Origin of Labor Headphones

First, early protective measures: In the late 19th and early 20th centuries, industrialization led to a significant increase in factory noise. Workers began using simple earplugs or pieces of cloth to minimize the impact of noise on their ears, but these measures had limited effect.
Second, First Patents: In the early 1900s, American inventors designed the first patented earmuffs for industrial and military use. These early earmuffs were primarily used to protect workers' hearing, but were still relatively primitive in design and materials.
Third, mid-20th century development: With World War II, military needs drove the development of hearing protection devices. At this time, more material and design innovations were applied to earmuffs to improve their comfort and effectiveness.
Fourth, late 20th century standardization: Between the 1960s and 1980s, governments began to develop hearing protection standards and regulations as occupational safety and health awareness increased. At this time, the design of labor protection headphones became more scientific and standardized.
Fifth, the modern labor protection headset: into the 21st century, with the advancement of material science and acoustic technology, the modern labor protection headset has become more lightweight, comfortable and efficient. Some high-end models also integrate active noise cancellation technology, which can reduce noise more effectively.
In summary, the development of labor protection headphones has evolved gradually with industrialization and the growing need for hearing protection, from the initial simple earplugs to modern high-tech earmuffs, whose design and functionality continue to improve to better protect workers' hearing health.
