[0080] The current air pressure reading from the sensor is 5800;

[0081] Subtract the default air pressure value of 5600 from the current air pressure value of 5800 to get an air pressure difference of 200;

[0083] Pronounced using the first octave of a note, depending on the range of air pressure differences;

[0084] Subtract 128 from the air pressure difference to get 72. Use 72 to look up the volume array to get the volume value as 0x63 in hexadecimal, which is 99 in decimal.
