Hi, I did a hearing test and I'd like to know what the audiologist performed after the tympanometry test. An earbud-like thing was placed in my ear and it emitted very strange wavering sci-fi sounds in various frequencies. Sounded something like this UFO Sound Effect (Royalty Free)Watch this video on YouTube My question is, what kind of a test is that? Since I am under 18 and I was at a children's hospital, was it an otoacoustic emission test? I read that acoustic reflex tests are usually a pure tone. Thanks for reading.
