My Dumb Question of the Day

Gosh!!!

What 4 the JC sake R U talkin' about???

What kind of efficient transfer???

It's NOT sound waves are being transfered but mechanical waves of stylus induce electro-magnetic force emf across the coil of cartridge as per Faradeys' Law of electro magnetic induction. Hearing mechanical waves of stylus being transfered to the air is absolutely irrelevant to the conventional analogue reproduction.

Earlier in mechanical gromophones the mechanical vibrations of the needle were transfered acoustically through the brass horn. Well, nowdays we have better solutions than brass horns(again mr. Faradey comes very handy) and to "preserve" this "wasted" energy try to use microphones with all applied stuff such as mike amp or mike preamp input, mixer(the device that takes many input signals at the same time)... Gotta be those high sencitivity ones from recording studios next to the cartridge or simply you may use karaoke machine he..he..:-).

It's called "needle talk". They all do it. Just a guess, but I bet it comes from the compliant vinyl reacting to stylus forces. The stylus wouldn't have enough area to produce audible sound.

Hi Jpharris,

I'm a "newbie" to analog/turntables, but I think you are asking an intelligent question...at least based on the answer to your question that I found here:

Lots of idle chatter & smart alec remarks but no real answer until Wes came to the rescue. Thank you, Wes!

Indeed, Jpharris, what you are hearing is shock waves as outlined in the turntablebasics.com website. I was going to reply to this effect but Wes beat me to it. I'm a bit surprised that a cart. w/ a quality as high as Aurum Beta S is producing shock waves! I have heard the same cart. on a Nott. Interspace but it was quite as can be. I wonder what the reason might be in your setup??
I once had an AT96E cart. on an old Dual & it produced loud shock waves that I could hear at my listening seat & in the whole room, in fact. My G1042 is much better - stuck my ear as close to the cart. w/o touching it or the tonearm or the LP - not a squeak.
