We know that we humans haven’t great hearing abilities. We are only capable of hearing sounds of 20kHz maximum, dropping to around 12-15kHz as we age
Even dolphins, known exponents of ultrasound, have their limitations are around 160kHz.
Researchers at the University of Strathclyde have discovered that the greater wax moth is capable of sensing sound frequencies of up to 300kHz – the highest recorded frequency sensitivity of any animal in the natural world.
“We are extremely surprised to find that the moth is capable of hearing sound frequencies at this level and we hope to use the findings to better understand air-coupled ultrasound”, said Dr James Windmill, who has led the research at Strathclyde.
Further he explains: “It’s not entirely clear how the moths have developed to be able to hear at such a high frequency, but it is possible that they have had to improve the communication between each other to avoid capture from their natural predator – the bat – which use similar sounds.”
