AB - Knitted fabrics can be made to vibrate as a speaker by laminating it with Polyvinylidene fluoride 
(PVDF)  strips  to  form  curved  arch  laminated  at  the  ends.  The  PVDF  strip  would  vibrate  due  to  the  piezo 
electric effect when a 200 Vrms voltage is applied.A two-dimensional analytical prediction model is created 
based  on  the  principles  of  stress  and  strain  behaviour  of  a  curved  laminated  arch.  The  model  predicts  the 
radial  displacement  of  the  arch  with  respect  to  the  frequency  of  the  excitation  voltage  of  the  PVDF  strips. 
The Sound Propagation Level (SPL) at a particular point from the arch surface is modelled as a simple sound 
source  in  an  infinite  baffle.  The  acoustic  pressure  is  linked  with  the  radial  displacement  in  the  model. 
Simulation is carried out on structural properties of the fabric to discern the resonance region of the speaker 
vital for Active Noise Control to reduce automotive interior noise.
