A major step has been made in the understanding of drums acoustics thanks to the Laboratoire de Vibration et D’ Acoustique (Vibration & acoustics lab) of the National Applied Science (INSA) engineering school in Lyon.
Two students have been modelling a snare drum with the intent of :
- Understanding how the air loading (coupling) was influencing the membrane behaviour in the case of 2 membranes instruments
- How the venting characteristics influenced the membrane vibrations
- Quantifying the mechanical mobility of a snare as a function of its venting system
Congratulations to INSA LVA for those progress !
