I heard that a person got himself deaf by a telephone.I heared that his telehone was made inapropriately that it sent shockwaves and shock down his ears.His wife found him on the floor. I think that he spilt drink on cable wire or the telehone was program inapropriately that a person called and then voice program got funny and his eardrums was deaf by getting a severe shock to the eardrums then, he was deaf.  So, Mythbusters,can u test this myth with the new buster? plz i want to find out whether it is true. can u put this on your show?

The volume of a digital connection is limited. There's no way to exceed a certain volume! Since the telephone system is fully digital, there's no way to do that!
Back in the 50s, phones were connected more or less directly to each other (as long as not long distance). Here it would be possible to hook the line to a strong signal generator. But a telephone contains surge protectors and a protective rectifier which clips the signal in the earpiece if it becomes too strong. This rectifier was required to prevent that the crank inductor can damage the telephone or the ears. Also the speaker in the ear piece is very weak and will break instantly if you apply a strong signal without protective circuits.

No.a mis curcuit was formed causing lots of unused electricity and energy from the wire to the wire connected to the earpiece causing the ears to receive the shock since the telephone has holes in the earpiece(this is not digital but an old phone which has holes on it)and causing to shock the ears seviourly.

Not gonna happen, friend, ever. trying to understand your initial post was very difficult. are you talking cell or corded phone? If a cell phone, there is no way there is going to be enough juice in the battery to cause damage like you describe. If a corded phone, the only time ther is a dangerous amount of current is when the phone rings, and 90V flows. At least that was the way it was when you rented your phone from the phone company. Since the break up of Ma Bell, I can't guarantee, becuase all the phones are made by different people. Anyway, I don't think there is any situation where enough electricity is going to leave the phone and deafen someone.

There are spark gaps and varistors everywhere in the phone system to protect the system and the users from lightning hits on the lines. Everything above 120V (no matter if between line and ground or wire to wire) is short circuited.
The whole phone system is digital nowadays. If you use an old phone, the analogue<->digital converter is stationed in the phone company. There's no way that there is an electrical connection between two phones, the "wires" between the phone system's switchboards are fibre optic and all they can do is to carry informations, nothing else!

This has to be bs.
Think about it - if it were possible, how would it deafen BOTH ears, when he only held it up to one ear. Nobody is going to get a shock from the phone that deafens one ear, and hold it up to the other ear. If the same shock deafened both ears, wouldn't there also be some brain damage and probably even death?

Phones don't go berserk. Only people sitting next to a phone user in a restaurant or move theater go berserk.

This may be possible,
As,SOME people make phone wrongly like they say this go here and that go there but it is wrong. And it should be a cable phone. I heared this before and they say that his left ear was bleeding.his right ear not so.I think the wire was placed incorrectly that the function was incorrect so it must be loads of voltage passing through the hearing stuff.As the shock blocker was there ,the wires has differnt function so it must have pass through.

The voltage must have came from the pole wire.u know.

I think this is what you were trying to draw, but I'm not sure why.

digital and analog are irrelevant. A typical phone line carries DC voltage at a few milliamps. You're not going to ever ever get electrocuted from it. Ringing current can hurt like hell but there's no way it's going to the handset.
Look, you're not ever going to get a harmful shock from a telephone unless you're in the sticks and a ton of inductive current got on the line, a cross to a hot AC lead, or lightning strikes the line.
But you're dealing with at best 24ga wiring to the handset. Not a lot of power can get through that before it burns to toast.
