Quick Reference for Printer Acoustic Noise Levels

Date: 6/5/91

Page(s): 1 of 2

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.
