## Main Question or Discussion Point

How do I calculate sound pressure inside a channel. I have a channel of 40 mmx 40 mm cross sectional area. I have placed a sound source on one of the side wall that resonates at 50 Khz.

I know the voltage required to drive the transducer. The transmit voltage response of the transducer is 110 dB for a reference of 1 microPascal at 1 m.

I do not really know if I need all the above mentioned specifics for such calculation.I am not yet very familiar with acoustics but I would really appreciate if anyone can help me understand and calculate the whole thing .

Thanks
