No matter where you end up at a music festival, either by the stage or near a speaker, soon you'll be able to control how you hear live music with high tech earplugs.
Doppler Labs has developed these Here buds that connect wirelessly to a smartphone app.
So that's everything from volume control, so you can turn the volume of your real world up and down
To five band EQ.
Adjust the bass and trebles in your world.
And effects, so you can add flange, or reverb, or echo.
The buds are designed to let you hear the world around you, but damping annoying noises, like a car alarm or a crying baby.
So take a baby crying, that's another specific frequency range.
And what we're able to do is identify that frequency range Say look, we wanna let the other audio through but we're gonna create anti-noise where the baby is crying so that that does not make it through.
I tested the prototypes out at San Francisco's Outside Lands music festival.
And there's a lot more treble.
I can hear those things very clearly.
You can actually hear it come through.
At Outside Lands it's not just tech for your ears.
But, also your hand.
Guests using wrist bands with radio frequency identification are able to enter the festival and pay for wine.
For the first time, the festival is experimenting with beacons that send smart phone alerts.
When you cross a certain area, it pushes you a notification.
It tells you to do something or move a certain way.
To boost smartphone coverage for the 200,000 plus attendees, AT&T and Verizon set up cell sites on wheels.
AT&T added 50% more LT and capacity over the last year with the help of these new cheese wheel antenna.
Cheese wheel antenna will allow us to have ten times the capacity of another antenna that we deployed in the past, which allows us to concentrate the RF signal to a narrower beam.
Serve our customers so we section that out to provide greater capacity.
Over three days AT&T customers used more than seven terabytes of data.
That's more than 21 million social media posts.
For festival goers, technology truly is music to their ears.
