You might perhaps soon need to consult an ENT.

Quote:
Near-ultrasound sine-waves resemble the barely-audible "scream" of a
CRT monitor. These sound are hardly perceived as auditory, rather they
are mostly felt in the ear as pressure. If loud enough, this
near-ultrasonic sine-wave can actually be sharply painful -- like
sticking a needle into the ear. Is this tactile sensation due to
stimulation of tactile receptors in the eardrum or inner ear?

Do not deal with useless questions. Your outer hair cells are obviously
at risk to get permanently damaged. Given you will catch a tinnitus,
then try to be its friend, otherwise it will be terrrible.

It's not tht localized.

Since the feeling is more physical than it is sensual, one expects that
it is in the middle ear or eardrum.. likely the same nerves that an
earache would stimulate.

It does seem localized somewhere in the ear. If the near-ultra sound is
loud enough, the sensation becomes sharply painful [not at all
"aching"] -- like when an airplane descends. Otherwise is just feels
like a wierd sensation of pressure or penetration.

If you are feeling a sensation of penetration, it's not due to ultrasound
and it's not located in your ear.

Hi:

Why do my ears feel heavy when listen to an electronic dog-whistle
or
any sine-waves around that frequency?


Thanks,

Radium

P.S. Please respond with scientific answers and nothing else.


There are no scientific answers to nonsensical questions

This is not nonsense


Describe what you mean by your ears feeling heavy.

One might feel a sense
of pressure when listening to high levels of ultrasound just above the
upper
hearing limit, but I wouldn't call it a heavy feeling.

Yes. It does feel like pressure.

BTW, high levels of ultra sound can damage your hearing, so if you are
feeling any sensation, you're risking damage. In any event, why would you
be
"listening" to ultrasound?

I am just curious about the sensation. Why does ultrasound cause a
feeling of pressure in the ear?

The feeling of pressure only comes at relatively high sound levels, so it
you're feeling pressure, you're most likely causing damage to your hearing
mechanism. I suspect that the feeling of pressure is nature's way of warning
you that you're risking damage, even though you can't hear the sound.

I noticed the same thing many years ago when I first "heard" strong
ultrasound. The sense of pitch disappears altogether at frequencies
above our high frequency "cutoff", which can range anywhere from 12 kHz
for older folks to 20 kHz for some yougsters. I had termed it as an
"apparent pressure" at the time.

As "Ghost" says, there are no scientific explanations available yet.

My first impression was that it was just a partial or secondary
sensation that occurs for any strong physical stimulus where there are
no primary nerve sensors available. Just as a nearly frostbitten finger
can still feel some dull distubance sensation somewhere in one's hand,
but not any focused perception, since the primary sensors are numb.

Angelo Campanella

Sound waves do carry momentum in analogy to how electromagnetic waves carry

momentum. This momentum density can cause bulk streaming. It does not
explain Radium aberrations.

I have a FEELING it also occurs with lower frequencies assuming having a minimum level.

Dog whistles aren't ultrasonic - they tend to work in the 5-6kHz

range, so I imagine this is just a psychological thing - he is
depressed by the noise.
