they would display auditory and visual diversity as much as possible. The unique sound installation known as the Sea Organ was included as an atypical… (More)
This paper deals with the problem of voice activity detection in adverse acoustic conditions, namely high and varying noise scenarios. For robotic applications, we need the voice activity detector to be computationally light, robust to varying levels of background noise, and have a low latency, especially if we are tracking moving speakers. We analyze three… (More)
