Calculate sound pressure inside a cavity

[SFB]

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

in advance.To calculate the sound pressure inside your channel, you will need to know the transmission loss of the channel and the power of the sound source. The transmission loss is a measure of how much energy is lost when sound is transmitted through the channel, and is usually expressed in dB. The power of the sound source is typically expressed in Watts. Once you have these two values, you can use them to calculate the sound pressure in the channel by applying the following equation: Sound Pressure = 10^(Power_of_sound_source - Transmission_Loss) / 20 This equation will give you the sound pressure level in decibels (dB). To get the actual sound pressure, you need to multiply the dB value by the reference sound pressure which, in your case, is 1 microPascal. Hope this helps!
