HEAD acoustics - Supplier Focus

HEAD acoustics sets standards in high-end solutions for data acquisition, analysis and evaluation in the field of sound and vibration, telecommunication and audio quality.

Our systems enable a holistic understanding of sound and vibration phenomena and evaluating solutions early in the development phase by interactively experiencing measured as well as simulated sound and vibration. We offer cutting-edge testing technology for all types of speech and audio applications including solutions for realistic reconstruction of sound fields in a

controlled lab environment.

Our products are complemented by consulting and engineering services based on more than 30

years of experience in sound engineering for technical products, investigation of environmental

noise, speech quality engineering as well as consulting, training and support. The medium-sized

company from Herzogenrath, Germany, has subsidiaries in China, France, Italy, Japan, South

Korea, the UK and the USA as well as numerous sales partners worldwide.

SQuadriga III – Standard system

for mobile sound and vibration measurement


  • Mobile recording and playback system with numerous integrated interfaces for analog and digital sensor technology

  • Usable in stand-alone mode or as a data acquisition system in conjunction with a PC. Expandable with other modules for increased numbers of channels

  • Large colour touchscreen for configuration and evaluation

  • FlexRay & CAN FD

  • Modularly expandable with analysis functionality

  • Measurement chain validation as per Class 1 of IEC 61672 possible in front-end operation

Ever ready:

Thanks to a powerful battery and a multitude of integrated interfaces, the SQuadriga III compact handheld

system with its 8 analog channels and various digital inputs is ideal for mobile sound and vibration

measurements in any industrial application. It allows recordings to be made in any environment and also takes into

account the latest psychoacoustic findings for optimal sound design.

Measurement chain validation as per Class 1 of IEC 61672 is possible in front-end operation.

Integrated interfaces make additional adapters unnecessary. The highest-quality recordings are achievable using a binaural headset (e.g. BHS II) or artificial head (e.g. Head-Shoulder-Unit HSU III).

SQuadriga III features one integrated FlexRay connector and two CAN FD connectors. Three USB ports allow video recordings to be made or photographs to be taken via external cameras, e.g. to document the measurement situation.

The user-friendly look and feel of the SQuadriga III is rounded off by the 7-inch display with capacitive multitouch and intuitive operation. A powerful processor handles psychoacoustic analyses such as sharpness and loudness in addition to time signal, FFT and one-third octave band spectrum. The system operates silently and is ready to go in just a few seconds after switching on.
