Sound or acoustic energy was a form of energy which propagates through matter and is received by a being or device capable of interpreting it. Its intensity can be measured in decibels, while the pitch of sound is measured in hertz. (citation needed • edit) Most, if not all, species known to the United Federation of Planets were naturally capable of perceiving sound through a sense called hearing.
