A theoretical analysis is given for the acoustical behaviour of the pipe-microbarograph systems used to detect acoustic gravity waves and other modes of infrasound. It is shown how to compute the response of the microbarograph to a fluctuating pressure at any one inlet port of the pipe and how the results of such …
