Episode 2Greater wax moth hears up to 300 kHz, 'the highest recorded frequency sensitivity of any animal' (Moir et al., Biol. Lett. 2013)
Episode 3LIGO: detects a change of 1/10,000 of a proton's width over 4 km arms
But: Needs one of the largest vacuum systems on Earth, isolation, two or more sites
Episode 4Take away medium, organ, frequency band, competing voices, sound itself (50:16).
Not sharper hearing, but hearing without an ear, without air, without missing a whisper.
From the tradition: ʿĀʾisha: 'Praise be to Allah Whose hearing encompasses all voices' (Nasāʾī 3460; Ibn Mājah 188, ṣaḥīḥ). Bukhari 7386: 'You are not calling a deaf or an absent one'. al-Ghazālī: 'hears without earholes or ears'; he perceives 'the creeping of the black ant upon the rugged rock in a dark night'
