This paper discusses nonlinear acoustic synthesis in augmented musical instruments via acoustic transduction. Our work expands previous investigations into acoustic amplitude modulation, offering new prototypes that produce intermodulation in several instrumental contexts. Our results show nonlinear intermodulation distortion can be generated and controlled in electromagnetically driven acoustic interfaces that can be deployed in acoustic instruments through augmentation, thus extending the nonlinear acoustic synthesis to a broader range of sonic applications.
