It brought back the nostalgic feeling of when I could use a stethoscope, and I was so happy and move

I would like to introduce you to Ms. Miyuki Yamamoto. She has a progressive sensorineural hearing loss and is a nurse who wears a cochlear implant. ShareMedical Inc. receives many inquiries from doctors, nurses, medical students, nursing students, and universities who are interested in pursuing a career in medicine with hearing impairment.

One of the letters we received this time concluded that "the sensation of listening with the old stethoscope and the feeling of listening with Nexstetho were the same," and our staff was very happy that Nexstetho could be a medical ear.


My hearing is 104dB on the right and 105dB on the left without any cochlear implant. There are 24 electrodes in the cochlear implant that transmit sound, and I turn off several electrodes for high-pitched sounds in my right ear because high-pitched sounds give me a headache. I hear sound differently in the left and right ears, but the mapping (adjustment) is done so that there is a balance when I listen with both ears.

I have had a cochlear implant for 8 years, and until 9 years ago, I was a nurse in a normal clinical setting and did audiology.

The cochlear implant is a Cochlear Nucleus 5, which is two generations old and cannot use Cochlear's streamers. As a cochlear implant system, I use a Phonak Roger Pen.

(1) Direct audio cable connection between Nexstetho and cochlear implant.

This connection method was the best for me. The sound reaches the cochlear implant directly. By turning on both the I and II buttons, the ambient noise disappears and the heart, breathing, and intestinal peristalsis sounds become easier to hear. Since there is no audio cable for both ears, the two earphone jacks can be connected to each ear to listen with both ears. Since I hear sounds differently on each side, being able to listen with both ears is important and very good.

(2) Connect Roger's pen to Nexstetho and attach a receiver to the cochlear implant to send sound.

The hearing was good with this method, but I felt that there was a little noise coming from the Roger Pen.

It was convenient to have a receiver attached to the cochlear implant and a Roger Pen connected to the Nexstetho so that I could simply turn it on and start listening whenever I wanted to.

The sound was adjusted to be easy to hear by adjusting the I and II buttons according to the surrounding conditions and noise, rather than the frequency. It is difficult to distinguish between noises and abnormal sounds when there are noises, so I appreciate the ability to adjust the sound so that noises can be reduced and I can hear them.
