Both individuals with normal or impaired hearing (problems of the outer and/or middle ear) can experience the work
Internal sounds are re-internalized in an audible way without the air medium. Inner soundscapes have been recorded through contact microphones, which function as sound transducers. The transmission of the sound is realized through direct contact of the "stethophone" to the head - bone conduction - thus creating a full closed circuit, starting from the contact recording of the inner sounds to the contact transmission of them.
During this chain process, the sound is being kept internal and is being reproduced again internally, directly to the inner ear, deviating the air transmission of sound waves which is the hearing through the external ears.

Internalizing audible the electromagnetic (EM) oscillations into the perceiver's head, with a conductive use of sound, bypassing the air medium. The participant is detecting EM oscillations while moving through electronic and electrical devices. The "stethophone" transmits sound straight into the inner ear when conducted to the head (to various positions where the sound can be clearly conducted). Pair of earmuffs, a "stethophone" and an EM detector are available for the participant. Once she/he has plugged the ears, they can detect EM oscillations by moving through space and perceive the sound by conducting the "stethophone" on her/his head. The whole procedure is completely silent - no sound is perceived through airwaves.

The perceiver uses earmuffs and a pair of gloves. Through the contact of her/his two palms against the head, to various positions, the sound is transmitted directly to the inner ear through the skull (bone conduction). The fact that the gloves are wireless, permits total freedom of movements to the participant. Also, there is no space-specific limitation (as long as almost any outdoor or indoor city space is surrounded by electromagnetic oscillations). The use of gloves as a sound perceiving medium creates more unity between the corporeality of the listener (aware of listening without the use of the ears). While ears enclosed, the body relinquishes the feedback action of its own sound while contact between the body and its surroundings is reduced. Instead, the body expands inwards by extending the perceived space of the mind, thus an awareness of the head as hearing space occurs.
