Many people worry that the projector will generate a lot of noise and affect the viewing experience. is this real? Is the noise really that loud?

NEW YORK, USA, July 11, 2022 /EINPresswire.com/ — Where does projector noise come from?

Aerodynamic noise mainly comes from the airflow when the cooling fan stirs the air inside the projector and the friction between the object and the air.

The electromagnetic noise comes from the noise of the components on the main board inside the projector, which is what we often call the current sound. If you haven’t heard it, you can listen to the noise of the phone charger in a quiet environment while charging, which is electromagnetic noise. Electromagnetic noise is often more pronounced with some low-quality or cost-effective projectors.

Why is the projector making noise?
1. Appearance design.
In order to better fit into the home style, the projector body is usually designed to be more compact. The surface opening rate is low, which compresses the heat dissipation space.
2. High body heat.
The projector noise comes from the cooling fan. Once the projector body heats up high, the cooling fan needs to speed up the heat dissipation, and the noise will be louder.
3. The distance between man and machine is short.
Home projectors are generally placed on desktops, coffee tables, and bedside tables. The closer the viewer is to the projector, the more likely they are to notice the noise.

How to reduce projector noise as much as possible?
1. Ventilation and heat dissipation.
When the projector is in use, do not cover it with a dust-proof cloth, otherwise more heat will build up inside the machine, which will cause the fan to make more noise.
2. Regular dust removal.
Some people find that with prolonged use of the projector, the noise gets louder. Generally speaking, the longer the projector is used, the more dust will accumulate inside. Once there is too much dust, it will affect the heat dissipation of the projector. Therefore, it is necessary to regularly dust the projector to make the heat dissipation smooth and reduce noise.
3. Increase the distance between adults and machines.
If economic conditions permit, you can choose to install the projector in a ceiling-mounted way to physically increase the man-machine distance and reduce noise.
4. Replace the cooling fan.
If there is a problem with the cooling fan of the projector, it can make a lot of noise while it is working. If necessary, it is recommended to replace the cooling fan.

Final Thoughts on Buying Recommendations
1. When choosing a projector, pay attention to the fan design of the projector.
The design of the fan has a certain influence on the exhaust air. If the fan is designed at the bottom of the projector, it is not conducive to heat dissipation. Let’s take Dangbei Mars Pro as an example. The two side panels and the back panel contain vents for heat dissipation. The penetrating design can effectively improve air circulation and reduce heat dissipation noise. Operating noise as low as 24 dB.

2. Pay attention to the official noise decibel data on the product details page.

The official noise data is of course tested under ideal conditions, but can also be used as a reference. Generally speaking, the noise of smart projectors on the market today is generally controlled at 25-35 decibels.
3. Read more about real-world environmental measurements of noise.

Today, as projector technology becomes more and more mature, projector manufacturers are constantly improving parameters in all aspects, and noise problems are also being optimized. Many projectors on the market can be almost silent.
