These happen as the bass in the car is high meaning that the low frequency at high volume creates air pressure in your car and and when you open your mouth to talk the pressure difference will affect your vocal cords ------------- Subwoofers

I was under the impression this had to do with the way we PERCEIVED the sound... you know intereference etc - but does it actually affect our vocal chords???

So that's why McLaren and I could almost not hear each other's voice in the JBL eyeballer Palio when it was here for the vaahan yatra last year. It was awfully loud too.

Ears are sensitive to distortion. So a speaker producing 100db at 10% distortion will sound louder than a speaker producing 110db at 1% distortion. What might have happened in the palio is that the sound was loud with little distortion and you only realised it when you spoke and realised you cant be heard.

This used happen a lot in my room. I used to have 2 JBL 2245 (10 cu. ft. B460) bass bins mated to MTMs using 8" Focal (8N515) and 1" Morel MDT33. Powered by many hundred watts. Friends used to come over and only realise the system was loud when they could not hear them selves speak.

No, I don't think so. I think this has more to do with Aural than Oral.

low_bass_makker · 6th July 2006, 18:24

thats why I said at 150db u cannot hear u will feel the sound orally........

navin · 6th July 2006, 23:13

I dont want to go anywhere near 120db leave alone 150db for any length of time.

feeling the sound "ORALLY"????? thats strange !!!!!!! never heard or realized such a concept...... is anyone here going to buy this???

gurudev LMB tujhe Saalaam; did you ever reached that 150db.... i'm feeling curious to know about it.....

jkdas · 7th July 2006, 05:50

once you reach 150dB plus,teh vibrationis so much that you cant speak even if you try,you will sound gagged: definition of orally

navin · 7th July 2006, 10:03

I doubt 150db can be reached with any semblence of good quality sound. The reason being that even if the equipment is capable of it the room, cabin etc.. will all be making their own "muzik".

Hmmm...
When i said Aural, i was referring to the aural (hearing) senses and the fact that your ear drum is probably being vibrated to a point where it is unable to respond to regular vocal stimulation.

That said, the chances of your feeling sound orally are a bit higher than anally.

Sam 140db is generally acknowledged to be the threshold of pain. 150db might destroy your hearing completely.

delu · 8th July 2006, 09:55

Precisely Navin; it is 134db (i.e. 100 Pa) not also 140db (reference wikipedia.org). BTW, 150db (or 630 Pascal) sound is equivalent to the sound produced by a jet engine and heard at a distance of 30 mts.

navin · 8th July 2006, 10:20

Delu,
1. I am a little dated
2. I doubt you can hear the difference between 134db and 140db and I dont suggest you try either.
3. My normal listening levels are about 75-80db when I want it loud I would consider 85db with peaks of about 95-100db. Any louder and sustained listening would be dangerous.

agreed navin.
