System for generating a diffuse noise field and a measuring system for testing objects in terms of their behaviour in a diffuse noise field

摘要

System for generating a diffuse noise field within an area 4 by means of a number of transducers 15, particularly relating to the measurement of the behaviour of objects in "ambient noise", such as "listener sidetone" measurement on telephone terminals 17. The transducers are connected via a distribution device 16 to one common noise generator 3, the distribution device connecting the transducers in a time-division manner to the common noise generator. <IMAGE>
