The constructions of directional microphones of the "linear" type and the test procedure are described. On a controlled lane of the highway, full-scale studies of microphones produced by the authors were carried out. Thus, the relative error in the measurement of microphones No. 1 and 2 was found, which was 12.1 and 13%, respectively. The minimum error is detected with a microphone of the "linear" type No. 1, whose slots are located on the sides on four sides
