I think any kind of wave on the electromagnetic spectrum oscillates, be it visible light, X-rays, Gamma Rays, radio waves, microwaves, Infra-Red, Ultra-Violet. Sound waves have some similar characteristics, but sound and ‘physical’ vibration travel through a medium of dense “matter” to cause their effect. The EM spectrum isn’t necessarily non-physical or non-matter, but can work independently from dense matter - i.e. in the vacuum of space.
I think a similar question came up when one of the space probes recorded the “sound” of one of the planets, maybe Jupiter, and we talked about it on here or RR. It wasn’t really recording sound per se, as there’s no such thing as sound in the vacuum of space. It was recording EM waves from the planet’s magnetic field, and converting those into sound per an algorithm so humans could go “oooh, aaah”. If our planet vibrates in some way, through dense matter, it’s not “sound” until it hits the atmosphere and stimulates air particles which the human ear can detect. In other words, vibration or oscillation can occur without sound, and does so in many cases! Sound is only one possible expression.
The Schumann Resonance might be a good example of this? The SR is the result of constant vibration through the Earth of - I would guess - a type of P wave. It also interacts with the Ionosphere and would probably be audible if the frequency was higher. At 7.83Hz on average, it’s just not audible to human ears, but might be to some animals or insects. I believe it is at least partially caused by lightning strikes across the Earth’s surface, which generate the vibrations and the “resonance” created from them.
Supposedly, the ancient Vedic practice of meditating on “OM” or “Aum” came from the perception of this planetary vibration by sages and rishis in deep meditative states.
