It is no secret that prolonged exposure to loud sound is highly damaging to our hearing. Listening to loud music is one of the common factors leading to degraded hearing ability and tinnitus, and is deeply unhealthy.
At the same time, such level of noise negatively impacts the quality of sound perception, which degrades the musical side of the musical performance.
In what seems to be the echoes of the so-called “loudness war”, bands still stick to the idea that “the louder you blast it - the better”. But it’s not true. There are many other ways to energize the crowd without causing them sound damage, and I’d love to see more of those, instead of them trying to be the loudest ever.
This gets into some funny spaces. Your ears can only handle “so loud” before things start going weird. Muscles start tensing up to attenuate the noise. The shape of your ear canals will funnel sound so your hairs in your inner ear stop hearing and just report noise.
Turning down the overall volume, lets you hear more, because more of the sound is in your range of acceptable volumes. I’m more aware of what’s going on with earplugs in, because I’m able to hear things like the tire noise of a nearby car, or the cooling fans of a semi.
This is the same reason wearing earplugs at concerts makes the music sound better. :-)
