Whales are among the loudest animals on Earth, but even they can be susceptible to harm from excessive or overly loud noise in the ocean.
Scientists have measured blue whales calls as loud as 190 decibels, volume that helps carry their songs and calls across great expanses of ocean.
To the human ear, anything over 120 decibels — about the volume of a siren while standing near the source — can cause immediate hearing damage and pain, according to The Centers for Disease Control and Prevention.
