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 16 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.
