Weber, Ernst Heinrich

   Also found in: Encyclopedia 0.07 sec.

Weber, Ernst Heinrich (1795–1878)

German anatomist and physiologist. He applied hydrodynamics to study blood circulation, and formulated Weber's law, relating response to stimulus.

Weber's law (also known as the Weber–Fechner law) states that sensation is proportional to the logarithm of the stimulus. It is the basis of the scales used to measure the loudness of sounds.

In 1825, with his brother Wilhelm Weber, he made the first experimental study of interference in sound.
