I think the "original" question is: What is invisible that is material.Now sound we can capture a facsimile of by recording the sound . But does sound have a material quality ?
Sound has a material property in that sound is impossible without material to convey the vibrations that make up sound. You can hear sound if you put your ear up to a pipe and someone raps it...or hear sound through the air via the air molecules that transport it to the cilia (ear hairs in cochlea I believe) via your ear drum and bones. With no material to transport sound it cannot exist... as in outer space.
So how do one communicate from space to earth with sound? At its simplest, space communications relies on two things: a transmitter and a receiver. A transmitter encodes a message onto electromagnetic waves through modulation, which changes properties of the wave to represent the data. These waves flow through space toward the receiver. The receiver collects the electromagnetic waves and demodulates them, decoding the sender’s message. https://www.nasa.gov/feature/goddard/2020/space-communications-7-things-you-need-to-know
Definition of sound:
a : a particular auditory impression : tone
b : the sensation perceived by the sense of hearing
c : mechanical radiant energy that is transmitted by longitudinal pressure waves in a material medium (such as air) and is the objective cause of hearing
The wind is the movement of material. It is the movement of molecules through space. Wind does not exist in a jug as the molecules cannot move as typified by the definition of wind. Technically, air is always moving till it reaches a temp of absolute zero.The wind I would say is not material . Can you send me a jug full of wind ? But there is compressed air .
Definition of wind: natural movement of air of any velocity ....hmm, since air molecules move till absolute zero, this definition would include air in a jug...hmmm, possibly the definition needs clarity to include that it can be sensed by man unaided.... but I am cheated if I change what the dictionary says.
Jesus used the wind to illustrate how the Spirit regenerates. The wind is an element which man can neither harness nor hinder. The wind neither consults man's pleasure nor can it be regulated by his devices. So it is with the Spirit. The wind blows when it pleases, where it pleases, as it pleases. So it is with the Spirit. The wind is regulated by Divine wisdom, yet, so far as man is concerned, it is absolutely Sovereign in its operations. So it is with the Spirit. Sometimes the wind blows so softly it scarcely rustles a leaf; at other times it blows so loudly that its roar can be heard for miles. So it is in the matter of the new birth; with some the Holy Spirit deals so gently that His work is imperceptible to human onlookers; with others His action is so powerful, radical, revolutionary, that His operations are patent to many. Sometimes the wind is purely local in its reach, at other times widespread in its scope. So it is with the Spirit: today He acts on one or two souls, tomorrow He may, as at Pentecost, "prick in the heart" a whole multitude. But whether He works on few or many He consults not man. He acts as He pleases. The new birth is due to the Sovereign will of the Spirit ... author unknownJohn 3:8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
