I am looking for a solution that would limit the transmitted sound intensity/power in a passive way. There actually already exists such natural limiter caused by the nonlinear sound propagation at high intensities in waveguides. But the required intensity to reach that limit is very high.
I would like to achieve such limitation at lower arbitrary sound intensities. The required component would transmit the input sound waves with little attenuation that are below a chosen threshold intensity, but limit the transmitted signal to a constant max. intensity, if the input signal’s intensity is above the threshold. The component does not have to be an existing commercial component. I am just looking for research subjects that have found phenomena and materials, which could be used for the design of the component.
It is also possible to do this by electronic means, but for my purpose the limiter should be a passive component, as simple as possible.
If anybody has any suggestions about existing solutions, or phenomena that could be exploited to design such power limiter, please let me know.
Thanks in advance.
