It was observed that the conventional one-half frequency undertones primarily occur above 2500-3000 Hz. In a series of experiments, these subharmonics were monitored in the sound field in front of the tympanic membrane, while first the cochlea and then the stapes were removed. It was found that the presence of the cochlea or the stapes is not necessary for the generation of even subharmonics. These distortion components are radiated by the nonlinearly vibrating eardrum.
