Portable dvd player on plane??

Maybe it wasn't this thread, although I thought it was, but I'll repeat because you obviously didn't see it.

It's pretty much accousitcally impossible for the bass sounds of an IPod or Walkman to travel past the ears of the listener.

Headphones and ear buds are unidirectional. They thrust sound in one direction, and one direction only--into your ears. They lack sound pressure substantial enough to force sound into an omnidirectional pattern. They also lack subwoofers, the system of electrical impulses (analogue or digital) that handle the lowest frequencies, 20-100Hz range. These sub sounds require air pressure to move through the atmosphere, and these devices son't produce air pressure. (This is why when you hear a car with a loud BOOM-BOOM-BOOM coming from it's sounds system you can feel the vibrations, it's actually the air pressure needed to carry those sounds which is literally physically produced.)

Your ears act to interfere with the sound spectrum, and block some frequencies from traveling further.

High end frequencies travel with minimal physical air pressure and can reflect off solid surfaces. These would be the 15-20kHz frequencies.

What you hear from someone's headphones or ear buds are the upper range frequencies, and depending on the volume and quality of the apparatus, some of the upper end mid-range frequencies, not the low end or bass frequencies.

It's physics. Nothing more, nothing less.

Boy, someone sure knows her physics!!!

But I think we all knew what the poster meant.... The cacophony of treble sounds coming from a headset can sure make a person wonder how many times that person is going to say, "WHAAAAAT???" when they get old!

Hey, I found my dd---> she plays the viola. I wonder if the people around us on the airplane would mind if she practiced on our next trip to Orlando.

Back to the action:

hey, my dd plays viola too. She won't mind if your dd practices, as long as she can play along. We'd have to coincidentally be on the same flight. Think we can work that out? But I think we should get them electric violas, so they can plug in headphones. Just to be safe. Really, though. Speaking of that, mine leaves for string camp on sunday. You know, "One time, at string camp..."

Geez Anne, and this thread was just getting so nice again.

Actually, I did read your pp. I was replying to the post above mine and trying to lighten everything up. And anyway, yes, I did hear JUST the bass from the person in front of me. They were not wearing ear buds, they were wearing the plain, ordinary older kind of foam-covered headphones. Don't ask me to explain it, I certainly know enough about music to know what bass sounds like. I even appreciate pretty much any kind of music, but I prefer to hear all the sections, not just the bass.

String camp?? I didn't know such a thing existed! Probably because my daughter hasn't wanted to go and chose not to tell me. She is going on her 6th year of playing and is currently into learning all of the Phantom of the Opera songs. At her last concert, she played the theme to the Lord of the Rings. I'm just glad the "My Heart Will go On/Titantic" days are long over! I've heard that song a gozillian times during her 6th grade year. Every year she has a favorite that she latches on to and she plays it over and over and over.... Her orchestra at school always plays classical music - so, we do get a variety of stuff to listen to at home.

Awsome photo TNT, we did the same exact thing when traveling with another family a few years ago and it worked like a dream. Those particular earphones did the trick for us too but I still bought a couple of different (cheap) styles for my little one to try, their ears are so differently shaped that its hard to say what will work for each kid.

Even better is the fact that most portable DVD's can be plugged in at an outlet in the airport so the kids were watching a movie QUIETLY during our take off delay.

With my family I try and keep things peaceful for everyones sake but there are people in this world who just can't stand kids and there is nothing you can do about it. When you're flying (or at a restaurant) just remind yourself that you'll never see those people again and try to not let them ruin your day by getting you all hot under the collar with your family. It happens to everyone.

I know what you mean. DD12 is going on her 6th year also (9th grade). She was also in the Honors level ensemble, so got more interesting songs, Thank Goodness! Her music teacher begged me to get her into a summer strings program several years ago, and began giving us brochures. We picked one at Baldwin-Wallace (a college) and this will be her 3rd year doing it. Now THEIR concert is impressive!

I asked my 3yo dd to try a set of headphones. She didn't like them (old fashioned regular foamy ones). So I asked her why not, and she told me that it's "not a very pretty headband." She says she'd like them if they were Princess ones...a set of Princess stickers all over the headband part did the trick. Just some advice for other girly-girl moms!

Nah, I don't really know the first thing about physics, except where it comes to audio engineering. And even then my knowledge is very basic.

Then whatever they wre listening to must have been a remix where someone EQ'ed the mix to be low end-centric, and their headphones weren't properly positioned on their head.

Either way it had to have been over 90Dbto be heard by another person and over engine noise and cabin white noise, which is a level that causes hearing loss.

Anne

PS--I'm a freak about hearing loss. I actually wear "foamies" when driving my convertible because the roar of the wind in my ears is loud enough to cause loss over time. When I go to concerts I wear custom made ear plugs that cut 30 Db of sound across the entire range of attenuation. In other words, it still sounds great, but it's a lot quieter. They run about $75 and I highly reccomend them for people who enjoy councerts. Any audiologist can get them made for you, they are commonly referred to as "musician's ear plugs."

Wow, thanks for the idea. I stopped going to concerts, or even to clubs with live bands, because the sound level is so disturbing for me.

Oh, and the girl's headphones were DEFINITELY not on her head correctly. She had them way forward and "Aimed" toward her ears. They were cockeyed. It's hard to describe. maybe she didn't like the feel of them pressing on her ears, I don't know. I just know it "sounded" like a headache, like a throb, throb, throb. Thanks again for the earplug info!

That's a good idea! I'll have to remember that when I buy her 1st set; which will be very soon for our long car ride up north.
