Seems like very misleading science reporting. It relies on the wow factor of a 12mm fish producing a sound as loud as what many people would associate with a jet engine (>140db).
- Sound levels are usually assumed to be measured 1m away. For the fish, it’s measured one body length away (inverse square law applies)
- Jet engines are often measured from many meters away (again inverse square law)
- The fish’s sound is pulsed and lasts only 2.5ms, while jet engine noise is continuous.
- The frequency emitted by the fish “exceeds 20kHz”. The frequency range of a jet engine spans almost the entire range of human hearing.
- Standing next to one might startle you a bit, the other will irreversibly damage you.
