[ELI5] How does something reach negative decibels?

595 views

Microsoft made a -23 decibel room, but how does that work exactly? Once something hits 0 decibels how exactly can we measure it getting more quiet than that?

The decibel scale is logarithmic so a change of 10 dB represents a doubling or halving of sound intensity.

That being the case 0 dB is half the sound intensity of 10 dB and -10dB is half of that and so on.
