| Of the wide variety of air conditioners used, the | | | | be traced back to a few reasons. First of all, not all |
| window air conditioner is the most popular. It definitely | | | | houses had the provision for ducts being installed. Even |
| sales more than the split air conditioners and are also | | | | if the house had provisions, installing ducts would be a |
| more widely used than central air conditioners. And this | | | | pretty expensive exercise. |
| is not just for domestic purposes only. Even | | | | So, before you invest on a window air conditioner, do |
| commercially, both for cooling and heating purposes | | | | check the labels on the unit or in the literature that |
| the window air conditioners are the most preferred. | | | | comes with the product to find out the sound power |
| The main reason for this is that it can fit into your | | | | levels. The noise level are generally represented in |
| window and most of its body remains outside the | | | | terms of the unit decibel. The higher the decibel ratings |
| room. So it looks good and also doesn't occupy any | | | | the louder the sound is. You also need to remember |
| space of the room. They also need not be shifted | | | | that the sound pressure increases by a factor of 10 |
| from one place to another. I t remains unobtrusive. | | | | for every 10-decibel increase. So, if we are talking |
| But, like any other air conditioner machine it also | | | | about 50 decibels then it is actually 10 times louder than |
| produces noise. The intensity obviously would vary | | | | 40 decibels and 100 times louder than 30 decibels. So |
| according to the type and size of the air conditioner, | | | | don't be fooled by thinking that 60 decibels would |
| but there will be some amount of noise produced. This | | | | hardly make any more noise than 50, cause it will |
| is kind of a white noise and though some might actually | | | | actually make a lot more noise. |
| like the noise, most would want to do away with it, or | | | | The source of noise in a window air conditioner is the |
| at least keep it to its minimum. And remember the | | | | compressor and the fan which are both combined in a |
| noise isn't restricted to your home alone, but can affect | | | | single unit. There may be other reasons to noise as |
| your neighbors. | | | | well like worn bearings, cabinet rattles, dirty or rusty fan |
| The ductless air conditioners basically are a derivative | | | | blades, worn rubber mountings and compressor wear. |
| from the central air conditioning system and the | | | | With regular maintenance you can keep these noise |
| window air conditioning system taking the plusses from | | | | levels down but you have to accept the fact that |
| both, and removing the restrictions of each. The | | | | after a point of time, as the air conditioner ages, the |
| necessity for inventing this ductless air conditioners can | | | | noise from it will keep increasing. |
