We all love the music that our routines are choreographed to, and that’s why dance competitions usually play your music really LOUD. Sound pressure levels of greater than 95 decibels are common in competition venues. You can easily get an approximate measure of the sound pressure level of any environment you are in with a free smartphone app. (I use Decibel Meter-Free for iPhone.)
Most dance teachers and choreographers are unaware that exposure to sound sources at these volumes (94 db or more) for more than 60 minutes consecutively can cause permanent hearing loss (source:National Institute for Occupational Safety and Health (NIOSH)).
That is why I ALWAYS use hearing protection at dance competitions. You can use the cheap, foam type found in pharmacies, but that type tends to muffle the sound, and is therefore not enjoyable to use. I use Ear Peace protectors, which reduce the volume uniformly across all frequencies. The result is that the music sounds just as good as without the ear plugs, but the sound pressure is reduced so that you don’t damage your hearing or leave the competition with a splitting headache. I find that music actually sounds BETTER at competitions or rock concerts with the ear plugs than without, because at super-loud volumes, music actually distorts in your ear drums. Best of all, you can get a pair of HD Ear Peace protectors, with carrying case, for less than $20.
The other great thing about Ear Peace protection is that you can still have conversations with people that are next to you.
Just as you wear sunglasses in bright sunlight situations, consider hearing protection to be the equivalent device for your ears in loud settings. Do yourself a favor and protect your ears the next time you are at dance competition, especially when the solution is quite inexpensive.
There are many reasons why it’s a bad idea to extract audio from YouTube.
1) It’s illegal.
2) Even pristine audio is somewhat degraded since YouTube uses mp3 encoding of any audio submitted. In many cases, it’s an mp3 of an mp3 of an mp3….. and the audio gets worse every time it’s re-encoded in this manner.
3) But if the above reasons are not enough to convince you it’s a bad idea to extract audio from a YouTube clip, then realize this: In many cases, what you are listening to on a YouTube clip is the room in which the audio was played. Even if the clip doesn’t have audience noises, like coughing, moving around in seats, and other assorted venue noise, the audio is playing back over a sound system, and being picked up by a microphone, along with all of the reverb, reflections, and echoes of the room in which the music is being played. All of these things combined downgrade the audio, sometimes a little bit, and sometimes to the point of pure garbage. But it’s never as clear as it could be. And once degraded in this way, there is no practical way to restore it, except to go back to the original source. That is why, when creating music edits and remixes for dance teachers, Squirrel Trench Audio always goes back to source audio whenever possible.
If you want GOOD, CLEAN audio, DON’T get it from YouTube!
