I am 35 years old male, I feel a little light headed throughout the day. This primarily occurs after I speak over my cellphone. I even changed my cell phone to confirm that its not the defective piece that I am using. After a little research, I think noise cancellation feature in cellphone sends a voice signal to cut the noise in outdoor environment thereby disturbing the balance in one's hearing. Other's who used this phone is not affected but I am. I have done MRI with temporal bone but everything seem normal. Please assist me with this.
