I am stumped analyzing the transmission of sound through a rectangular slot in a thin rigid wall. I have found online that a square or round aperture acts as a highpass filter with a 6dB/oct slope and a corner frequency where the wavelength is on the order of twice the aperture diameter.
I have reasoned that a rectangular aperture would act as a highpass filter with a 6dB/oct slope up to a corner frequency where the wavelength is twice the slot length, then a 3 dB/oct slope up to a corner frequency where the wavelength is twice the slot width. I would like to have this confirmed or refuted.
