<div dir="ltr">RSZA says that one who can hear only using a hearing aid cannot fulfill the mitzva of shofar<div>since the hearing aid converts sound waves to a vibrating membrane and then back and this destroys the sound</div>
<div>(I have heard that others allow if the person has some minimal hearing)</div><div>RMF disagrees in fact quoting science that sound waves are really the motion of air molecules and a vibrating membrane is</div><div>not intrinsically different.</div>
<div><br></div><div>I havent seen teshuvot about cochlear implants but it would seem that this is okay and it is now part of the body</div><div>and not different from the vibrating membranes inside the ear.</div><div>I recently read that they are actively working on a bionic eye. Again the question is whether such an artificial eye would be</div>
<div>the equivalent of full sight (eg a blind person is exempt from various mitzvot especially ones like reading the megilla</div><div>which cant be done by heart).</div><div><br></div><div>Does anyone know of teshuvot about bionic ears or eyes?</div>
<div>In the not so remote future many parts of the body will be able to be replaced by artificial working alternatives which lead to a whole host of questions<br clear="all"><div><br></div>-- <br><div dir="ltr"><font color="#000099" face="'comic sans ms', sans-serif">Eli Turkel</font></div>
