Here is an original introduction "in 1khz SPL， 1khz is that most people are most sensitive to the frequency of the sound， the closer this frequency， the most likely to be heard， that is easy to pass further， unfortunately， a lot of outdoor additional lifesaving whistle， is far from the frequency. the test data is only for most people， but this section whistle is already done. "in addition， this section can whistle like environment on land or on water， diving sounded use.
