Fig. 1 is a front perspective view of an embodiment of the soundproof cover for the Prinyota according to the present invention, with the lid open, Fig. 2 is a front perspective view of the same with the lid closed, and Fig. 3. is also a rear perspective view, Figures 4a and b are partial sectional views of the walls of the soundproof cover for printers of the present invention when soundproofing is performed using two-layer and three-layer laminates, respectively, and Figure 5 is a view of the wall of the soundproof cover according to the present invention. An explanatory diagram of the experimental set used to demonstrate the soundproofing effect, Figure 6 is 1 m long.
Figure 7 shows the time change in the noise level of the printer's generated sound at point S and the time change in the noise level when using the soundproof cover for the printer of the present invention.
The relationship between the center frequency and the noise level of the sound generated by the printer at point S and the relationship between the center frequency and the noise level when using the soundproof cover for the printer of the present invention, that is, the relationship between the center frequency and the noise level of the noise spectrum and background noise are shown.
