President Park Geun-hye sounded "2.5 times" more excited than usual during a nationally televised address on Monday, an acoustics boffin claims.
Park was urging the National Assembly to pass her government restructuring bill.
Bae Myung-jin, a professor of electronic engineering at Soongsil University, on a chat show on TV Chosun on Tuesday explained that Park usually sounded calm and stable as a presidential candidate, but during Monday's address "she was about 65 percent agitated."
Bae says he compared the vibration of her vocal chords on Monday with those in a TV debate amongst presidential candidates at the end of last year.
"That level is often found among people who are letting out pent-up anger and frustration," he added.
