Dolphins give birth to a single baby; the baby is usually born tail first (unlike most mammals) to minimise the risk of drowning. Likewise, which animal can hear ultrasonic sound? Was this answer helpful? UC Berkeley physicists have used graphene to build lightweight ultrasonic loudspeakers and microphones, enabling people to mimic bats or dolphins' ability to use sound to communicate and gauge the distance and speed of objects around them. These tones occur regularly in the animal kingdom and are used not only for communication (dolphins) but also for localization (bats). Based on publications in medicine, we will show that ultrasound emitted by dolphins could have an effect on biological tissue under some circumstances; such as sufficient intensity, repeated application over several days or weeks and a certain application duration per session. Bats do it, dolphins do it. Moths even can hear the bats' ultrasound, helping them escape predation. Dolphins can hear ultrasound with frequencies up to 280 kHz.
