They thus exhibit phase shifts that may lead to recombination of constructive and destructive ways thus causing a complete disappearance of the signal. The latter phenomenon commonly known as `fading' may affect the performance of mobile communication systems. The fading amplitude of the received ...
The level of noise around us is constantly increasing, and is affecting the quality of our lives. What causes the noise? What should be done about it? Give reasons for your answer and include any relevant examples from your own knowledge or experience. Write at least 250 words. Task 2 报...
Also, it aimed at formulating a multivariate model to portray the annoyances responses when different types of natural sounds were added to traffic noise. The findings arising from this study should provide more insights on open space planning in order to maximize the acoustic comfort in the ...

Also, there are diverse methods available to assess the noise generated by traffic. These methods are extensively using in various applications areas from noise assessments to innovative study. The methods employed generally based on the nature of the work and the materials on which acoustic ...

An assessment of the audibility of sound from human transport by breeding Weddell seals (Leptonychotes weddellii) Anthropogenic noise generated through travel in the Antarctic has the potential to affect the region's wildlife. Weddell seals (Leptonychotes weddellii) in particular can be exposed to...

(e.g., S) are greatly distorted because the articulating air escapes through the nose before it can produce the characteristic hissing noise at one of the places of constriction. The child with an unrepaired cleft palate seems unconsciously to attempt to overcome these mechanical limitations in ...
Neurons are the computational elements that compose the brain and their fundamental principles of activity are known for decades. According to the long-lasting computational scheme, each neuron sums the incoming electrical signals via its dendrites and w
