1. Rated in accordance with AHRI standard 270 (2015). AHRI Standard 270 establishes a method of rating outdoor unitary equipment in terms of Sound Power.
2. Rated in accordance with AHRI standard 275 (2018). AHRI Standard 275 provides the calculations for estimating the A-Weighted Sound Pressure at a given distance from the equipment. That is a more useful number because that is what humans will hear.
3. Based only on distance factor; other factors may change this value such as:

• Unit location (reflective surfaces adjacent to the unit)
• Barrier shielding sources
• Sound path/elevation
• Outside noise sources
