What is tonic deafness?
Imagine getting into a friend's car, pumping up her favorite playlist, then being immersed in the sounds of hundreds of ringing pots and pans. It is estimated that 4% of the world hear music in a whole different way. They were born with a condition, which calls amusia: tone-deafness.
What is tonic deafness
People who are truly tone deaf are not only bad at karaoke, they cannot discern differences in pitch, the quality of music we refer to when we say something is' low 'or' high '. Suppose you listen to your neighbor, who practises piano, for example. In general, you could probably say if the note you just heard was higher or lower than the note you heard before. People who are tone deaf lack that ability. They still hear a difference, but they don't process it in the same way that someone who isn't deaf.
Tonedeafness hereditary
While some people hear pots and pans sound, others may hear sounds they like. In the lab, they check if participants have amuses with a version of this test , which you can try right now. In other words, while some may experience sound in one way, others may experience it in a completely different way. Exactly what causes tone-deafness is still somewhat mysterious, but researchers find some fascinating clues. From studying families, for example, scientists have been able to conclude that it is hereditary, which means that if you have it, your children are more likely to have that too. We also know that amusia is a type of agnosia, a word derived from Greek roots that together essentially means “not knowing”. Agnosias describe conditions characterized by the inability to connect your sensory input (what you see, hear or feel) with your insider information about the thing you perceive.
