It can be done in a single day provided you come early in the morning for the ENT checkup and come equipped financially to purchase the suitable hearing aid (can cost anywhere from ₹10,000 to₹2,50,000 per ear). However certain custom aids (in-the-canal type or complete-in-canal type) will take about a week for delivery of the custom moulds.
