With a noise level of only 36 decibels, the Hitachi CP-TW3003 has a fairly quiet noise level compared to most of the other 5000:1 contrast ratio projectors that are a similar age to this multimedia projector. The average noise level of 5000:1 contrast ratio projectors that were released more than two years ago is 37dB, and the noise levels range from 29dB to 48dB.
We compared all the other 36dB noise level data projectors to this projector and we think cheaper data projectors such as the Hitachi CP-AX3003 (£866.18) is also worth considering.
Projectors with a louder noise level that might be worth considering include the Epson EB-4850WU (£1,318.15) (38dB), or the Ricoh PJ WX4240 (£1,299.99) (37dB).
