A physical model of human Tympanic Membrane (TM), based on PDMS, as an easily accessible test platform for acoustic transducers was designed and fabricated. • A primitive ear canal simulator (TM holder) design was done using COMSOL FEA. • Vibration behavior of TM was tested with a Scanning Laser Doppler Vibrometer (SLDV). • Effect of an attached mass on the membrane was performed utilizing 32 mg and 57 mg accelerometers. • The model reproduced the basic vibrational characteristics of a human TM
