QuietScore – Acoustic Quality Ratings for Denver Metro Buildings
https://getquietscore.comQuietScore rates apartment buildings for interior acoustic quality using a patent-pending algorithm, so you never move into a noisy building again.
Built because the most important thing about an apartment is invisible.
Walk Score tells you about the neighborhood. HowLoud tells you about street noise. Nothing tells you what happens inside the walls. That's the gap we built QuietScore to fill.
