In short: Hisense rates the PX3 Pro at 32 dB operating noise (official data sheet, without picture mode or distance).
- That is quiet, but audible: during a film the fan disappears, in silent scenes you notice it – especially since an ultra short throw projector sits right in front of you.
- Its successor, the PX4 Pro, is as loud or about 2 dB quieter according to reviews. Its fan sounds deeper, the PX3 Pro's brighter.
- In its price class, only the LG CineBeam HU915QE claims less (30 dB). The quietest models on paper are currently far more expensive ones at 28 dB.
Who is it for? Anyone who wants lots of colour and brightness for the money and can live with a soft whir.
Noise check based on the Hisense data sheet and reviews, as of October 2026
Transparency: We have not measured the PX3 Pro ourselves yet. The figures come from Hisense's official data sheet and the reviews linked below. We will add our own measurements under our measurement protocol (German) once we have them.
How loud is the PX3 Pro?
Hisense Spain's data sheet lists the "Ruido audible" (audible noise) as 32 dB. As with most projectors, three details that matter for a comparison are missing:
- the picture mode (in bright modes the fan spins faster),
- the measuring distance,
- the A-weighting, i.e. whether the value is adjusted to human hearing.
So the figure is a guide, not a measurement for your living room. For context: a quiet living room at night sits at around 25 to 30 dB(A).
What does the fan sound like?
The most useful reviews put the PX3 Pro right next to its successor:
- ProjectorScreen.com found a difference of about 2 dB in favour of the PX4 Pro at the same distance. The PX3 Pro remained more noticeable because its fan sounds brighter.
- Klang-Galerie Nürnberg, a German specialist retailer, found the PX4 Pro no quieter in a direct comparison – just more even and without high-pitched components.
In short: in level, both are close. The PX3 Pro has the slightly brighter, more noticeable sound. If you are sensitive to noise, you will hear it more than its successor.
How to make the PX3 Pro quieter
- Darker picture mode: Filmmaker or cinema mode instead of maximum brightness lowers the fan speed.
- Keep the vents clear: the warmer the projector, the faster the fan. Don't put it in a closed cabinet.
- Solid furniture: a hollow TV stand can amplify vibrations. A heavy top or decoupling feet help.
- Seating distance: every doubling of the distance lowers the level by up to 6 dB.
- Sound louder than the fan: with a soundbar or the built-in Atmos sound, the whir disappears during a film.

Picture, sound and gaming
The PX3 Pro uses three separate lasers for red, green and blue. That gives very strong colours and a wide colour space. As with all DLP projectors, sensitive viewers may see rainbow effects, and depending on the screen a fine laser speckle.
Gamers get 240 Hz at 1080p and a low latency of 12 ms according to Hisense. The built-in 50 W Harman Kardon sound is enough for normal living rooms; in large rooms a soundbar is a sensible addition.
FAQ
Is the Hisense PX3 Pro loud?
No, but audible. Hisense states 32 dB. During a film the fan is hardly noticeable; in quiet scenes and at low volume it is more so.
Is the PX4 Pro quieter than the PX3 Pro?
Barely. Two reviews put it about 2 dB quieter, a specialist retailer found it no quieter in a direct comparison. The PX4 Pro's fan does sound deeper and more even, which makes it less noticeable.
Which laser TV is quieter?
On paper, several: BenQ V5010i and Formovie Theater Premium (28 dB each), the Epson EH-LS670 (29 dB(A), 20 dB(A) in eco mode, but at half the brightness) and, in the PX3 Pro's price class, the LG CineBeam HU915QE (30 dB). All figures with sources are in our noise database (German).
Verdict
At 32 dB according to the data sheet, the Hisense PX3 Pro is a quiet but audible laser TV. In noise level it is close to the more expensive PX4 Pro, whose fan mainly sounds more pleasant. If you want lots of colour and brightness for less money, the PX3 Pro is a good choice.
