It's not just loud; it's got 58 chimes and 5 volume levels (from whisper-quiet 0 dB to wake-the-neighbors 110 dB), so whether you're throwing a party or just trying not to startle your cat, it's got you covered. And with a 600 FT range, it's like having eyes in the back of your head—even if you're upstairs binge-watching your favorite show.
