Vibration Measurements

Our company is equipped with high tech vibration measurement equipment. We continuesly invest in Research and Development activity in regards with innovative vibration isolation products. This also improves our accurate product customization and production, in order to offer our clients the best vibration control solutions, covering even the most complex requirements!

Our vibration measuring equipment consists of highly specialized precision tri-axial accelerometers (1v/g), targeted specifically for measurements in building vibration. In addition, we use industrial-type accelerometers to measure vibration on machines. Some examples are: generators, chillers, air handling units, gen sets, boilers, HVAC etc. These instruments simultaneously measure acceleration/velocity/displacement relative to the time and frequency domain.

Some indicative applications for vibrations measuring:

  • Measurement of machine vibration before and after the application of vibration control products.
  • Vibration measurement in buildings (ground-borne and structure borne vibration) generated by mechanical sources, or traffic (train) excitations.
  • Protection of sensitive appliances, measuring the machinery excitation frequency (i.e. sensitive electronic appliances on ships etc).
  • Human response to Vibration (H.R.V.) assessment in work places.
  • Prototyping & testing of new products.
  • Quality control.

Impact Sound level measurements (with tapping machine)

Impact sound level measurements in building’s floors with different coverings, using a tapping machine in accordance with EN ISO 140-7: Field measurements of impact sound insulation of floors.

The method is applicable to bare floors and floors with coverings. It evaluates the Normalized impact noise level (L’n), the Standardized impact noise level (L’nT) parameters and the impact sound attenuation index, ( ∆Lw).

The evaluation of the reduction of the Weighted normalized impact sound pressure level,( Ln,w ) by floor coverings on lightweight floors is based on EN ISO 717-2:2013: Sound insulation rating of buildings and of building elements. Part 2: Impact sound insulation

Research & Development

Our acoustic engineering team continuously carries out applied academic research on noise and vibration control projects. Therefore we work closely with specialized research National Institutes and Acoustic Laboratories. This contributes in designing innovative, advanced and effective, noise and vibration control solutions.

Vibration is our passion

Additionally, we carry out acoustic structural borne noise Insulation (Lnw) in Acoustic laboratories. As a result we can determine the characteristics of new, innovative eco-friendly sound deadening systems. In order to constantly guarantee high quality, we offer solutions that are tested and certified by independent acoustic laboratories.

Measurements of shear stress, compression and tension, for vibration spring mount, carried out by the National Technical University of Athens.

In order to optimize and document the damping behavior of anti-vibration pads, shear stress measurements were performed in shock load on the multidirectional vibration isolator Vibro-Foam 3D.F.
