Doesn't wind fool this?

Theoretically wind can be Nulled with a 4-way water splitter that are placed in 90° angles (+ a connector at the bottom to the sensor). As long they are orthogonal the wind pressure coming from one side will cause a negative pressure on the opposite.

Only pressure waves coming into all holes at the same time will reach sensor.

Never tested it. Only a Gedankenexperiment as Einstein would say.
