Acoustical Measurement of Sound System Equipment according to IEC 60268-21

KLIPPEL LIVE is an informative new webinar series as we continue to educate and support loudspeaker designers and manufacturers around the globe. To kick this off, we start with a 15 part series about using the IEC 60268-21 acoustical measurement standard, perfect for anyone working with speakers, headphone and other audio devices. 

 

This includes practical information regarding:

  • Quickly and accurately measuring in normal, non-anechoic rooms

  • Comprehensive distortion testing

  • Linking physical and perceptual evaluation 

Along the way, we give tips and discuss how to:

  • Interpret measurement results
  • Avoid pitfalls  

At the end of each live webinar, we will answer questions submitted by you, the viewer.
