Eardrum-pressure recordings exhibit spectral peaks caused by the natural resonances of the external ear. Under diffuse-sound-field recording conditions (which are encountered in most music-listening settings), the principal peak amounts to approximately 15 dB at 2700 Hz. In many cases, use of the simple bridged-T equalization filter described here will provide improved naturalness in the reproduction of eardrum-pressure recordings.
