Abstract

The report presents positive results of small scale measurements with active echo-damping by use of a single transmitter. The measurements are found to be in agreement with theoretical considerations. If the model results are scaled up a factor 100 they mean that at least 10 dB damping can be achieved in a direction range of 10-20 degrees for an object with 3 m radius and at a frequency of 1000 Hz.
