In the discussion regarding the Doppler effect problem, it is established that Ben, walking at a speed of 1.2 m/s, will not significantly experience frequency changes due to the Doppler effect. Instead, the key factor is the distance from the sound source, which affects sound intensity. When Ben is 2 meters away from the bird, he hears a sound at 10 dB. The duration for which he continues to hear the bird is contingent upon his distance from the source and the sound's intensity decay over distance.

Emmanuelle said:Ben is walking in a park in a straight line at 1.2 m/s. A bird is hiding in a bush. When Ben is closest to the bush, he is 2 m away from the bird and he hears a 10 dB sound. How long will he continue to hear the bird?
Thanks for your help!
