With a noise level of 35 decibels, the Sony VPL-GTZ270 projector has a quite loud noise level compared to most of the other latest 20000:1 contrast ratio projectors. The quietest noise level of newly released similar spec projectors is 22dB, the loudest is 37dB, and the average noise level is 31dB.
We compared all the other 35dB noise level multimedia projectors to this projector and we think because of its better review score, the Acer Z650 (£721.59) is also worth considering.
If you would consider a data projector with a louder noise level then you might want to look at the Optoma W340 (£460.74) (34dB), or the Panasonic PT-RZ475E (£5,852.40) (35dB).
