Abstract
The invention relates to a controlled acoustic wave guide configured as an elongated hollow chamber (1) which via an opening (2) in its first face end (3) is connected to a sound-conducting channel (4). The longitudinal resonances of the hollow chamber (1) can be adjusted to a sound spectrum to be dampened. To this end diaphragm vibrations are detected by means of a microphone (10) which is positioned directly in front of the diaphragm (8) of at least one loud-speaker (9) at the second face-end (6) of the hollow chamber (1). The microphone signal is then inverted using an amplifier (11) and fed back to the loud-speaker (9) after amplification in accordance with a sensor (12) signal characterizing the sound spectrum in the channel (4).
