When ones Hyperacusis is bad..
And the sounds/volume is turned way up and heard as super loud.
It's possible that a person can actually hear and expirence the source it comes from as well.

The rumbling vibrational hearing of sound..
The vibrational noise that emits the sound out of it's bounds..
Engines/ motors, traffic, bass, beats, power tools anything that has a vibrational sound quality to it can be heard really well with hyperacusis disorder..

When my hyperacusis improved and the loudness of it all improved as well..
The vibrational hearing of sounds improved also..

One can also feel vibrations of sound as well because we hear not only through our ears but through our very bones..
Our very bones can be a conductor of sounds..

Bone conduction is the conduction of sound to the inner ear through bones..
There are several products on the market that exploit the bone conduction transmission pathway for sound.
Ones that use sound vibrations through the skull bone..

With hyperacusis disorder that can be all turned up without
haveing to use any product at all.

Acoustic Trauma: Bioeffects of Sound

"…any unwanted sound, soft or loud, sweet or nasty, creates a multidimensional envelope that does more than intrude -
it takes over not only your acoustic space, but your mind space as well.
Acoustic intrusions reduce your freedom of thought. There is no escaping sound.
It meets your body and forcibly enters your mind, not just through your ears but also via your bones, your flesh, and your body cavities."

"But much more sinister are the unnoticed effects of infrasound at lower levels:
in an ordinary car travelling at speed the infrasound noise is more than enough to mimic the effect of drunkenness in the driver.
With the sense of euphoria that infrasound also induces, it may therefore be responsible for many inexplicable crashes."

"Noise is violence: it disturbs. To make noise is to interrupt a transmission, to disconnect, to kill."

"Noise becomes a parasite which threatens to dominate the environment in the same way as weeds choke a vacant block"
