Early Development of Labor Headphones

I. Background and development
At the beginning of the 20th century, as industrialization accelerated, the problem of noise in working environments such as factories and construction sites became increasingly serious. Prolonged exposure to high decibel noise can cause irreversible damage to hearing, so the need for labor protection headphones gradually emerged.
II. Early hearing protection
The earliest hearing protection devices were not headphones, but simple earplugs, and in the early 1900s, wax or cotton earplugs were used to attenuate noise. As technology progressed, advances in materials science allowed for the development of more effective hearing protection devices.
III. The Birth of the Modern Labor Headset
The first modern labor protection headset was born in the mid-20th century.In the 1950s, the U.S. Air Force and Navy developed more advanced over-the-ear hearing protectors when they needed efficient hearing protection in aviation and combat environments. These devices not only had to attenuate noise, but also ensure wearing comfort and communication.
Specifically, 3M was one of the key early developers of highly effective labor protection headsets.In the 1960s, 3M introduced the Peltor brand of earmuffs, a product that has gained widespread acceptance and use in industrial and military applications.
