. This paper collcerns a ftmdamental sohltion methQd applied to Neulnalm boundary value problems Qf two dimensional reduced wave equations ill the exterior regioll of a disc. A criterion for t. he unique solvability of the derived appro . 7cimate problems and an error estimatioi ユ for their solutions are obtained . The obtained decay rate of error is asyl 皿 ptotically expollentiaL SQme results of our numerical experimellts are also reported , wllich support the effectiveness of multiple −
