A Sonometer is a device for demonstrating the relationship between the frequency of the sound produced by a plucked string, and the tension, length and mass per unit length of the string. This product is highly relevant for the study of acoustics, providing valuable insights into fundamental principles used in areas like musical instrument design and structural engineering.

In a physics lab, this device is used for demonstrating and experimenting with Mersenne's law, a fundamental principle in understanding how the frequency of sound waves relates to the length, tension, and mass per unit length of a vibrating string.
