摘要： The present invention relates to a microphone test stand comprising a slide assembly with a microphone holder surrounded by a first acoustic sealing member. The slide assembly is movable in a first direction between a first position outside an acoustical chamber with an exposed state of the microphone holder and a second position inside the acoustical chamber in a shielded state of the microphone holder. An electrical connector comprises a set of electrical connector terminals which is connectable to a set of microphone terminals for receipt of a microphone response signal from a microphone assembly arranged in the microphone holder in response to a test sound pressure in the acoustical chamber.
