Panel Mode+Tuning Frequency

Panel Mode+Tuning Frequency

Panel Mode+Tuning Frequency

(OP)
Does Panel Mode Frequency & Tuning frequency has any relation for resonator?

RE: Panel Mode+Tuning Frequency

Um, that's a bit incoherent, but no, you do not want your panels on the resonator to have the same frequency as the acoustic tune, if that's what you mean.

RE: Panel Mode+Tuning Frequency

Maybe you are confused. Panel has a resonance frequency, and resonator has one too. You can build a resonators array with a panel or more (perforated) please review www.iperf.org.
I hope help you. Luck

RE: Panel Mode+Tuning Frequency

(OP)
I am little bit confused between the correlation & significance of three terms (a) Panel Mode(Inertance) (b) T-Loss (C) Tuning.

I know by using hammer we can get panel mode frequency.
 
The difference between the noise level at entry & outlet port, we can measure T-loss. (By changing mass & stiffness we can able to change T-loss)

Tuning frequency is the one we wanted to hear. By putting resonator, side branch we can tune the system.

Thanking you in advance,

RE: Panel Mode+Tuning Frequency

Basicly you're right. Concepts are correct, and there are many relations between them and many branches from each of them, in a theoric and empiric sense.

RE: Panel Mode+Tuning Frequency

(OP)
I have one underhood component in front of me & it has minimum panel mode frequency requirement near by 272 Hz.

The panel mode is response/force applied(acceleration)- &  less the response (less the component vibrates), it better.

so does it printing mistake?

Thanking you in advance,

RE: Panel Mode+Tuning Frequency

No, that sounds a sensible requirement. While I appreciate that the internet is free, it might be worth buying a book or going on a course and learning about this stuff. Or ask whoever set the requirement what it means.
