Fast Technology, Dec. 6 (Xinhua) recently, a video of a woman calling for a cat went viral, causing a lot of netizens to make a fuss.

Pet blogger @ Chief BBQ Fish Officer (my kitten grumbles) calls her kitten in the video, but is she & ldquo; Mimi & rdquo; or & ldquo; Gollum & rdquo;?? Different netizens have different judgments.

Some people only hear Mimi, some people only hear Gollum, and others can hear both voices.

In this regard, popular science blogger @ Bi explained: the frequency range of each audio segment is actually very wide, including both the high frequency part and the low frequency part.

With 2000Hz as the boundary, audio is divided into high-frequency and low-frequency parts, and the high-frequency part above 2000Hz is played separately. & ldquo; Mimi & rdquo;, plays low-frequency part is & ldquo; Gollum & rdquo;.

If you raise the original material by 12 semitones as a whole, you may hear it more easily & ldquo; Mimi & rdquo;; lower 12 semitones and it will be easier to hear & ldquo; Gollum & rdquo;.

In fact, a similar incident happened once in 2018, when the famous Laurel and Yanny events also heard two different pronunciations on the same recording.

Through voiceprint analysis, scientists found that there were both pronunciations, but with different frequencies.As people grow older, their sensitivity to high-frequency sounds decreases and their hearing changes. Therefore, hearing different sounds may be related to age and auditory sensitivity.

Blogger @ Ansenaacutetello has done more detailed science popularization from the perspective of linguistics, physics and pronunciation, a phenomenon called the ldquo; formant illusion & rdquo;.
