摘要： According to one embodiment, a sound processor includes a creating module, a filter, and a combining module. The creating module creates a plurality of first acoustic models based on a frequency characteristic that represents an acoustic property of an object to be measured. The first acoustic models are modeled with respect to resonance properties that vary depending on frequency bands. The filter extracts frequency components in the frequency bands from the respective first acoustic models. The combining module combines the frequency components extracted from the first acoustic models to create a second acoustic model.
