Bhṛgu–Bharadvāja-saṃvāda: Vānaprastha-parivrājaka-ācāra, Abhaya-dharma, and Lokānāṃ Vibhāga (Śānti-parva 185)
अव्याहतैश्लेतयते न वेत्ति विषमस्थितै: । आप्याय्यन्ते च ते नित्यं धातवस्तैस्तु धातुभि:
avyāhataiḥ śrūyate na vetti viṣamasthitaiḥ | āpyāyyante ca te nityaṃ dhātavas tais tu dhātubhiḥ ||
婆罗陀婆阇说道：“当与风相系的（听觉）作用不受阻碍，并与声恰当地相应时，人便能闻声而解其义；然而当此风之作用为墙壁或逆风之流所阻，遂成失调之态，则声不可得而知。又，作为声与诸根之所依、所生的身中诸成分，恒由彼等元素大种（bhūta）所滋养。”

Educational Q&A
Sense-perception depends on proper, unobstructed functioning of the elemental factors involved (here, the vāyu-related function enabling hearing). When conditions disturb that function, cognition fails; embodied experience is contingent and conditioned by the bhūtas and dhātus.
In a didactic exchange in Śānti Parva, Bharadvāja explains the mechanics of hearing: sound is grasped when the wind-related sensory function is unobstructed, but not when blocked by barriers or contrary air; he adds that bodily/sensory constituents are sustained by the elemental constituents.
