A decrease in voice pitch of 22.1Hz correlated with an increase in company
size of $440 million (£286.6 million) which was accompanied by higher pay of
$187,000 (£122,000) a year.
The researchers also found that male chief executives with lower voices were
retained longer by the companies that employed them.
Professor Mohan Venkatachalam, one of the Fuqua researchers, said: “These
findings suggest that the effects of a deep voice are salient even for the
upper echelons of management in corporate America.”
But his colleague Professor Bill Mayew added: “While a deep voice appears to
correlate with various measures of labour market success, we still have
little understanding of the precise mechanism by which a deep voice adds
value.”
Previous research by Duke
University has found that voters of both sexes prefer candidates with
deeper voices.
