Devices and methods for howling suppression. One method includes receiving, via a microphone, an acoustic signal from a communication device operating in an acoustic field with the microphone. The method includes determining a reflection pattern for the acoustic field based on the acoustic signal, and determining an acoustic characteristic for the acoustic field based on the reflection pattern. The method includes determining, based on the acoustic characteristic, a plurality of howling zones for the acoustic field, each zone defined by first and second proximity thresholds. The method includes, for each of the howling zones, determining an attenuation level for the zone based on the proximity thresholds and the acoustic characteristic. The method includes determining a distance between the microphone and the communication device, selecting one of the howling zones based on the distance, and adjusting a volume of a loudspeaker based on the attenuation level for the selected howling zone.
