Sai Ram,
I have found a website whith the Subject: Sloka to overcome hearing loss.
There is a response from: Pandit. Dakshinamoorthi R,
Council Member on Ammas.com
Dear Member:
The 52nd slokha of Soundarya Lahiri (beginning with "gati karnaabhyarnam......." 1000 times for 45 days will help in curing ear diseases.
The yantra is a simple square pattern with the beejam "ram" (the short vowel....as in gum) inscribed in the middle of the square on a gold plate. You can inscribe the yantra in holy ashes also.
The offering is sesamum rice and milk paayasam.
May your disease get cured by Goddess's Grace.
Blessed be.
