time and trying to tune to each other. They attempt to play the same note and hear Two instruments, a trumpet and a saxophone, are playing at the same beats with a frequency of 4 Hz. a) If the saxophone player knows their instrument is playing at a frequency of 440 Hz, what frequency or frequencies is the trumpet producing? b) The players get their instruments in tune and play the same note again. Explain why the two instruments sound different, even though they are both playing at the same frequency. A certain steam train engine produces 40,000 J of energy per second. When the conductor blows the train's whistle, a certain percentage of that energy is diverted to the whistle to produce a sound. If regulations require a maximum decibel level of 50 dB at 100 m, what is the maximum percentage of energy that can be diverted to the train's whistle? time and trying to tune to each other.
