Question

6 Calculate the speed of sound in the example of echoes. Use the formula
distance
speed
time​

Answer 1

Hi here is your Answer:

Echo : In audio signal processing and acoustics, echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener.

Echo time : Echo Time (TE) is the time between the 90° RF pulse and MR signal sampling, corresponding to maximum of echo. The 180° RF pulse is applied at time TE/2. Repetition Time is the time between 2 excitations pulses (time between two 90° RF pulses).

We know the speed of sound is 340 meters per second, so the speed of sound is 340 meters per second. That equals distance divided by time. The time is 1 second.

Hope it Helps.............
