The average noise level of projectors of a similar spec and age to this projector is 35dB, and the noise levels range from 30dB to 37dB. The Epson 536Wi has a very loud noise level (37 decibels) compared to most of the other data projectors that came out around the same time as this projector.
We think you might also be interested in some of the alternative 37dB noise level projectors currently available including because of its better review score, the Epson PowerLite 535W.
Data projectors with a louder noise level that might be worth looking at include the EB-535W (£675.56) (37dB), or the EB-530 (£695.15) (37dB) both from Epson.
