Hello and welcome to HCM
Hearing loud, high pitched and constant ringing noise in ears indicates some pathology/ problem in ear- inner ear
or in the pathway of hearing.
You need to get a complete ear examination.
In case there in wax impacted in the ear canal, it can be removed by syringing.
In case the ear canal is clear, inner ear needs to be investigated by tuning fork tests and audiometry
Consult your ENT specialist
as the hearing loss
can aggravate if not investigated in time
Thanks and take care
