i went to sleep

[fruitsalad]

with earplugs in last night, and the sound of my heart beat woke me up this morning, why would i be able to hear my heart beating because i have earplugs in any one know?

[sticky vicki]

no

[B00]

what a concise answer vicki, did that mean no you can't hear your heart beating or no you don't know?

[sticky vicki]

yes

[stewey]

Essentially, the rebounding resonance of the systolic mitral valve is the same ocisloscopic pattern of the frequential modulation of the reboundation echo of the BBC station to which you were tuned.

[fruitsalad]

knew i could rely on you clever abers to know, bit technical for me stewey but thanks for trying.

[sticky vicki]

Thats what I just said

Seriously though, the carotid artery, quite a large artery, is routed almost over the inner ear. When wearing sound restricting devices, eliminating outside sound, one hears the pulsing of the blood through this artery.

Glad to help you, fruitsalad. It's the same principle, acoustically speaking, as sticking a finger in each ear and being able to hear a sea-shell.

[fruitsalad]

thank you Clanad

[stewey]

Don't I pretty please get two stars for being within a heart beat of the correct answer?

[fruitsalad]

oh go on then

[stewey]

Ta very much, fruitsalad. I'll put them in me 'star-jar' ready to spend if I ever get sent to AB Dungeon!
