(57) and a device for receiving with underground listening device and / or hydrophones, seismic waves, [summary] The present invention relates to a method for combining such a device in a solid environment, such as underground zone. The device, liquid is filled, one end is closed (9) the sealing plug having a sealing duct cable connecting signal acquisition means (E) a hydrophone (10) for flexible and a hydrophone (2) at least immersed in (7) a housing having walls. The housing is disposed cavity (6) within, by using a settable material such as cement, preferably, it is closely coupled to substantially all over the environment. Can be provided underground listening device in proximity with (7) housing containing the same binding material, the hydrophone (2). Are useful for earthquake or auditing underground exploration behavior underground structure, the present invention is useful when increased seismic and especially to determine the seismic wave down.
