Tone deafness was a hearing impairment regarding the lack of relative pitch – the ability to discriminate between musical notes. Being tone deaf was having difficulty or being unable to correctly hear relative differences between notes; however, in common usage, it referred to a person's inability to reproduce them accurately.

When the genetically-engineered Humans Lauren, Jack and Sarina sang scales to help Sarina regain her normal speaking voice, Jack jokingly asked Sarina if she was tone deaf. (DS9: "Chrysalis")
