• Expert witness
• Measuring body according to §26 BImSchG for noise and vibrations

Low frequency vibrations may affect, for example, humans, buildings, production plants etc. and can cause miscellaneous disturbances, damages and impairments.

Low frequency vibrations often occur conjointly with low frequency noise and/or tactile (inaudible) subsonic noise. The transition to structure-borne sound is blurred.

Due to great wavelengths, resonance and partly very high induced energy, finding the cause is often difficult.

The department "low frequency vibrations" with its comprehensive experience and facilities offers effective solutions, especially for low frequency problems:

• vibration measurements
• vibration prognosis
• continuous monitoring with closed, signal triggering measuring facilities (e. g. SMS, e-mail, light signals upon overrun trigger values)
• multi-channel measurements
• safety at work
• vibration protection according to DIN 4150
• expert opinions in court
• conservation of evidence
• analysis of subsonic sound in conjunction with structure-borne sound / vibrations
• building dynamics (e. g. building vibrations, bell tower vibrations, elastic bearings)

We are a state-appointed measuring facility according to §§26,28 BImSchG and accredited in all 16 federal states for noise emissions and immissions, vibrations (emissions and immissions) and are regularly called upon as expert witnesses in court hearings.

Dipl.-Ing. Arno Schällig is responsible for the measuring body and the quality test center. In the frame of quality assurance we regularly participate in round-robin tests as well as comparative measurements for noise abatement.
