Ear Protection Protect BT|FM, Kerbl Works

The Protect BT|FM hearing protectors by Kerbl Works are advanced active earmuffs that combine the highest safety standards with modern communication systems. The product solves the problem of worker acoustic isolation by enabling simultaneous protection against harmful noise, wireless phone connectivity, and access to radio information, which is essential in the dynamic environment of modern agriculture and industry.

Application

The device is intended for professional use in environments with high noise levels:

• Agriculture: operation of heavy field machinery, tractors, and work in noisy livestock buildings.
• Industry and workshops: metalworking, woodworking, and operation of power tools.
• Forestry: protection while working with chainsaws and wood chippers.
• Working environment: places requiring constant phone communication while maintaining hearing protection.

Principle of operation

The hearing protectors work through passive acoustic insulation (wide foam-filled ear cups) combined with an active electronic module. The Bluetooth (BT) system allows pairing with a smartphone for music streaming and hands-free calls, while the integrated FM tuner enables radio reception. The control electronics allow adjustment of digital audio volume while maintaining the physical barrier that suppresses external sounds exceeding safe decibel levels.

In practice

• Wireless connectivity (BT) → allows users to answer calls without interrupting work or removing the hearing protection, improving safety and productivity.
• Entertainment and information (FM) → built-in radio with digital station search makes long and repetitive tasks more enjoyable.
• High wearing comfort → adjustable headband and soft sealing cushions provide even pressure distribution, enabling long hours of comfortable use.
• Kerbl Works durability → as “Animal Experts,” Kerbl designs equipment resistant to demanding farm conditions such as dust, moisture, and vibrations.
