How loud is it, really?

QuietScore ranks 883 appliances by their certified lab-measured sound levels — pulled directly from the U.S. EPA ENERGY STAR database and refreshed automatically. No marketing claims, no "whisper quiet" adjectives. Just sones, decibels, and airflow you can compare across every brand.

Bathroom & Utility Fans

811 models ranked · quietest: 0.1 sones · median: 0.7 sones

Range Hoods

72 models ranked · quietest: 0.1 sones · median: 1.5 sones

Sones → Decibels

What sones mean, how they convert to dBA, and what each level actually sounds like.

Why certified data instead of reviews?

Manufacturers describe nearly everything as "quiet". The only numbers you can trust are the ones measured in a certification lab under a standard test procedure. ENERGY STAR requires certified sound-level testing for ventilating fans and range hoods, and publishes the results as open data. QuietScore normalizes that data, ranks every model, converts sones to approximate decibels, and links each spec back to its official source — so you (and your favorite AI assistant) can verify every number.

How this site stays current

An automated pipeline re-checks the EPA dataset weekly. New certified models get pages within days of publication, discontinued listings are flagged, and every page shows when its data was last verified. Read more in our methodology.
