Hello and welcome to HCM
The hearing of echo in ear is described as tinnitus
or ringing of left ear.
The hearing of the left ear is not affected.
Is the symptom of tinnitus accompanied by vertigo
(light headedness and sensation of head turning).
If yes then you need to get an examination of your left ear and few investigations- tuning fork tests and sudiometry.
The inner ear
is responsible for hearing and for mainatining balance and equilibrium.
Any abnormality in these functions should be sought out by complete ear examination.
Thanks and take care
