This is the lowest sound level among the four capacities in the series, including the lower-capacity models. Still, you need to understand what this figure means and what it does not guarantee.\u003c\/p\u003e\n\u003ch3\u003eHow to read a sound level correctly\u003c\/h3\u003e\n\u003cp\u003eA level of \u003cstrong\u003e53 dB(A)\u003c\/strong\u003e is measured at a standardized distance, in free field, with the unit operating at full capacity. Three factors change what the neighbor actually perceives:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance.\u003c\/strong\u003e The level decreases by approximately 6 dB each time the distance doubles.

A unit rigidly attached to a wall or placed on a slab connected to the foundation transmits its vibrations through the building. The occupant then hears a low rumble indoors, which the level measured outside does not predict at all.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA real advantage of inverter technology is worth highlighting: the unit modulates. It operates most of the time well below its maximum capacity, and therefore well below its stated sound level. The 53 dB(A) corresponds to a peak, not its usual operating level.\u003c\/p\u003e\n\u003ch3\u003eOur placement guidelines in densely populated areas\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystematic anti-vibration mounts\u003c\/strong\u003e, and never rigidly fastened to the building structure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance from bedroom windows\u003c\/strong\u003e — both yours and your neighbor's.
