Answer -
A 50hz sound is determined to be 65dB by sound meter, this is equal to 40 phons.
supporse a person is subjected to a 65dB SPL tone at 50 Hz would judge this to be equally as loud as 40 dB, 1000 Hz. Hence, the 50 Hz, 65 dB sound has a loudness level of 40 phons. such measurements are also called sound levels.

A whale emits of sound of 50Hz to tell a wayward calf to catch up to the pod. The whale is moving due East at 5 m/s while the calf (1.2 Km away) is moving due West at 4 m/s. The speed of sound in water is 1500 m/s and the speed of sound in air is 340 m/s. a) How long does it take the sound to reach the calf? What is the frequency of the sound received by...
