Mechano-acoustic
WebSolved by verified expert. 1. The acoustic pathway through the cochlea involves sound waves entering the external auditory canal and passing through the tympanic membrane (ear drum), which vibrates in response to the sound. The vibration is transmitted to the ossicular chain, which consists of three tiny bones, the malleus, incus, and stapes. WebHere, we describe a wireless device designed to be conformally placed on the suprasternal notch for the continuous measurement of mechano-acoustic signals, from subtle vibrations of the skin at accelerations of around 10 −3 m s −2 to large motions of the entire body at about 10 m s −2, and at frequencies up to around 800 Hz. Because the ...
