I can attest to the loud music thing.
Do NOT take your EVO to any club. Let me tell you. You can separate everything, and you will still see your battery 'bouncing' to the beat. I even wrapped mine in a bunch of bar naps and it kept blinking away like a damn strobelight.
This is apparently one sensitive piece of equipment. I also had my penstyle on me, and it's still vaping like a champ, while my EVO battery is dead as Jerry Garcia.
The most salient point in this situation is exactly what you refer to:
"This is apparently one sensitive piece of equipment". Electronic cigarettes are finely tuned microelectric instruments that have to withstand extraordinary abuse from the mixture of rapid heating & cooling and having sticky liquid dumped all over them.
Keeping the battery separate will save the vaporiser and will not drain the charge excessively just by the blinking LED.
Now to the audio problem for those not aquainted with the properties of soundwaves. Bass frequencies produce long waves and move an incredible amount of air, even when the sound to our ears doesn't seem as loud or perceptible as the higher treble frequencies. Bass also consumes a lot of power in its generation compared to high frequencies.
Holding a battery such as the EVO near a high frequency speaker might not activate it unless turned up to a high volume. Holding it anywhere near (or in the general vicinity of, depending on the volume) a bass speaker or sub-woofer will activate it even at low volume.
This is all down to the air movement. Bass cabinets will have a port, or opening, usually at the front of the cab, to allow air to escape. If they didn't have that 'safety valve' the speakers could easily blow themselves up and I have seen it happen with home-made speaker cabinets that had not been ported (many years ago seeing an 18" 500watt Celestion driver self destruct at the hands of an amateur cabinet builder brought a tear to my eye). The term 'tuned port' refers to the size and depth of the port being precisely set according to a specific formula based on measurements called the Thiele Small parameters. These standard measurements are used to match the cabinet and port size to each individual speaker to give a true and even reproduction across the frequency range without distortion or overloading - how many times have you heard cheap or badly designed bass cabs 'farting' like a cow?! The lower the frequency, the more air is moved and at the very bottom end, 41hertz for open E on a 4 string bass guitar, there is a huge amount of air being pushed backwards by the speaker and out through the port. Even lower frequencies can be obtained with 5-9 string Bass guitars going to a virtually inaudible 17hertz and electronic devices such as keyboards etc generating the sub audio range. The bass at these frequencies is not heard but felt and caution must be exercised to avoid the pulping of internal organs by subsonic frequencies as low bass easily penetrates the human form.
So, to put it bluntly, you could shove your ecig up your rectal passage and vape in a way hitherto unknown to man!! Cue Trumpybloke!
