Has anyone has had somebody from Pioneer, or any other manufacturer, actually resolve their specific buzz problem?

Consequently, a vibration will happen on the substrates when the plasma display panel is being driven

However, in the PDP of the embodiment…….there is no possibility of an increase in physical energy being caused by the electrostatic force generated between the front glass substrate and the back glass substrate. In consequence, audible noise produced by the vibration of the substrates is prevented.

It is clear from the results of Table 1 that the PDP of this invention generates significantly less noise than the conventional PDP. Frequency bandwidth Present Invention (dB) / Prior Art (dB) 2.0 kHz bandwidth 9.7 /15 2.5 kHz bandwidth 13.4 /20 3 15 kHz bandwidth 13.9 / 17.6 Entire audible sound 22 / 27.3 bandwidth (50 Hz. to about.8 kHz)

However, in the conventional plasma display module, a vibration absorbing structure is not provided. Therefore, the vibration may be transmitted to the outside, causing audible noise.

Didn't want to post this in the buzz poll as it concerns all PDPs not just Pioneer.

At a certain point you're right but it seems Pioneer is having a problem with inordinately high levels of buzzing as reflected in the Pioneer buzz thread.

I just bought a Pio Elite 151 last week. I had buzzing - noticeable from 16 feet - and it was replaced today. The new set has quieter buzzing, but it's still there. I was all set to return it all and wait for the new Panny's, but this post looks like Panny has issues too. Plus the new Panny Neo panel looks just like similiar design to the Pio...which I think the fusing of the front glass is causing a lot of the problem...it resonates and creates on large focused speaker.
Thoughts?

there's still samsung and lg out there. Try swapping for one of those![]()

Probably getting a Vizio P series to tide me over until OLED, hope I am not too disappointed.Probably returning my 51F8500 to Amazon due to buzzing, just can't get over it when I am watching at low volume at night from ~8ft away.
My 42G10 always buzzed but I got used to it, the buzz on the Samsung is even louder, don't understand how they couldn't figure this out how to fix this in the decade+ plasmas have been out.
