Projectors get a bad name because of the amount of noise produced when in operation. Because a loud projector can be distracting and annoying.
Projectors are not inherently noisy but there might be several factors that might cause them to be.
There are several types of projectors and in this article, we are focusing on laser projectors – one of the most popular projector types for home, office, etc.
And answer the question – are laser projectors quiet?
Are Laser Projectors Noisy?
No, laser projectors are not noisy. Laser projectors produce the least amount of heat from the projection bulb or lamp amongst all projector types.
The fans don’t have to work hard to cool the lamp resulting in a quieter operation and less noise.
How Loud Is A Laser Projector?
Laser projectors are not loud and are barely audible when working.
Which Projector Is Quietest?
Because there are so many laser projectors. It’s difficult to know the quietest one. Fortunately, we have compiled a list of the best silent projectors.
Are Home Projectors Loud?
It depends on which type of home projector you choose. There are currently five types of projectors: DLP, LCD, LED, LCOS, and laser.
LCD and laser projectors are the quietest types out of all the projectors. But laser home projectors have the advantage of long lamp hours (7000 hours plus or more) and are quietest.
Choosing a home projector that produces a lot of heat is going to produce a lot of noise. Because the fans have to work extra hard to cool the projector.
Is It Normal For Projectors To Be Loud?
No, the harder the fan has to work the louder the projector. A sound of 70 dB (decibels) is considered loud or noisy.
Projectors that exceed the limit can be considered loud. However, depending on your hearing a projector of 50 dB might be sound loud or quiet.
Another thing to consider is if your projector became louder as months or years went by. If you notice this happening then there might be a few things that are causing it to be loud.
Just like how computers start to overheat or get very hot when they get dusty. The same also applies to projectors.
Dust blocks the vents of a projector causing the fans to work hard to get rid of the heat generated.
The same amount of heat that took less work for the fan to get rid of now requires more energy to do so. The extra work done by the fans is accompanied by loud noises.
The higher the temperature of the room. The hotter the projector will be which in turn makes the fans work hard to cool the device.
Another reason your home projector might be loud is old age. Just like human beings, devices are susceptible to old age and can easily break down if not maintained properly.
For example, on the outside, everything might look fine but there can be a hardware problem that’s causing your projector fans to work at high speed at all times.
How Can I Make My Projector Sound Quieter?
There are a few ways to make your laser projector quieter:
Projectors will accumulate dust and dirt as time goes on. Dust and dirt block the vent which are pathways for hot and cold air.
You have less cold air coming in and at the same time, fans have to work hard to get rid of the hot air generated.
This causes the projectors to make a lot of noise because of the fans. Regularly, cleaning the projector prevents the accumulation of dust and dirt keeping the vent free and open.
The fans then do not have to work twice, thrice, etc. as hard resulting in a quieter operation.
Get a New One
Old projectors can make a lot of noise. If you have cleaned your projector, made sure everything is working fine and it’s still loud.
Then it’s time to get a new one. The hardware may have worn out and mechanical processes are not as efficient as before when it was new.
Getting a new laser projector will always result in a drastic reduction in loudness compared to an old one.
Make Sure Your Room Has Good Ventilation
Hot rooms cause the projector fans to run at high RPMs (rotation per minute) to cool the projector creating loud sounds as a byproduct of their work.
If a fan cannot properly cool the projector, it will shut down.
That’s why making sure your room is properly ventilated is paramount in ensuring the quiet operation of your projector.
