1. An active analog generating device (12,12a), it is characterized in that;

  • Have;

    (10, Wave data table (48), the reference signal of the transport condition testing agency (30,58) that transport condition 10A) detects, storage one-period Wave data generate the (46a of mechanism to moving body;

    46b, 46c), sound control gear (55), the gain adjusting mechanism (60,60a;

    60b), active analog sound output mechanism (22), active analog sound detection mechanism (24), gain relatively mechanism (76,76a is 76b) with gain correcting mechanism (70;

    70a, 70b)Said reference signal generate mechanism (46a, 46b 46c), according to transport condition, read said Wave data by said Wave data table (48) in order, generate decide the reference signal of number of times,Said sound control gear (55) generates control signal according to said reference signal,(60,60a 60b) has said gain adjusting mechanism;

    The 1st gain table, gain that said control signal is used and said transport condition are stored in the 1st gain table by corresponding relation, said gain adjusting mechanism (60;

    60a, 60b) according to the detected said transport condition of said transport condition testing agency (30,58) by reading with it corresponding said gain in said the 1st gain table;

    After using this gain that the gain of said control signal is adjusted, adjusted said control signal output will gainSaid active analog sound output mechanism (22) is exported active analog sound according to the adjusted control signal of process gain,Active analog sound detection mechanism (24) is arranged near the evaluation position the passenger, and at the said active analog sound of said evaluation position probing,Mechanism is compared in said gain, and (76,76a 76b) has the 2nd gain table (72;

    72a, 72b), in the 2nd gain table (72;

    72a stores prediction gain in 72b), and said prediction gain is the gain of being used by the said control signal that is stored in said the 1st gain table;

    In conjunction with the gain in said evaluation position of trying to achieve to the signal transfer characteristic of said active analog sound detection mechanism (24) by said active analog sound output mechanism (22), said gain relatively mechanism (76,76a;

    76b) the actual measurement gain with the detected said active analog sound of prediction gain and said active analog sound detection mechanism (24) comparesSaid gain correcting mechanism (70,70a, 70b) according to through said gain relatively mechanism (76,76a, comparative result 76b) carries out revisal to said gain through the adjusted control signal of gain.
