Applied Acoustics

Working Group 1.72

Profile

  • Research and development on metrology in applied acoustics
  • New and further development of methods for the measurement of acoustic indicators such as sound power, sound absorption and sound reduction index
  • Experimental, numerical and analytical investigations on the uncertainty of acoustic quantities
  • Realisation and dissemination of the unit for the quantity airborne sound power
  • Quality control in applied acoustics, among other things by organisation and participation in interlaboratory tests
  • Protection of public and PTB interest in (standardisation) committees
