But what the present article supports is that it is indeed smell that is the clearest way that dogs recognize their owners and other familiar people. The decibel scale is incredibly large because ears are so sensitive to soundpeople with normal hearing can hear anything from a light touch on skin to the roar of a planes engine. Someone who can hear at 20,000 hertz is referred to in the research world as a 'dog'. (Hertz is a measure of the frequency of a sound, and the higher the frequency, the higher pitched the sound.)
