Schwannoma is tumor from, Schwann cells that protect and support the nerve cells of the nervous system. It is the eye it causes blur vision.
Schwannoma Schwannomatosis Plexiform 6588-1 Hz
Schwannoma Schwannomatosis Plexiform 4340 Hz
Schwannoma Schwannomatosis Plexiform 1758-7 Hz
Schwannoma Schwannomatosis Plexiform 4202 Hz
Schwannoma Schwannomatosis Plexiform 1250 Hz
Schwannoma Schwannomatosis Plexiform 7250 Hz
Schwannoma Schwannomatosis Plexiform 2780 Hz
Schwannoma Schwannomatosis Plexiform 700 Hz
Schwannoma Schwannomatosis Plexiform 350 Hz
One effective combination is,
Schwannoma Schwannomatosis Plexiform 350 700 2780 Hz
Another set of frequencies for hearing loss due to Schwannoma is,
Schwannoma Acoustic Vestibular 6243-7 Hz
Schwannoma Acoustic Vestibular 4255-2 Hz
Schwannoma Acoustic Vestibular 3075 Hz
Schwannoma Acoustic Vestibular 1225 Hz
Schwannoma Acoustic Vestibular 7500 Hz
Schwannoma Acoustic Vestibular 2500 Hz
Schwannoma Acoustic Vestibular 970 Hz
Schwannoma Acoustic Vestibular 620 Hz
Schwannoma Acoustic Vestibular 350 Hz
and also,
Schwannoma Acoustic Vestibular 350 620 970 Hz
Maybe vestibular Schwannoma is the reason we lose high pitch hearing at old age.
Good luck.
