Background: Liver is an important organ that responsible for biological detoxification. There are few studies about the effect of co-exposure to organic solvents and noise on hepatic system enzymes. The study aim was to assess the effects of short-term exposure to noise and styrene on rat liver enzymes. Materials and Methods: In this experimental study, we studied the liver enzymes of male r...

Although the treatment and rehabilitation of the hearing handicapped have reached highly sophisticated levels, man should not be overly impressed with his achievements. Two recently recognized causes of deafness are a result of our mechanized and "advanced" society. In nature sounds occurring louder than 100 decibels (dB) are a rarity; such intensities when frequently presented to the hearing m...

The aim of this paper is robust identification of smart foam, as an electroacoustic transducer, considering unmodeled dynamics due to nonlinearities in behaviour at low frequencies and measurement noise at high frequencies as existent uncertainties. Set membership estimation combined with model error modelling technique is used where the approach is based on worst case scenario with unknown but...

Traditional denoising schemes require prior knowledge or statistics of the noise corrupting the signal, or estimate the noise from noise-only portions of the signal, which requires knowledge of speech boundaries. Extending denoising methods to perform well in unknown noise conditions can facilitate processing of data captured in different real life environments, and relax rigid data acquisition...

Noise emission will be a significant obstacle to the widespread uptake of unmanned aerial vehicles or UAVs. The assessment and mitigation UAV noise require validated modelling approaches. European Union has recently mandated an sound power measurement procedure based on for measuring machinery equipment. It is not clear if this legally provide useful data environmental This research aimed deter...

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Laboratory experiments which include the simulation of simultaneous exposure to the multiple traffic sounds and the assessment of subjective annoyance have been used to study the interaction between the noise sources, it’s influence on overall annoyance, and the modeling of exposure-response relationships. The aircraft (or railway) noise annoyance is masked by road-traffic noise and the higher ...

Structural equation modeling was used to analyze partial and total in situ annoyance in combined transportation noise situations. A psychophysical total annoyance model and a perceptual total annoyance model were proposed. Results show a high contribution of Noise exposure and Noise sensitivity to Noise annoyance, as well as a causal relationship between noise annoyance and lower Dwelling satis...
