As unimposing as it might seem, this subject more and more becomes an explosive issue, since

• efficiency requirements increase - entailing an increase of the acoustic emissions, but
• industrial safety regulations are continuously tightened (cf. EG directive "Noise at workplaces", EG-directive 2003/10/EG)

• Measurement and assessment of sound radiation of machines and plants
• Determination of sound power (DIN ISO 3743/3744, DIN ISO 9614)
• Determination of the principal sound sources, radiating surfaces, transmission routes
• Location of sound sources by sound intensity analysis or acoustic near-field holography
• Available instrumentation
  • SENSOUND
  • Scanning laser vibrometer
  • Sound level meter and analyzer

• Application of acoustic design rules
• Conception of primary and secondary noise reduction measures
• Design optimization by acoustic simulation
• Development of active noise reduction systems
