The Sonomètre of Loulié, or Loulié's sonometer, is a historical scientific instrument designed to measure sound frequencies. It was developed by the French physicist and musician Jean-Baptiste Joseph Sépulchre de Loulié in the 18th century. The device typically consists of a set of strings or wires that can vibrate at different frequencies, allowing users to analyze the pitch and tone of musical notes or other sounds.
