At only 33 decibels, the Benq GP3 has a fairly quiet noise level compared to most of the other 10000:1 contrast ratio projectors that are a similar age to this data projector. Across all the comparable spec multimedia projectors that were launched around the same time as this projector the noise levels range from 28dB to 49dB, and the average noise level is 36dB.
We think you might also be interested in some of the alternative 33dB noise level multimedia projectors currently available including because of their better review scores, the W1400 (£599.95), or the MH680 (£607.98) both from Benq.
If you are not concerned about having a louder noise level then you might want to consider the Acer K335 (£609.97) (33dB).
