- Factual information about significance: The Image Method (IM) is among the most widely used room acoustic models (original IM paper >3,700 citations). We prove that the IM has a problem: it generates 'sweeping echoes' which can sway the measured performances of acoustic signal processing methods including pitch estimation, dereverberation and speech quality estimation, potentially impacting the validity of past/future IM-based studies in these areas. We solve this problem by proposing a modification to the IM which prevents sweeping echoes. Our modification has already been adopted by researchers investigating acoustic source localization, reverb time estimation, speech clarity, and hearing-aid directionality control.
