Ear Protection Protect BT|FM|DAB+, Kerbl Works

The Protect BT|FM|DAB+ hearing protectors by Kerbl Works are premium active earmuffs designed as a comprehensive solution for professionals working in high-noise environments. The product solves the problem of worker acoustic isolation by offering not only passive hearing protection, but also crystal-clear digital DAB+ radio reception, classic FM radio, and wireless Bluetooth connectivity for calls and audio streaming.

Application

The device is designed for intensive use in demanding industries:

• Agriculture and forestry: operation of heavy field equipment, chainsaws, and work in mechanized livestock buildings.
• Construction: operation of compactors, pneumatic hammers, and heavy construction machinery.
• Industrial workshops: long-term machining and grinding work.
• Working environment: locations requiring hearing protection while maintaining phone communication or access to radio information.

Principle of operation

The hearing protectors use passive noise attenuation through tightly sealed ear cups filled with specialist foam, supported by an advanced digital module. The DAB+ (Digital Audio Broadcasting) system ensures stable radio reception without interference, which is difficult to achieve with traditional analog systems inside steel structures. Bluetooth technology enables smartphone pairing, allowing users to answer voice calls through the built-in microphone without removing the hearing protection or interrupting work.

In practice

• DAB+ standard → guarantees superior sound quality and access to a wider range of digital radio stations, eliminating the noise typical of FM reception in demanding environments.
• Bluetooth (BT) → wireless freedom of movement; the phone can remain in a safe place (e.g., inside a tractor cabin) while calls are answered directly through the earmuffs.
• Protect series ergonomics → wide, soft sealing cushions evenly distribute pressure, minimizing discomfort even during full 8-hour shifts.
• LCD display → simplifies navigation between radio stations and provides information about battery level and active operating mode.
