It's called exponential growth; if sound is increased up to 90 db with a megaphone, then the amplified sound should theoretically be multiplied by that amount of db for each megaphone, meaning it wouldn't stay the same... Theoretically

[@vincentrobinette1507]

This is exactly what I expected, and, you're exactly right about why it isn't that much louder. The amplifiers clip. The first megaphone is pretty loud, but still coherent. the next megaphone is louder, but clipped.(saturation distortion) After that, the rest are just a square wave, at the fundamental frequency of your voice. The first 2 megaphones are loud, the rest of the 8, are maybe half again louder, than the first two. As for breaking the wine glass, the only way that would happen, is if the resonant frequency of the wine glass matched the resonant frequency of the horn. Otherwise, there just isn't enough amplifier power, to do it. you would have better luck, finding the right note on a trumpet, that matches the resonant frequency of the glass, even though, the amplifier in a megaphone is ~10 watts, and a person can barely blow more than 1/2 watt into a brass instrument, breaking glasses is all about resonance.

[@a64738]

For every time you double the number of speakers you add 3db to the volume. It gets a lot of speakers real fast, after doubling it 20 times you have over 1.000.000 speakers... That is the number of speakers you need to go from 60db to 120db.

[@safi2852]

He's that guy in math problems buying 10 megophones.

[@MsHojat]

For the record permanent hearing loss occurs at virtually all sound levels, it's just that it needs to be sustained for longer periods of time -or more frequent- for it to do the same damage as a louder sound.

[@blueredbrick]

No, there is an offsett. Below this no damage of any sorts is endured by the hearing system. 'Virtually' does not do it.

120 is the amount of sound that a jet plain makes as it takes off and the volume at which I can shout without putting an exesive amount of strain on my self

[@jamil7891]

whats a plains don fly. planes do

[@sapago4166]

Shouting in someone's ear is 110 db. The loudest human voice recorded is 129 dB. (Jill Drake) Maybe plains make 120 db at takeoff, but a *plane* is closer to 150 dB at 25 meters. Any lower decibel readings were recorded at a distance of hundreds of feet. Why would it even be possible that you could make as much noise as a jet engine at takeoff? They are moving way more air than you could ever conceivably do.
