âCompressionâ generally means forcing more gas into a fixed volume or reducing the volume of a a closed space, increasing pressure. Increasing chamber size would have the opposite effect.
I donât think it is used that way by harmonica players. In a harmonica, I think it means muffling the sound and reducing the airflow by closing the leakage paths in the harmonica and hand cup. I would like to know precisely how yâall define âcompression.â
In any case, I canât see how plate thickness would have any effect on it.
