Google Bernoulli's Principle. Air within a port will have increased velocity compared to within the box. The velocity drops back down when it exits the port. It has no effect on the speed of sound or of a sound wave radiated by the port. Excess port velocity, due to the port area being too small, will cause chuffing noise.
