摘要
提出了用于评价单个传声器互易性的系数T_a,对基准传声器(BK4160,№ 991803)的T_a值作了实际测试,并以此T_a值评价了该传声器的互易性。还指出了单个传声器互易性评价对φ2.7mm标准传声器互易校准的应用前景。
In this paper,a coefficient Ta is introduced for the reciprocity assessment of the single microphone.The Ta of a standard microphone(type BK4160,No.991803)is measured and the reciprocity of this standard microphone is assessed with Ta The application value of reciprocity assessment is also discussed.
