A:Answer Hello there, Kate! Based on the Frigidaire specifications and manual data for the 10,000 BTU Smart Wall Air Conditioner (FHWW/FHSC series): Yes, it is considered fairly quiet for a wall-mounted air conditioner, but not “whisper silent.
Simple comparison
50–55 dBA → fairly quiet (normal bedroom use, noticeable but fine)
55–65 dBA → moderate noise (typical older/window AC behavior)
Your unit sits mostly in the “fairly quiet but clearly audible” range.
Bottom line
✔ Yes — it is fairly quiet for a standard 10,000 BTU wall AC
✔ Normal for it to produce a steady hum while cooling
❌ Not “silent” or premium ultra-quiet inverter level
