The computer model finds that mid-frequency sonar is mostly filtered out for the whales, while the higher frequencies the animals use for hunting appear to be unimpeded by sonar.

电脑模型表明，突吻鲸能过滤掉声纳大部分的中频声波，而声纳也不会影响这些鲸鱼用来捕猎的高频声波。

Hunting Hunting is a phenomenon that can occur upon load changes in which the frequency or the voltage continues to rise above and fall below the desired value without reaching a steady-state value.

Such damage has long been suspected, since whales employ their own form of sonar for navigating and hunting, and also use sonar-like low frequency sound for communicating with each other (so-called whale song).
