I also don't like your sarcasm or your manners, your opinion holds no wright to me because you ptesented it in a rude and belittling manner. Remember the one who attempts to make others look small is in fact the small one.
Just another case of Royboy talking out his hippie arse.
If it isn't fin hum you may have a small creature or fairy type thing living in your board. I've heard a lot of shapers try to trap leprechauns and fairies and stuff and actually glass them into their boards in order to make the "magic board." Often times leprechauns and fairies, etc. are not visible or audible to regular people unless they are believers. I'd chop up that fairy laden board of yours, catch that leprechaun, steal the gold and have Roy custom make you a 24' yachtboard.
what I do know is that its definitly not foil error or any crazyness that Roy suggested... but upon listening to it it could be wind rushing by the camera housing (like you mentioned)... but I feel like its just noise of board traveling over water at a higher speed which is magnified through the board and thus picked up by the camera...
here's a clip... around 18 seconds you can hear it for about 2 seconds...
It can occur from damage or from a foiling error. The sound is exactly like that in your video clip although it can occur at various frequencies and volumes.
If you attend to the trailing edges of your fins I guarantee that it will cease.
The sound is in the audible frequency range so it is a sound which the human ear can hear, it is however of low volume so it can't be heard when riding.
the videos I can hear them in... the camera is one the deck of the board and its picking up things the human ear can't hear.
How do you come to that conclusion? Vibration due to fin anomaly can be of low or high volume.
I have never heard the noise while surfing so its not foil error.
Your video is a great example of the phenomenon.
Sorry but that is ridiculous, since the board planes as soon as it catches the wave. Planing speed is only about 3 to 4 mph for a 9 to 10 foot board, the wave front moves faster than that so you wouldn't be able to catch the wave without planing.
Its something that happens when a certain speed is reached and is only a quick short lived scream that is most likely do to the board starting to plane on the surface of the water.
Surfboard hulls don't make that noise, it's always the fins.
Do you have fin boxes? If you change your fins or fix them you'll notice the difference.
