FedEx crowd noise

[FRPLG]

I sit in 436 and I can guarantee that we piped in the crowd music. The speakers are pointed right at me. Now was it simply piping in the crowd noise from the crowd?...probably Is this illegal? I don't know but it shouldn't be. I believe the Colts got in trouble for piping in false crowd noise with speakers directed right at the field. The speakers I am sure were running noise were pointed away from the field.
