Hi there
I'm working on a research project regarding people with severe hearing impairment & hearing aids. For this we will be building an installation with several speakers and a projector + (acoustically transparent) screen. We need as little background noise as possible for accurate measurements. I'd like to get some advice from people who have more experience with this (I've honestly never bought a projector before and neither have my colleagues)
To sum up what I know so far:
As far as I understand, the best option when it comes to noise-reduction for projectors is a LED projector. Due to the size of the room we'll be doing this in, we will have to use a short throw or even ultra st. Image quality is less important than the noise but still relatively important, I think a resolution of 1280x800 should be alright but full HD would be better. Amount of lumen aren't a very big deal since the room will be obscured.
After looking around for a bit, those criteria gave me the Philips Screeneo series - there's only one problem, we'd like to output to a width of 3 meters. The Screeneos have a max size of 2,54m which I assume is the diagonal? So we'd have to stretch our image quite a bit which doesn't seem very ideal. Or would the loss of quality be negligible?
A non LED solution I found is the OPTOMA EH200ST , which claims to have a noise output of 26dB. Is this true though? Or is it just the noise during low-intensity use? It's really important that the device doesn't suddenly start heating up and getting louder in the middle of a session. A hushbox is an option to cover this, but I'd rather have a low-noise device to begin with.
Any help or advice is appreciated, thanks.
