In real world how do you make sense of these sound pressure levels say to determine if an equipment if acceptable eg a fan. I usually get sound power (LWA) from manufacturer and it really does not make sense to me especially when there's no distance specified from the source eg 45dBA at 1m

Given a sound power value, the sound pressure/sound intensity can be determined at given distance from the source as explained in section 3.2 of this article: community.sw.siemens.com/s/article/sound-pressure-sound-power-and-sound-intensity-what-s-the-difference. Sound pressure and sound intensity levels are the same if the sound emitting object is in a free field.
