What happens is that the Air-waves issuing out of the Speaker's mouth, strikes the first layer of Air enclosed within the hearer's Tympanum and produces in the latter a peculiar modification whereby it is rendered capable of manifesting Sound and making it audible. To this end, the Mīmāṃsaka postulates the presence, in the ear-cavity, of the fixed layer of Air, for the purpose of affording a screen of resistance to the Sound-waves; against which screen these waves strike and thereby effect the change in the Auditory Organ. It is a well-recognised fact that Air cannot produce any effects unless it meets with a certain degree of resistance. Even though the Auditory Organ consists of Ākāsha, and Ākāsha is one only, yet the Ear-Drum is distinct in each person—each being limited in its power and scope by virtue of the Merit-Demerit of the person to whom it belongs. Then again, the change produced in the Sound-waves is not in the \*Ākāsha\* of the Ear, but in the Air enclosed within the Ear-Drum; and as this latter differs in each person, all men need not hear the Sound that may be heard by one of them. That all this diversity is due to \*Air-waves\* is also indicated by the fact that when Sound-waves travel with the wind, the Sound is heard at a greater distance than when they travel against the Wind. - [Previous: c19.10.3](https://indike.org/pramana/ins.religion.jha-1942.c19.10.3) - [Next: c19.11](https://indike.org/pramana/ins.religion.jha-1942.c19.11) - [Up: c19.10](https://indike.org/pramana/ins.religion.jha-1942.c19.10) --- Source: [https://indike.org/pramana/ins.religion.jha-1942.c19.10.4](https://indike.org/pramana/ins.religion.jha-1942.c19.10.4) · Pramāṇa
