Highly portable and very powerful sources for efficient on-site testing for the well being in buildings and working environments. Infra-Qsources proposes accurate and lightweight omni-directional sources, low frequency sources and reference sound power sources.
Qsources has developing and producing sound sources, shakers, sensors, etc. from 1992 onwards:
  • Some Qsources products have become the standard equipment for specilized NVH tests in the automotive industry world wide.
  • Building-acoustics sound sources which are by far the lightest on the market, with a performance level exceeding others.
Specialization and fast innovation has lead to proprietary and patented technologies in QSources products:
  • Efficient and powerful Lorenz drive systems in shakers and sound sources
  • Fully integrated high resolution sensors in sources and shakers
  • Unique self-suspending shakers with 6 degrees of freedom decoupling suspension systems
  • Power flow sensing for fast acting overload protection for sources and shakers

Qohm

The latest generation 4 inch drivers has now been built into the new Qohm sources. The weight is further down to 3.1 Kg.  The specification level is increased also; bringing the sound power level up to 123 dB Lw, and the 50 Hz band level up to 98 dB Lw which is the highest seen in the industry.

Qohm72

​High sound pressure levels for large site testing, and still single person portable. This source with a weight of 19.4 kg is capable of producing 140 dB Lw pink noise.
