Question

i)What is the frequency of sound that a blue whale can hear?​

Answer 1

20 Hz

Instead, our hearing threshold is different for sounds of different frequencies. "Blue whales call at 20 Hz and sperm whales at around 10 kHz," says Wahlberg. For us to hear blue whale calls, they must be made at an intensity of 70 dB or more. But for sperm whale clicks, the human hearing threshold is around 15 dB.

Answer 2

Answer:

Some whales hear well down to 16 hertz (or cycles per second), versus our lower limit of 50 hertz, while others hear as high as 200 kilohertz. The typical human high-frequency cutoff for humans is 16 kilohertz
