In the later stages of development, simulation is a solution that can efficiently complement or even replace testing, enabling the detection of possible noise failures and the overall optimization of the final design. In the simulation the reference input signal x(n) is a white gaussian noise of power two-db generated using randn function in matlab, the desired signal d(n) ,obtained by adding a delayed version . Noise from the intake and exhaust lines contributes signifi¬cantly to the total noise level of passenger cars, motorcycles or utility vehicles acoustic simulation of duct, intake & exhaust . To accurately assess the acoustic performance of duct systems, both the air-borne noise propagating through the duct (known as pipe noise) and the structure-borne noise generated by the pipe .

In performance in terms of radiated noise the paper will also present the simulation tools provide a full analysis of the nvh behaviour throughout the design . Transmission loss is the key indicator of acoustic performance related to pipe noise one can numerically calculate the tl of a acoustic simulations of intake and . 1 noise health 2003 oct-dec6(21):3-16 the effects of background noise on cognitive performance during a 70 hour simulation of conditions aboard the international space station. The effects of background noise on cognitive performance during a 70 hour simulation of conditions aboard the international space station noise health 20036:3-16 how to cite this url: smith d g, baranski j v, thompson m m, abel s m. Or phase noise in the output of the pll used in these applications generally degrades the performance margins of the system in which it resides and so is of great concern to the designers of such systems.
