There are two contributors to noise in a projector.
The main noise culprit in a projector is the fan. We all know that fan serve cooling purposes and are installed in a projector to help it cool when in use.
Not all noise in a projector is fan-based. One common source of noise in DLP projectors is the spinning color wheels.
What is the Quietest Projector?
The quietest projector on the market today is the Sony Home Theater Projector VPL-HW45ES.

Unlike with most projectors, you won’t need wall clearance with the Sony VPL-HW45ES as its fan exhaust is located at the front.

What Makes Projector Noisy?
Even with the quietest projector, some factors would affect the audible noises you hear.
The first is the location of the projector. There’ll be more audible noises if the projector is mounted 4.5ft directly above your head- than when it’s mounted at the back of your room at 6ft from you.
Low vs. High Lamp modes determine how quiet or loud a projector is. For example, a projector is quieter when on low lamp mode than when on the high lamp mode.
Unfortunately, most traditional projectors still make noise even when on the low lamp mode.
Your tolerance to noise also plays an essential factor in determining how noisy or quiet a projector is.
Some people have no problem with 30dB, while others will find it impossible to deal with noise at this level.

Quietest Projector Buyer Guide: Important Factors to Consider
There are factors to take into account before buying a projector. Here are the most important ones to ensure that you get one that meets your specific needs.
This is the main factor to take into consideration.
The quietest projector in this guide is the Sony Home Theater Projector VPL-HW45ES, with noise ratings of 22 decibels.
As earlier mentioned, quiet projectors should be in the range of 19-30 decibels.
The projectors in this guide have noise ratings in the range of 22-35 decibels.
The second quietest is Optoma HD39HDR Quiet Operation 26decibels.
If, after years, your projector starts making some weird noises- then chances are that- there’s dust buildup on the fan.
Keystone Correction and Resolution
Keystone is the ability of a projector to correct any image distortion when its placed off to the left/ right of the screen.
If you want a one for office use, then resolution shouldn’t be a problem for you.
However, if you want a projector for home entertainment, then it’s essential to stick with models with higher resolutions- i.e., 4k resolution.
Brightness and Contrast Ratio
Brightness is an essential factor to consider, especially if you’re going to set up the projector where there are lighting issues.
It’s measured in lumens, and the higher the number, the bright it will be.
The contrast ratio also plays an important role- it’s the difference between the brightest and the darkest areas of an image.
Most movies have these night scenes where it’ll be almost impossible to follow the action if you have low contrast.
Buy one with the highest contrast ratio to see detailed shadows and follow every bit of your film.
There are three light sources: standard, laser, or LED.
The standard types have 4000-5000 hrs when in eco and normal modes.
On the other hand, laser brighter than standard and LED models. Then there are LED projectors that can offer up to 20,000 hours.
LED types are the quietest since they are energy efficient and don’t produce too much heat.
