What is the dBA level (indoor/outdoor) mean?

Asked by: Opietaylor23
The dBA Level (Indoor / Outdoor) for the LG 18000 BTU Window Air Conditioner, Cooling & Heating, Model # LW1816HR are what are known as A-weighted decibels. A-weighted decibels abbreviated dBA, or dBa, or dB(a), are an expression of the relative loudness of sounds in air as perceived by the human ear. In the A-weighted system, the decibel values of sounds at low frequencies are reduced, compared with unweighted decibels, in which no correction is made for audio frequency. For example, normal conversation is rated at 60 dBA, so the indoor rating of 61 dBA for this Air Conditioner means that it will be slightly louder indoors as normal conversation. In terms of subjective loudness, a 1 dB change yields just over a 7% change...^IFV

I plan on placing this unit in a custom AC box, made out of aluminum. How much space is needed around the unit so it doesn't overheat?

Asked by: Geno900
The LW1816HR is designed for installation in standard single-hung or double-hing windows with actual opening widths from 29" to 41". The top and bottom window sash must open sufficiently to allow a clear vertical opening of 18" from the bottom of the upper sash to the window stool. This unit is not designed to be installed in any type of a sleeve or box as that will prevent proper operation and void its warranty. ^AC
