The meaning of a sound may influence its rating significantly. Therefore, a method was proposed, which removes the meaning of sound, keeping the loudness-time function the same. In essence, the sound is analyzed by FTT and, after spectral broadening, resynthesized by IFTT. Since it is impossible to remove the meaning of a sound, keeping all psychoacoustic magnitudes the same, variations are dis...

In order to verify the potential of proposed auditory display and sonification methods for aural analysis of textured images, a set of experiments was designed and was presented to 10 subjects. The results obtained and limitations of the methods are discussed. INTRODUCTION It has been shown that the auditory system is very useful for task monitoring and analysis of multidimensional data [1]. Ho...

background in many industries, noise is attributed as the most prevalent harmful agent threatening workers' health. geographic information system (gis) is an applicable surveying tool in civil engineering. but, the use of gis for noise and hearing loss screening seems to be partly a new approach. objectives this study aimed to apply gis in noise and hearing loss screening in the production hall...

Abstract Sound generating human activities so-called “anthropogenic sound” have increased ambient sound levels considerably in aquatic habitats that are markedly diverse in time and space. Sound generating human activities is now recognized as a potential driver of environmental changes in marine habitats. Iran has 750 km coastline along the Caspian Sea located in the north and around 2250 km ...
