Semon Law

Semon's Law is a law named after the English otorhinolaryngologist Frederick Semon (1849-1921), also known as the Semon-Rosenbach law. This law describes the relationship between the frequency of sound and the location where the eardrum vibrates when a sound stimulus occurs.

According to Simon's Law, high-frequency sounds cause the eardrum to vibrate at the top of the eardrum, closer to the ear canal. Low frequency sounds, on the other hand, cause the bottom of the eardrum to vibrate. This is due to the different stiffness of different parts of the eardrum.

Semon's Law is important in medicine because it allows for a better understanding of the anatomy and physiology of the ear. It is also used in acoustics and sound recording to determine the frequency response of microphones and audio equipment.

In addition, Semon's Law has practical application in the diagnosis of hearing impairment. The use of tone audiometry, based on Semon's Law, makes it possible to determine the damage to the auditory function and assess its degree.

Thus, Semon's Law is an important law that has wide application in medicine and acoustics. Its discovery and research by Frederic Semon allowed us to better understand the anatomy and physiology of the ear, as well as to develop new methods for diagnosing and treating hearing disorders.

Semon Law (1849–1921) - English otorhinolaryngologist who discovered and described the physiological mechanisms underlying the development of back pressure on the eardrum during eustachian tubal outflow.

Semon was one of the first researchers who began to study the physiological processes occurring in the Eustachian tube. He discovered that eustachian tubal drainage causes back pressure on the eardrum, which can lead to damage.

In 1895, Semon published his work in which he described this mechanism and called it “Semon’s Law.” In this work, he also proposed methods for treating eustachitis, which are still used in medicine today.

Semon's discovery was an important step in the development of otorhinolaryngology and helped to understand the physiological processes occurring during Eustachian tubal outflow and the treatment of eustachitis.
