Inkjet printers are much quieter than needle printers

Evidence

The data displayed in Fig. 16.6 indicate that the loudness of different needle printers may differ by a factor of 2 (F versus B). An inkjet printer can produce a loudness about only 1/3 of the loudness of a loud needle printer (H versus F). — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
