We’ve all seen people wearing hearing aids but do you know how they work?
Their job is to collect the sounds all around, make them louder and clearer, and then deliver the sounds into the ear.
Some hearing aids are called BTE and others are called ITE. Any idea what they stand for?
Professor Hallux finds out!
