With a noise level of 38 decibels, the Sony VPL-CH370 has a quite loud noise level compared to most of the other multimedia projectors that were launched more than two years ago. The average noise level of similar spec multimedia projectors that are a comparable age to this multimedia projector is 34dB, and the noise levels range from 24dB to 51dB.
There are a number of alternative 38dB noise level projectors currently available that you might want to consider including cheaper projectors such as the Sony VPL-CH350 (£1,268.02).
If you don't mind having a louder noise level then you might want to consider the Sony VPLSW536M (35dB and cheaper).
