Fresh off her controversial performance during the presidential inauguration, pop singer Beyoncé is scheduled to perform the halftime show on Sunday. The singer’s version of the national anthem earlier this month made news when media learned that she lip-synched the song.
Will she or won't she during the Super Bowl?
Whatever the case, Pantelis Vassilakis, professor and chairman of the audio arts & acoustics department at Columbia College in Chicago, breaks down a few important acoustical aspects of Beyoncé’s show at the Superdome:
1. Speaker Arrays. “Set up in such a way that provides uniform coverage in the audience area and supports minimal bleed outside them.”
2. Sound Check. “Staff should be sent outside the stadium to measure sound levels at a variety of distances from the venue and ensure they are within any legal standards.”
3. Earplugs. “Musicians, sound engineers and stadium staff should be provided with earplugs.”
4. Safety. “Sound levels in the audience areas should be set so that they do not exceed the safe hearing standards for the given exposure duration of the audience.”
5. Loudness. “Engineers should be expert enough to understand how perceived sound level can be increased without necessarily increasing sound pressure levels.”
