An acoustic system comprising an input transducer connected by a first severable path to the input of reverberation means for producing reverberation of the required decay rate of the sound field perceived by the microphone, an output transducer connected by a second severable path to the output of the reverberation means, and detection means which analyzes the status of the sound field or any discrete frequency domain within the sound field and which operates both to connect the input transducer over the first path to the reverberation means and to secure connection of the reverberation means to the output transducer over the second path when the status of the sound field or the discrete frequency domain is analyzed by the detection means as either rising or constant and, conversely, both to sever the connection of the input transducer over the first path to the reverberation means and to connect the reverberation means to the output transducer over the second path when the status of the sound field or the discrete frequency domain is analyzed by the detection means as falling.
