5000:1 contrast ratio multimedia projectors that have been on the market for around the same time as this multimedia projector have noise levels of between 29dB and 48dB. When compared to other 5000:1 contrast ratio multimedia projectors that were released more than two years ago, the Z8150NL's noise level of 40 decibels is one of the loudest.
We compared this projector to all the other 40dB noise level multimedia projectors and we think the Epson Z8455WUNL which has better reviews is also worth considering.
Projectors with a louder noise level that might be worth looking at include the Optoma EH7700 (£4,990) (39dB).
