My mom, who is now 58 in American age, received a heart valve replacement surgery mid-January this year. It was her second surgery regarding the heart valves. Although the first one gave as much pain as the second surgery did, it did not involve the actual replacement of heart valves. Sort of rings were installed in around her heart at the time. In the latest surgery, however, she had two of her heart valves replaced with mechanical ones. She and my family simply thought the second surgery would make things alright, but troubles did not easily go away. Since the mechanical valves make some constant clicking sounds, she and even other people around her can hear the noise from the heart devices, even in distance in a quiet room. She became very anxious and stressed out due to the relentless noise, and I felt really sorry for her suffering. I've really wanted to give her some help to alleviate her stress from the noise, and I came up with an idea.
To sort of fight back a certain noise, I thought a noise in a similar frequency is needed. This sound has definitely worked for her, and she said she is now able to sleep more comfortably with this white noise playing than before. Hope this video also works for other people who have been suffering from noises from mechanical heart valves.
