Noise control of computers-application of optimal sound isolation layers and fun rotation speed
 Kunovský, Martin ; Mišun, Vojtěch (referee) ; Pellant, Karel (advisor)
This thesis deals with the distribution of noise in the computer case and radiation into the neighborhood. Influence of geometrical shape and size of the computer case on radiated noise from the computer was investigated as well as effect of placement of the fan. Reducing noise by using sound absorbing material into computer case and result of the suitable position of the computer in the working environment were also tested. Simulation of the noise diffusion and effectivity of anti-noise equipment was executed in Ansys FEM program.

Noise control of computers-application of tuned reflective absorber
 Plch, Radim ; Dušek, Daniel (referee) ; Pellant, Karel (advisor)
Presented bachelor thesis deals with the causes of noise in PCs and a posibility of noise reducing, using reflective silencers. A debate is conducted on the effectiveness and impact of anti-noise measures used in the inner area of the computer, with a focus on tiling the walls of internal computer chassis. For the purpose of the work was used sound meter.
