To give an idea of how loud this is, a normal and civilized conversation is around 60 decibels. This is also an important reference value, halfway between the limit of audibility and the limit of pain (120 dB). Normal breathing emits 10 dB, a soft whisper 30 dB, and a relaxing rain ...
What are decibels? When we talk about sound levels, we talk in terms ofdecibels (dB). Like our hearing, the dB scale is logarithmic, so every increase of 10dB represents an increase in sound pressure by a power of 10 and an increase of perceived loudness by roughly a factor of two. F...
