Let’s talk audible noise! Audible noise is the amount of fan noise you can hear when the projector is on. Optoma claims the audible noise of the EH330UST is 33db at full power, 25db in ECO Mode. That’s about as loud as my home theater projector, which is to say, not loud at all. Sure, you’ll notice a hum, but it’s the kind of sound that disappears into the background the more you hear it – like air conditioning.
The projector will likely be wall mounted, and close to the screen surface. I seriously doubt any of those viewing in a classroom or conference room would be able to discern the noise, especially if, like most classrooms or conference rooms, there is some level of ambient noise. The presenter may be able to hear it, but it wouldn’t be loud enough to be distracting. And, if you’re showing a video or documentary, or your presentation has audio, you won’t be able to hear it at all.
That does it for our review of the Optoma EH330UST ultra short throw business and education projector! On the next page, I summarize everything you learned in the review, provide some insight as to the pros and cons to the EH330UST. See you on the last page!
