On previous occasions we have talked in depth about the teams of portable air conditioners, about how they work, what they offer, their advantages and disadvantages, even about tricks and tips to install them and squeeze their full potential.
And we saw how one of the main negative points of this type of device is related to the high noise level caused by its compressor, essential to generate the cold that helps us regulate the temperature of the room.
Are all models on the market equally noisy? Well no, there are some that offer lower levels than others, sometimes at the cost of a lower capacity to generate cold. That is why today we bring you a selection with the more “silent” equipment that we can currently find in stores.
How to rate noise in specifications
And we say “silent” in quotes because all, absolutely all portable air conditioners generate much higher noise levels to what we could consider as a really silent team, as for example it happens with the wall mount kits. Portable air conditioners are devices that offer noise levels above 50 dB (A), a figure clearly higher than the between 20 and 30 dB (A) of systems with compressor installation on the exterior wall of the house.
In addition, the real value of the noise generated is something that sometimes hard to find in advertising of the manufacturer, having to resort on many occasions to the instruction manual to find out and even in that case the brands may use “tricks” to hide the real noise level of the device.
For example, the most common is that they do not differentiate between “sound power level” Y “sound pressure level”. The former measures the noise emitted by a sound source, while the sound pressure level determines how much of that sound comes to a certain point at a certain distance.
Both are measured in decibels, but clearly the sound pressure level will always be lower because some of the noise fades along the way, this loss being directly proportional to the square of the distance. In addition, sound pressure levels are not always offered at the same distance, since there are brands that measure them at 1 meter, others at 2 meters and others do not specify how they measure it.
Therefore, when evaluating the noise level of one of these devices and especially to compare between several models, we must look at what figure the manufacturers are giving us, since the same equipment can offer very different values with figures of for example 50 dB for the sound pressure level and 65 dB in the case that they give their acoustic power value.
