EPSON AMERICA, INC. EPSON Product Support Bulletin Subject: Quick Reference for Printer Acoustic Noise Levels Date: 6/5/91 Page(s): 1 of 2 PSB No: P-0016D Originator: SLS Sound intensity is measured in units called Bels (named after Alexander Graham Bell,) or more commonly in tenths of this fundamental unit: decibels. In making noise measurements a weighting network is applied in an attempt to match the frequency response of the instrument to that of the human ear. The most common is the A weighting network, with resulting measurements expressed in dB(A). The following is a list of current product's noise levels tested in accordance with standards set by the International Standards Organization (ISO). The acoustic noise levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ) mode using continuous paper and are not guaranteed figures. The acoustic noise levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode using continuous paper and are not guaranteed figures. The acoustic noise levels for the laser printers are averages while using single sheet paper and are not guaranteed figures. 9 PIN PRINTERS MODEL I LX-810 FX-850 FX-1050 I DFX-5000 I DFX-8000 1 NOISE LEVEL 56 dB(A) II 56 dB(A) 56 dB(A) I 55 dB(A) II I 55 dB(A) II 24 PIN PRINTERS LQ-510 56 dB(A) LQ-1010 56 dB(A) 11 LQ-850 1 56 dB(A) 11
