Loudness of different sounds was measured in order to evaluate Zwicker’s and Moore’s loudness models (published in Acta Acustica [3] and in the J. Audio. Eng. Soc. [4]). The test signals were synthesized bands of noise and environmental sounds. For synthesized noises, Zwicker’s model fits highly well with subjective results, it is a little bit closer to the data than Moore’s. For environmental ...

INTRODUCTION Dynamic MRI analysis of phonation has gathered interest in voice and speech physiology. However, there are limited data addressing the extent to which articulation is dependent on loudness. MATERIAL AND METHODS 12 professional singer subjects of different voice classifications were analysed concerning the vocal tract profiles recorded with dynamic real-time MRI with 25fps in diff...

The human auditory system perceives sound in a much different manner than how sound is measured by modern audio sensing systems. The most commonly referenced aspects of auditory perception are loudness and pitch, which are related to the objective measures of audio signal frequency and sound pressure level. Here we describe an efficient and accurate method for the conversion of the sensed facto...

the aim of the present study was to assess the industrial noise pollution and its effects on the blood pressure of workers during activities intextile factory in ilam,which is situated in west of iran. a cross-sectional study was performed on a group included 81 workers and 30 people as sample and control group, respectively. a questionnaire was filled out and then the other measurements includ...

For the evaluation of soundscape the perception by the human being with respect to the auditory sensation is very important, which is also influenced by expectation, experience and context. The well-known A-weighted sound pressure level is a suitable predictor at higher levels to estimate a possible damage of the human hearing by sound. But at lower sound pressure levels annoyance cannot be suf...

The primary purpose of the present experiment was to test whether the binaural equal-loudness-ratio hypothesis (i.e., the loudness ratio between monaural and binaural tones presented at the same Sound Pressure Level, SPL, is independent of SPL) holds for hearing-impaired listeners with bilaterally symmetrical hearing losses. The outcome of this experiment provided a theoretical construct for mo...

Loudness as the perceptual correlate of sound intensity is formed by some neural processing along the auditory pathway from the cochlea to the cortex. The loudness of a sound is largely determined by its level. Still, there are several other acoustical factors like stimulus bandwidth, duration, modulations, as well as personal factors like, e.g., the individual hearing status, that may affect p...
