Is silence a fact or a feeling (?)...is it about acoustics or is it about aural capabilities...?
On a deeper thought...silence is all about cessation of vibrations...you could choose which one...!
In Sanskrit (संस्कृत) there is a word - 'spandana' (स्पन्दन) - which stands for quivering, palpitation, etc. and also connotes the beginning of life or the activity of the mind.
योगश्चित्तवृत्तिनिरोधः (yogah chitta vrtti nirodhah) - so says Patanjali in his Yoga Sutras. Vrtti connotes flutuations or movements. Chitta connotes mind, intellect, feeling of self - all inclusive. Yogah connotes union of the limited self with the supreme self - state of supreme bliss, peace, silence. Nirodhah connotes cessation.
So here lies the deeper meaning of silence and a hint to achieving the same by cessation of fluctuations, vibrations...
