The future lies in tranquillity
Our audio systems with the pioneering ANCOR technology (Active Noise Cancelling Offered by recalm) are based on many years of analysis of numerous driver’s cabs in construction, agricultural and forestry machinery, trucks, aircraft interiors and more.
As a pioneer for audio technologies in vehicle guidance, we have worked closely with our customers to create innovative technology that is precisely tailored to the needs of drivers and meets the requirements for comfort, safety and state-of-the-art technology.
In addition to its noise suppression and entertainment function, ANCOR shines with improved communication: this not only simplifies work processes, but also ensures increased work safety.

Improved communication
in noisy environments thanks to the state-of-the-art hands-free system and clearly understandable radio communication.
Innovative hearing protection
Noise reduction of up to 50 % when guiding construction/agricultural/forestry machinery, trucks, cars, airplanes and more.
Individual audio experience
With music playback via Bluetooth or interference-free digital radio at a comfortable volume.
Our ANCOR technology solves these problems:
Noise-induced hearing loss is the most common occupational disease.
Noise-induced hearing loss
Across all sectors, hearing loss accounts for around a third of occupational illnesses each year. In addition to operators of construction, agricultural and forestry machinery, truck drivers and pilots are also affected.
However, high noise levels do not only affect hearing: Stress, mental illness, concentration disorders and increased blood pressure are further consequences. Our ANCOR technology can improve the health of your employees through noise protection and thus revolutionize occupational health and safety.
Discover how ANCOR is changing the market:
It is more difficult than ever to find skilled workers.
Skills shortage
In times of a shortage of skilled workers, attractive remuneration is no longer enough to find and retain competent employees. Employers need to create an attractive environment with a high level of working comfort in which employees feel comfortable and valued.
ANCOR offers machine operators the unique opportunity to customize their working environment and adapt it to their needs as a personal quiet zone.
Discover how ANCOR is changing the market:
In times of exploding costs, project delays must be kept to a minimum.
Project delays
Inflation, rising wage costs, legal requirements: these are just some of the factors that have driven up the costs of construction projects in recent years. This makes it all the more important that ongoing projects are completed without delays.
Communication is a particularly important factor on construction sites: poor radio signals and a high noise level due to machinery and construction site noise lead to communication problems. These can not only lead to delays and misunderstandings, but in the worst case also to accidents. Learn more now about how ANCOR is revolutionizing communication with machine operators.
