The present invention is directed to an acoustic signal transfer device for transferring an acoustic signal produced by a telephone handset in a test setup. There is at least one valve disk configured to mate with the valve seating surface and at least partially seal the through hole and a first spring configured to bias the at least one valve disk towards the valve seating surface. The bed cover features a split substantially down a center of such bed cover for a predetermined distance so that each person sharing such bed could have an individual preference of being one of covered and uncovered. A precharge signal is applied to the gate of the N-channel transistor.
