A sound technician is testing the sound acoustics in a theatre for an upcoming music concert. He sets up speakers in different locations and tests the sound levels in various seats in the theater. As he moves down the aisles of the theatre, he notices the pitch of the music gets lower. Which description best explains why the pitch gets lower as the technician moves away from the speakers in the theater?

Diffraction between speakers
Interference of sound waves
Decrease in wave frequency
Increase in wave frequency

I think it is  Decrease in wave frequency am I right?

KyledaGreat · Answer

The correct answer is "Decrease in wave frequency." As the sound waves travel away from the speakers, they spread out and lose energy, causing a decrease in their frequency. This decrease in frequency results in a lower pitch of the music as heard from further away from the speakers. Diffraction and interference can also affect sound acoustics in a theater, but they are not the primary factors in causing a decrease in pitch as the technician moves away from the speakers.
